Testing Sites.Selected SharePoint and MS Graph API

Sites.Selected MS Graph API permissions were introduced by Microsoft in March 2021. One year later, in 2022 they added SharePoint Sites.Selected API permissions.

Azure registered app with SharePoint and MS Graph API Sites.Selected permissions

Why is this so important? Because MS Graph API for SharePoint is still limited and cannot cover all possible needs. I’d estimate: 90% of applications use SharePoint CSOM, so developers have to use AppInv.aspx to provide permissions for their applications to SharePoint API.

But from this moment – having SharePoint API permissions in MS Graph – in theory – we can fully rely on permissions provided in Azure and – in theory – this should allow us disable SharePoint-Apps only principal:

Set-SPOTenant -DisableCustomAppAuthentication $true

My math professor taught me: “before trying to find a solution – ensure the solution exists.” So let us test:

Are we really able to work with a specific SharePoint site using MS Graph and SharePoint API Sites.Selected permissions provided via Microsoft Azure?

What will happen with our new/legacy applications if we disable SharePoint app-only SPNs (DisableCustomAppAuthentication)?

I’m getting controversial test results… maybe PnP.PowerShell 1.10 is not fully support SharePoint Sites.Selected API.

Tech Wizard (Sukhija Vikas) on March 20, 2022 in the article “SharePoint and Graph API APP only permissions for Selected Sites” suggests using pre-release (AllowPrerelease).

So please ignore the following for a while.

Meantime I’ll test providing SharePoint Sites.Selected API permissions via Graph API call.

Findings

PnP.PowerShell Get-, Grant-, Set- and Revoke-PnPAzureADAppSitePermission cmdlets require Azure App with MS Graph Sites.FullControl.All app permissions (otherwise it says “Access denied”) and authentication via certificate (otherwise it says “This cmdlet does not work with a ACS based connection towards SharePoint.”)

The same actions – managing permissions for the client app to the specific site collections – could be done via Microsoft Graph Sites Permissions API using just secret-based authentication.

If an azure app does not have Sites.Selected API permissions configured – “Grant-PnPAzureADAppSitePermission” works as expected – no error messages – the output is normal – as if Sites.Selected API permissions were configured in the app. The same for Get-, -Set and Revoke-. Permissions provided for the app to the site are not effective though: Connect-PnPOnline works well, but all other commands – starting from Get-PnPSite – returns “The remote server returned an error: (403) Forbidden.”

If an app have no permissions to SharePoint – “Connect-PnPOnline” works ok, but “Get-PnPSite” return an error: “The remote server returned an error: (403) Forbidden.”

Set-PnPAzureADAppSitePermission gives an error message “code”:”generalException”,”message”:”General exception while processing”
if the site is not specified.

AppInv is not working?

Error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

Providing Permissions to a Site for Sites.Selected App

How to provide permissions for an Azure registered application with MS Graph SharePoint Sites.Selected API permissions to a specific site via calling Microsoft Graph API from PowerShell.

We need an “admin” application – Azure registered application with with Sites.FullControl.All MS Graph API permissions. This method can use secret, so we need Client Id and Client Secret for this “admin” app.

We also need a Client Id and Application Display Name for an Azure application with Sites.Selected MS Graph and/or SharePoint API permissions provided.

And we need our “target” site Url.

With PowerShell scripts you can:

  1. Get Microsoft Graph Access Token with an “admin” app
  2. Get client (target) site Id
  3. Get current app permissions provided to client site
  4. Add read or write permissions for the client app to the client site
  5. Revoke one specific permission from site
  6. Revoke all app permissions provided to site

Connecting to SharePoint Online programmatically: Secret vs Certificate

Update: Sites.Selected API MS Graph permissions was introduced by Microsoft in 2021. It was a good move towards site-level development, but still developers were limited with only what MS Graph API provides for SharePoint dev.
So devs had to use AppInv.aspx at site level to provide ACS permissions to their apps to be able to use SharePoint CSOM and REST APIs.
Recently Microsoft introduced Sites.Selected SharePoint API permissions for registered Azure Apps! So now devs should be fully happy without ACS-based permissions.

Scenario

You have an application that needs access to Microsoft 365 SharePoint Online site/list/documents. Application is running without interaction with users – e.g. unattended, as daemon job.

