How can we know which email address the external user used to register inside the office 365
From time to time we received many emails from external users that they received the following error when they try to sign-in to our sharepoint sites:- but when i check their usernames i ca...
ChrisWebbTechi do not think the user is sign-in with another account, as from the error message it says "we are sorry, but *** can not be found in ***" .. and from the error message it is referring to the correct username (***)!!! and if the email address shown in the admin center's guest account, is the account that need to be used and it is the same as the account showing in the error message, then there is something weird... as the account is already registered as a guest account + added inside the members sharepoint group, so why the user is getting that his email address can not be found "user not in directory"!! while it is found in the Guest user list and inside the SharePoint members group..
It’s very possible that they are logged into the same email account used in office 365 AND their personal account. Seen this numerous times since you could associate MSA with any email in the past. If they are logged into their 365 account thinking it’s the same when it could be expecting their personal account or code Versa. In portal.azure.com ad and users you can see the guest and the source account if it’s their 365 or personal Microsoft account that was used.
