You will also get the update if you disable/enable "show me as in a meeting" option from CUPC. 

This might be a firewall issue.

Whenever there's a calendar update, Exchage mailbox server needs to send UDP packets to CUPS on port 50020.  You may do a packet capture on mailbox server and CUPS to see if something was blocking that port.