There are two options you can authenticate to Microsoft 365 – with the secret or with the certificate. Authenticating with certificate is considered more secure.

Questions

  • What happens if SharePoint-Apps only principal is disabled
    (i.e. ‘set-spotenant -DisableCustomAppAuthentication $true’ )?
  • Why I’m getting 401 error when authenticating to SPO?
  • Why I’m getting 403 error when authenticating to SPO with secret?
  • What permissions to I need to work with SPO?

Findings

Note: we will use PowerShell 7.2 and PnP.PowerShell 1.9 to illustrate it.

Disabled SharePoint-Apps only principal

If SharePoint-Apps only principal is disabled in your tenant
(i.e. ‘Get-PnPTenant | select DisableCustomAppAuthentication’ returns $true ), then the only way you work with SPO from code is:

  • an App registered in Azure
  • API permissions provided via Azure (MS Graph, SharePoint)
  • Certificate is used

In all other cases (even your Connect-PnPOnline command complete successfully) – you will be getting error 401 (unauthorized) when trying Get-PnPTenant or Get-PnPTenantSite or Get-PnPSite

Enabled SharePoint-Apps only principal

If SharePoint-Apps only principals are enabled in your tenant
(i.e. ‘Get-PnPTenant | select DisableCustomAppAuthentication’ returns $false ), then you have three options to work with SPO from code:

  • Azure App with a secret (Client Id + Client Secret) and permissions to SharePoint provided via SharePoint (AppInv.aspx) to access SharePoint REST API
  • Azure App with a certificate (Client Id + Certificate) and permissions provided via Azure to access SharePoint REST API
  • Azure App with a certificate or secret (Client Id + Secret or Certificate) and permissions provided via Azure to access SharePoint via Microsoft Graph API

Get list of new m365 SharePoint sites or teams with PowerShell and Graph API

There are scenarios when you need to pull only newly created SharePoint sites, e.g. get sites created since yesterday or get last 100 created sites. Usually other articles and existing PowerShell scripts solve this by pulling all sites from tenant and then iterating through sites to get only new sites. That approach is not nice and simply does not work in large environments. How can we get only sites created recently, not all sites? Here is how I use Microsoft Graph API to get only new sites.

Update (6/28/2024): Microsoft announced updates to it’s delta API for SharePoint, so I added option 3 – see below.

Scenario

Let say you administer Teams, OneDrive and SharePoint Online in a Microsoft 365 tenant. You have a pretty big environment – ~10k or more sites and you want to quickly find just new SharePoint sites or teams (e.g. sites created recently – during last hour/day/week/month). This might be required for ad-hoc reports and for automation scenarios – like applying required configurations or assign some property value to all newly created sites.

With GUI it’s done easily: SharePoint Admin Center -> Active Sites -> sort based on “Date Created” – done.

With PowerShell – not so simple.
“Get-PnPTenantSite” cmdlet returns a site object but the object does not have “Created” field. It’s a web property (not site property). But to get a web object – you have to connect separately to each site and get root web object to check when the web was created. For small environments it is possible, for large environments it can take days… And still not nice.
“Get-PnPTenantSite” with “-Filter” option would help, but “…Currently, you can filter by these properties: Owner, Template, LockState, Url.”

Get-SPOSite – similar experience.

Teams + Exchange modules can help a little:

Get-Team | select GroupId | % { Get-UnifiedGroup $_.GroupId | select DisplayName, WhenCreated } | sort WhenCreated

but… 1) it’ll give you group-based sites only 2) it is not easy to automate 3) this might take long for large environments. I know much better solution:

Solution

Microsoft Graph API helps. It returns result in seconds and you can sort or filter results based on created date . Below are two methods: Option 1 is based on Search and filtering and Option 2 is based on Sites Search and sorting. So there are some pros and cons for each method.

Option #1: Microsoft Graph Search API.

Entry point: https://graph.microsoft.com/v1.0/search/query

Microsoft Graph Search API allows KQL in queries. So we can form a query with something like “created>=1/1/2021” and use entity type = ‘[“site”]’. Search should return only sites created after Jan 01, 2021.

