i have a couple of test external Office 365 accounts that i keep using for various test sharing scenarios. this one is an Outlook.com account (not an O365). I’m testing sharing permissions for external users. So as usual when the external user accepts the invitation O365 creates the #ext# user. So wanted to reset the sharing by deleting the that user #ext# user account. after deleting it and trying to re-sharing using the outlook.com account i get the error:
How do i purge the external user account from O365
According to the error, it seems that the user is removed from the Office 365 admin center but is still present in SharePoint Online. When a user browses to a SharePoint Online site, their user information is cached in the UserInfo list. When the same user is removed from the Office 365 admin center, their related UserInfo information is not removed. To resolve the issue, please follow the steps in the article below to remove the user from SharePoint Online.
