This article is for SharePoint or Microsoft 365 admins focusing on governance and information protection. If you have SharePoint Advanced Management (SAM) – aka SharePoint Premium licensed or you got at least one Copilot for Microsoft 365 license (as having m365 Copilot license automatically enables SharePoint Advanced Management in tenant), then under reports – Data access governance (in SharePoint admin center) – you can not only get Content shared with ‘Everyone except external users’ (EEEU) reports, but also initiate access review. Let us look more closely at this functionality and discuss the pros and cons..
I’ll not repeat Microsoft documents:
– SharePoint Advanced Management
– Content shared with ‘Everyone except external users’ (EEEU) reports
– Site access reviews for Data access governance reports
but I’ll focus on what is not there and a real-world experience.
Reports and emails
You can share content with EEEU or directly – by adding EEEU to resource permissions directly or by including EEEU into SharePoint group. So content shared with EEEU reports come in two flavors – “Specific files, folders and lists” and “Site membership”

“Specific files, folders and lists” user experience
When you initiate access review from the “Specific files, folders and lists” type of report – users (site admins/owners) get email notification that says “You have sites with specific files, folders or lists shared with ‘Everyone except external users’. This means everyone in your organization has access to this content. Review the items shared for potential oversharing and manage their access.“
Scrolling down, in the email, site owner can see a list (table) of incompliant sites with the following columns: Site name, privacy, sensitivity, external sharing and “Items shared”. Site name is clickable and sends user to the root of the site.
Below the list of sites there is a button “View shared items” that sends user to the special system page –
“https://orgname.sharepoint.com/teams/site01/_layouts/15/siteaccessreview.aspx/<id>” where he/she can see list of SharePoint items shared with EEEU. Columns are: (item) Name, Shared on (date), Shared by (email), Action (manage access). Item name and manage access are clickable.
If item is a library item – e.g. document – it is displayed correctly – with icon according to the doc type and doc name. Clickin on the doc name – an actual document opens so you can review it’s content.
If item is a list item – it is displayed incorrectly – no icon, no meaningful info about the item (it is displayed as “”). Clicking on the link – a warning icon and message “Can’t preview this file. Open the file or download it to view in your desktop app”. Buttons “Open” and “Download” are there but not helpful as well.
Clicking on “Manage access” opens almost standard “Manage access” dialogue you can have via “manage access” item context menu, but with no “…” more options at the top right:

which makes this dialogue screen useless, as you can only provide additional access to the item or remove all access. You cannot remove EEEU from access without three dots “More options”.
“Stop sharing” literally remove all permissions to the item except owners

By clicking on a group name – admin opens standard SharePoint “People and Group” membership page:
/_layouts/15/people.aspx?MembershipGroupId=X, which is nice.
“Site membership” user experience
In the case with a “Site membership” report, text would be slightly different: “You have sites where ‘Everyone except external users’ has been added to the site membership. This means everyone in your organization has access to this site. Review site permissions for potential oversharing and manage access.“, which makes sense.
Right after that, in the email, site owner can see a list of incompliant sites with the following columns: Site name, privacy, sensitivity, external sharing and “Groups with org-wide access”. Site name is clickable and sends user to the root of the site.
Then there is a button “View SharePoint groups” that sends user to the special system page –
“https://orgname.sharepoint.com/teams/site01/_layouts/15/siteaccessreview.aspx/<id>” where he/she can see list of SharePoint groups (clickable) with EEEU as members. By clicking on a group name – admin opens standard SharePoint “People and Group” membership page:
/_layouts/15/people.aspx?MembershipGroupId=X, which is nice.
siteaccessreview.aspx page
User can navigate directly to the reviews page:
“https://orgname.sharepoint.com/teams/site01/_layouts/15/siteaccessreview.aspx” and if there were reviews initiated by SharePoint admins – and it’ll work – admin will see all access reviews initiated for this site – columns are: Review name, Description, Requested on (date), Status, reviewed by (email) and admin comment. In case no reviews were initiated against tie site – “You have no reviews to take action on” will be displayed. That’s good.
GUI only
Once you got report – you can initiate access review. All must be done in GUI, click-click-click selecting sites… But what if you have thousands? There is no PowerShell cmdlets or API for this functionality, which really limits your ability to implement it gracefully, especially in large Microsoft 365 environments and automate it.
Download detailed report
Report “Specific files/folders/lists…” does not include files, folders, list – i.e. it does not include what exactly is shared with EEEU. Report includes site id, url, name, template, is it teams-connected, sensitivity (?), privacy, external sharing, primary admin name and email, and number of items (?) shared with EEEU.
So technically you can communicate to site owners, but you’d need to rely on them to figure out what content is shared with everyone.
Email template
When you initiate Site access review – an e-mail notification is send to site owners. This e-mail is not customizable at all. The only admin can do is to add a message (for every “initiate Site access review” action).
This email comes from “SharePoint Online <no-reply@sharepointonline>” address (not customizable), so comes “from outside of your organization” and can be considered as scam.
Microsoft’s logos and other graphics are blocked by default and e-mail includes a button “View shared items” – enough red flags for users to consider it as spam. Keep this in mind.
The good news is e-mail contains site name – so site owner can recognize it at act accordingly.
Usage scenarios
Small tenants
In small Microsoft 365 environments – yes, this functionality probably can be used “as is” (and should be used).
Medium-size tenants
Depends on your governance rules and company culture.
Enterprises
In large environments, where you probably have a lot of overshared content, I would doubt this functionality is useful “as is”. In enterprises usually all the communication must follow approved templates, dealing with tens of thousands site owners should be automated etc.
