Cannot find a summary view of what each External Users have acces to various SharePoint sites
There's no way to capture all the SharePoint sites an external user have access to. There are times these external users are long time company partners or short period contractors who need provision access to a certain SharePoint site or another SharePoint site at different time. Beside deleting their user profiles in SharePoint Admin, there is a possibility of deleting their profiles in Azure as part of the deletion process.
This can be done through PowerShell but it would be nice to have a report showing all external access by organisation and user.
