Hello,
we have "Teams Room Systems".
After setting up i get the error "can not fetch calendar" on system.
We are using Exchange Hybrid. On premise we have exchange 2010.
The mailbox for the Room system is on Exchange online.
Is Exchange 2010 not supported?
Regards

@Linus Cansby That statement is surprising to me because on-premises autodiscover would simply refer the MTR (after the initial HTTP POST) to Office 365 autodiscover, at which point authentication would occur, and then full supported connection to EWS services against the EXO mailbox. I fully agree that EWS on Ex2010 is not supported but I've never seen a statement that says autodiscover wouldn't work - especially to refer you to a higher version of Exchange. Do you have an authoritative URL that states that Ex2010 not supported for autodiscover with MTR?
@Marc Mönnikes You should look at the MTR logs, event logs, and if needed, watch the network traffic to get a better handle on the issue. This could be a failure in multiple places:

@rovert506 Depends what you think is an authoritative URL. But this statement is from Microsoft:
"Microsoft Teams Rooms doesn't support Exchange AutoDiscover redirects via Exchange 2010."

@Marc Mönnikes You can test to add a autodiscover record in the MTR localhost file. Check a IP for

@Linus Cansby HA - indeed, I see the entry at the very bottom. Thanks for the reference.

Hello,
first of all, "thank you" to everyone who joined the discussion with tips and tricks.
Today i have used a dedicated DNS server (internal) for the device.
On this server i have created a cname entry for autodiscover.domainname.com to the outlook 365 autodiscover server.
So my exchange server is not used.
Similar as the idea to add IP adress to host file.
Now, the device shows no error.
Exchange 2010 seems not to be supported.
It is really hard to find this information.
Tomorrow i will do some tests with the device.
Hope, the workaround will help until we migrate to exchange 2016
Thank you
Regards
