I'm having a problem creating domain filtered user views which looks like a bug and would be interested to see if anyone else has the issue. I'm seeing it on two differenttenants at the moment.
I have 3 vanity domains added to my tenant, 1 of which is federated for single sign-on. If I create a custom user view for the vanity domains, the filter views work fine and only display the users in those domains.
If however I create a view for the default on-microsoft domain it includes users from the Federated domain. This presents a problem as I need to build this view for a client to enable them to easily view when cloud accounts have been created.
