Enable calendar feature in CX600 UC Phone in Lync environment

Question

I have CX600 and CX3000 up and running in a Lync environment. Calls between CX UC Phones and Lync clients are working fine and also the Unified Messaging feature as well. Now, I want to get also the Calendar feature enabled. Is there any additional configurations to be done in Lync or in Exchange 2010 side to get the Calendar feature enabled for CX600 and CX3000 UC Phones ?

Thanks. Brahim. 

Answer 1

Same Question for the AAStra Phones ;-)

Answer 2

I'll bet that you forgot or didn't enable the user for UM in exchange.  That's what fixed it for a couple of users in our setup.

Exchange UM is not required for Calendar integration, although it is needed for Call Log integration: http://social.technet.microsoft.com/Forums/en-PH/ocsucintegration/thread/65a720a5-7c57-42e7-af2f-990d0d1a6f69
