I have a staff person who is collaborating with people who are not on staff. She’s been sharing O365 SharePoint documents and folders successfully for a long time. She successfully shared a particular document with someone but suddenly the person she shared with is getting the following error:
“That didn’t work. We’re sorry, but email@example.com can’t be found in the sharepoint.com directory”
I would have assumed an account for the external user in the form of: username_gmail.com#EXTfirstname.lastname@example.org would have been created. but it didn't. I see lots of other user names in that form.
