is there any possiblity to get a report of the users in other Office 365 tenants with whom our users have been communicating. This is not about guest access to teams but federated (chat/voice) commnucation.
The answer in this thread is quite stale: https://social.technet.microsoft.com/Forums/en-US/189b746f-b6b7-4857-aa45-cc1c074eccc3/report-on-teams-external-user-communication?forum=msteams
and not really handy to use.
I appreciate any suggestion on this.
