Get list of new SPO sites with PowerShell

Scenario

Let say you administer Microsoft 365 SharePoint Online and you want to get a list of new SharePoint sites (e.g. sites created recently – during last day/week/month).

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. 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.

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

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.

Yammer API with PowerShell: Private groups and messages

As an Office 365 administrator, I would like to get some reports on Yammer with PowerShell. How it’s done?

Patrick Lamber wrote a good article here: “Access the Yammer REST API through PowerShell“. The only I would add (important!) is:

By default, even with a Verified Admin token, you do not have access to private messages and private groups content.
To get private stuff, you need select “Private Content Mode” under Yammer Admin Center -> Content and Security -> Content Mode:

Check Microsoft: “Monitor private content in Yammer” and
Yammer: “Verified Admin Private Content Mode

If you do not have “Private Content Mode” set up, you might see some weird “Invoke-WebRequest” errors like:
