We have an issue whereby the MTR does not allow you to join any forwarded external Team meeting invites. The resource mailbox will accept the invite however when you go to the meeting room the JOIN button is not there.
If the invite is sent directly from the external we will be able to join the meeting in the MTR.
We use Crestron Flex. We have changed the settings in Proofpoint so that the URL is not overwritten, enabled the resources to accept/decline external meeting invites however we are still having the same issue.
Any help would be greatly appreciated.

@MJBuxton When I'm using Outlook application and forward to MTR systems I always remove the text in the top of the message since I had the same problem as you a long time ago when I didn't remove this text. I'm not sure if you have to remove that anymore and I rarely use Outlook application (use web app instead) so I can't say for sure.

@Askanison Set-CalendarProcessing -Identity YourResourceMailboxMailid@YourDomain.com -ProcessExternalMeetingMessages $True - It will enable external domain to book your organization's meeting room.

We are having the same issue, we can't join external forwarded meetings.
Did you ever find a solution?

Sorry, never managed to resolve this and the only way round it is to forward the invite via 'Outlook on the Web', which we don't use due to a lack of integration with our other desktop products.

Thank you for your reply, I looked through a lot of forums for a solution and could not find anything that would work, I opened a case with Microsoft, slim chance they will figure it out.
I opened a case with Yealink and they are pointing me to forums, what can I expect for a company based in China.
I will let you know if I find anything that works.

@yeslink I was able to resolve this, I can't recall what the issue was as it was a while back, but I'll check back my notes to see. Most likely it was something in powershell.
I did set it up as a hybrid Exchange, created the MTR accounts as resource accounts, set it to auto respond to requests. The forward must be an actual meeting invite.

@MrSaltyTT It would be really to know what you did, if you're responding to the OP's actual issues.
Processing external calendar invites isn't a problem but invites that have been forwarded on to the equipment/device is where the problems occur. The equipment/device doesn't detect them as Teams meetings so you can't actually join the meeting.

@jameshamilton when you forward an invite to the room, what does the url show in OWA for that room mailbox? Is the URL modified or is it teams.Microsoft.com etc?

@joeyturner I'm about to try this with our environment now and will feedback the results.
