Unable to join forwarded External Teams Meetings to MTR
Chris-Yue If it helps, this is the method I used, which works perfectly:
- Administration -> Gateway -> Policies
- Definitions -> URL Protection
- Managed URLs
- Add New Managed URL, with the following settings
- Override Type = Permitted
- Disable rewriting for this entry = Ticked
- Match Type = Domain
- URL(s) = https://teams.microsoft.com/
The PowerShell command is only needed if you want the calendar to be able to auto-accept, via the auto attendant service, invites from external senders and is nothing to do with the problem you're experiencing. It just somehow got mixed up into this thread.
Thanks for the detailed response.
The Mimecast rule is all set up and I can that there is no rewrite when hovering over the Teams Invite link.
The issue for me is as follows where the organiser is external to the Company.
Scenario 1
Before accepting the meeting, the INBOX message invite is forwarded to the Meeting Teams Room (MTR).
The invite is accepted by the MTR and recognised as a Teams Meeting (Teams icon present).
Scenario 2
The INBOX message invite is accepted and an entry appears in the users calendar. The original message in the INBOX disappears.
The meeting invite is forwarded via the calendar entry, but the MTR does not accept the forward and no entry appears on the MTR as a result.
In your environment, do both scenarios work?