Check PowerShell script sample here: Get-NewSites.ps1
https://github.com/VladilenK/PowerShell/blob/main/reports/SharePoint/Get-NewSites.ps1

If you are getting more than 500 results – think of paging.

Option #2: Microsoft Graph Sites API

Entry point: https://graph.microsoft.com/v1.0/sites

This option is also based on Microsoft Graph API, but sites entry point, which allows search too and sort results by property “createdDateTime”. So we will just search for everything and select how many results we need based on createdDateTime property.

Check PowerShell script sample here: Get-NewSites.ps1
https://github.com/VladilenK/PowerShell/blob/main/reports/SharePoint/Get-NewSites.ps1

Option #3: Microsoft SharePoint delta API

You can use “Get delta” under SharePoint Graph API – check for details here. It says “Get newly created, updated, or deleted sites without having to perform a full read of the entire sites collection”. I’ll do my own testing, but for now check this:

Retrieve SharePoint Online system page html content programmatically (PowerShell)

How can I get HTML content of a SharePoint online page from code, e.g. PowerShell?

Invoke-WebRequest returns “Sign in to your account” page, not a real page, even with -Token option.

Thanks to Denis Molodtsov, the solution is found. It turns out the “Invoke-PnPSPRestMethod” PnP cmdlet works not only against /api endpoints, but also against site pages and system pages.

But (as per my experience) it works only with PnP.PowerShell and with -UseWebLogin authentication option and with -raw parameter.

Connect-PnPOnline -url $siteUrl -UseWebLogin
Invoke-PnPSPRestMethod -url /_layouts/15/viewlsts.aspx -Raw

Other combination of authentication options ( -interactive, -clientId, -Token, -SPOManagementShell, -PnPManagementShell ) – worked well, but only for /_api endpoints, and gave me “401 UNAUTHORIZED” against system/site pages.
Unattended authentication (with clientId, clientSecret and certificate) – same.

Legacy PnP module SharePointPnPPowerShellOnline did not work at all: “EXCEPTION,PnP.PowerShell.Commands.Admin.InvokeSPRestMethod”.

I tested it with
– SharePointPnPPowerShellOnline v 3.29.2101.0 (under Windows PowerShell 5.1) and
– PnP.PowerShell 1.8.0. (both Windows PowerShell 5.1 and .net core PowerShell 7.1.5)

Search Unified Audit Log Daemon Job

How to run “Search-UnifiedAuditLog” in unattended way, i.e. non-interactive.
What are the minimal permissions required?

The PowerShell code:

$clientId = ""
$cPwd = ConvertTo-SecureString -String "" -AsPlainText -Force

$cPath = ""C:\Users\UserName\Certificates\Cert.pfx""
$organization = "contoso.onmicrosoft.com"

Connect-ExchangeOnline -CertificateFilePath $cPath -CertificatePassword $cPwd -AppID $clientId -Organization $organization

[DateTime]$start = [DateTime]::UtcNow.AddMinutes(-45)
[DateTime]$end = [DateTime]::UtcNow
$resultSize = 1000

$results = $null
$results = Search-UnifiedAuditLog -StartDate $start -EndDate $end -ResultSize $results.Count
$results | Select-Object RecordType, CreationDate, UserIds, Operations -First 3

Disconnect-ExchangeOnline -Confirm:$false

Troubleshooting

The error “The term ‘Search-UnifiedAuditLog’ is not recognized”:

Search-UnifiedAuditLog: C:\scripts\PowerShell.auth\Search-AuditLog-w-App.ps1:16:12
Line |
16 | $results = Search-UnifiedAuditLog -StartDate $start -EndDate $end -Re …
| ~~~~~~
| The term 'Search-UnifiedAuditLog' is not recognized as a name of a cmdlet, function, script file, or executable
| program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

means a proper administrative role (e.g. “Exchange administrator”) is not assigned.

PowerShell Script to Fetch All Alerts from SharePoint Online Site

Microsoft announced SharePoint Alerts retirement. Starting from October 2025 – the SharePoint Alert expiration feature will be gradually activated. In January 2026 Microsoft will turn off creation of new SharePoint Alerts (gradually). In July 2026 the ability to use SharePoint Alerts will be removed.

How do we know how many alerts are configured in our tenant? Can we get a report on all alerts of all users from all tenant SharePoint sites?

