Teams: Report on external contacts

Hi,

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.
Ben

There's the Teams user activity report in M365 admin centre, which has a filter for unlicensed:

Hi @BenjaminSchowe-2971

If you want to know user activity report for external users, you could try to use Renjones suggestions to check it. But it could not see the detailed chat history from it. For the content of chat history, you still need to use eDiscovery to get it:

But I understand there is no easy method to list the external contacts. I manually have to search through all chat histories?
And there is no method for easily getting the external domains that were contacted by users in my tenant...?

Hi @BenjaminSchowe-2971

Based on communication security considerations, there is no other easy ways to complete your requirements except for the e-discovery search.
