Error "Group has not been applied to the SharePoint Document Library" when running New Collaborate Status Check
Issue
When using the New Collaborate Status Check the following error message is displayed:
Microsoft Group not applied to the Document Library. Click Fix to resolve.
Cause
This error is typically caused when a SharePoint Administrator has made changes to the access permissions for the group directly in SharePoint, or the group cannot be found.
Solution
Step 1 - Add the OneDrive Admin user as a Site Owner
You will need to add the OneDrive Admin as a site owner. Refer to the Microsoft article Manage site admins.
Step 2 - Run the New Collaborate Status Check
Use the New Collaborate Status Check tool. When the Status Check identifies the Microsoft Group is not present, the user can click the Fix button to apply the correct group to the SharePoint site.