Approaches are:

  • use Microsoft 365 Assessment tool (they have a mode to get all alerts – here is the doc)
    Microsoft 365 Assessment tool is a great tool, but it is an .exe software, so in large orgs it might be difficult to use it and it requires admin’s permissions to run
  • use custom PowerShell scripts – this option might help if you
    – need a specific report format/data/columns
    – want to quickly get report on alerts for a specific site or site/user
    – can run the script as a site collection admin/owner (does not require tenant admin permissions)

PnP.PowerShell-based script

You’d just use “Get-PnPAlert” cmdlet. That is it.

It requires connection to a specific site, and it allows to get all alerts for the specific user, all alerts for the specific library and all alerts for all users and all lists/libraries:

Get-PnPAlert -AllUsers

The cmdlet returns an alert object with the following properties: AlertFrequency, AlertTemplateName, AlertTime,AlertType,AllProperties,AlwaysNotify,DeliveryChannels,EventType,Filter,ID,Item,ItemID,List,ListID,ListUrl,Properties,Status,Title,User,UserId,Context,Tag,Path

If you need to get all alerts from all tenant sites – just do the same in a loop. Here is the example:
https://github.com/VladilenK/m365-PowerShell/blob/main/reports/Site/Get-Site-Alerts.PnP.ps1

CSOM-based PowerShell script

This is an old-style CSOM-based script we used before PnP designed their beautiful cmdlet. Notice that what took 20 lines of code PnP implemented in one cmdlet.

PowerShell Script to get All Alerts of all Users from a specific SharePoint Online Site Collection, including subsites:

https://github.com/VladilenK/PowerShell/blob/main/reports/Site/Fetch-All-Alerts-from-SPO-Site.ps1

( raw: https://raw.githubusercontent.com/VladilenK/PowerShell/main/reports/Site/Fetch-All-Alerts-from-SPO-Site.ps1 )

it is based on Salaudeen Rajack’s script:
SharePoint Online: Get All Alerts from a Site Collection using PowerShell
I updated authentication part, so now the script support both MFA and password-only based authentications

Connect to SharePoint Online and MS Graph Interactively with Client App and MSAL token

Scenario

You have a Microsoft 365 subscription with SharePoint Online. You use PowerShell, PnP.PowerShell module and MS Graph API to work with SharePoint under current user’s credential. You need to authenticate to SharePoint Online via Connect-PnPOnline and to Microsoft Graph API interactively on behalf of a current user.

Problem

Unfortunately, both “Connect-PnPOnline -Interactive -Url <siteUrl>” or “Connect-PnPOnline -UseWebLogin -Url <siteUrl>” might fail with something like “Need admin approval”, “App needs permission to access resources in your organization that only an admin can grant. Please ask an admin to grant permission to this app before you can use it.” or “Permissions requested” or similar

Solution

  • register an Azure App. Choose “single tenant”
  • configure authentication blade:
    – add platform – “Mobile and Desktop app”
    select “https://login.microsoftonline.com/common/oauth2/nativeclient”
    add custom Redirect URI: “http://localhost”
  • configure API permissions blade:
    – add delegated permissions you need (refer to specific API you’ll use)
    e.g. Microsoft Graph Sites.FullControl.All and SharePoint AllSites.FullControl
  • use the following code samples

PnP.PowerShell

$siteUrl = "https://contoso.sharepoint.com/teams/myTeamsSite"
$appId = "" # Client Id
Connect-PnPOnline -ClientId $appId -Url $siteUrl -Interactive
Get-PnPSite

A pop-up window will appear to authenticate interactively. If you are already authenticated with another credentials (or single-sigh-on) – an interactive window might pop up and disappear – that prevents you enter your other id.
To ensure Connect-PnPOnline prompts you for your credentials – use ” -ForceAuthentication” option.

If you are a SharePoint tenant admin – you can connect to a tenant with:

$orgName = "yourTenantPrefix" 
$adminUrl = "https://$orgName-admin.sharepoint.com" 
$appId = "" # Client Id 
$connection = Connect-PnPOnline -ClientId $appId -Url $adminUrl -Interactive -ReturnConnection # -ForceAuthentication 
$connection 

Microsoft Graph API

Use MSAL.PS module to get an msal token then use token in Microsoft graph-based requests:

$tenantId = ""
$clientid = ""
$url = ""
$token = Get-MsalToken -ClientId $clientid -TenantId $tenantId -Interactive

By default token expires in ~ 1 hour. But you can refresh it silently.
This helps you in long-running PowerShell scripts that takes hours to complete.
So you can include something like this in the loop:

if ($token.ExpiresOn.LocalDateTime -lt $(get-date).AddMinutes(10)) {    
  $token = Get-MsalToken -ClientId $clientid -TenantId $tenantId -ForceRefresh -Silent    
  Write-Host "Token will expire on:" $token.ExpiresOn.LocalDateTime
}

Application permissions

Somehow using Connect-PnPOnline with AccessToken option did not work if the token was acquired with MSAL.PS interactively. But it did work when you get msal.ps token unattended (using App credentials). So…

If you can get an Application (non Delegated) permissions to your azure-registerd-app,
you can use msal token to connect to site with PnP

=========================

NB: For delegated permissions, the effective permissions of your app are the intersection of the delegated permissions the app has been granted (via consent) and the privileges of the currently signed-in user. Your app can never have more privileges than the signed-in user.

Track SharePoint App-only Service Principals in Microsoft 365

Update (Feb 2025):
A new KBA: Azure ACS retirement: Track down ACS apps

Update (May 2023):
You can use Get-PnPAzureACSPrincipal to returns the lists of all Azure ACS principals installed in your Tenant including subsites.

Update: Sites.Selected API MS Graph permissions was introduced by Microsoft in 2021. It was a good move towards site-level development, but still developers were limited with only what MS Graph API provides for SharePoint dev.
So devs had to use AppInv.aspx at site level to provide ACS permissions to their apps to be able to use SharePoint CSOM and REST APIs.
Recently Microsoft introduced Sites.Selected SharePoint API permissions for registered Azure Apps! So now devs should be fully happy without ACS-based permissions.

Update: I’m not sure when Microsoft implemented that, but I recently found another Record Type – “SharePointAppPermissionOperation”. There is an Activity type – AppPermissionGrant…
To be explored…

After all the updates the original article below is probably obsolete…

Scenario

Developers in the organization can use both – Azure Apps and SharePoint Apps to work with SharePoint sites in their “daemon” applications.

It is recommended to use Azure apps so, you want to know – what are SharePoint Apps registered and their owners, who registered SharePoint Apps. Eventually you would disable SharePoint Apps-only principal but before that you’d move Devs from SP-App-only to Azure App (see Disable Custom App Authentication).

(SharePoint App-only service principals aka SP-App-Only are SPN or App registered from within SharePoint using AppRegNew.aspx system page).

One of the approaches is to track Apps/Owners (or who register an app) with Unified Audit Log

Use Unified Audit Logs

The following PowerShell code:

$operations = 'Add service principal.'
$recordType = 'AzureActiveDirectory'
Search-UnifiedAuditLog -StartDate $start -EndDate $end -ResultSize $resultSize -Formatted -Operations $operations -RecordType $recordType

returns events with operation = ‘Add service principal.’ Nice, but…
if an app was registered in Azure – event contains an UPN under UserIds property:

Unfortunately, in case with registering app in SharePoint, an audit log event will be like:

i.e. UserId registered is “spo_service@support.onmicrosoft.com”, so we do not know who registered a SharePoint-only app

In theory – we could use events recorded immediately before and after “Add service principal” event to track a user and site who has registered a SharePoint-only app… But for me it seems like too complicated for automation.

Instead we can do simple search through audit log for events “AppRegNew.aspx page visited”. This gives us a good approximation of who registered SP-App-only principal. Worst scenario – we reach more people than we really need (including those who started registering sp-app-only but did not complete) but all of them would be definitely our target auditory.

Consider the following code:

$freeText = "appregnew"
$operations = 'PageViewed'
$recordType = 'SharePoint'

$results = Search-UnifiedAuditLog -StartDate $start -EndDate $end -ResultSize $resultSize -FreeText $freeText -Operations $operations -RecordType $recordType 

this would give you all users who loaded “/_layouts/15/appregnew.aspx” page
