Hello everyone,
has anyone successfully integrated CUCM 7.1.3 with Exchange 2016 UM ?
We are able to call the subscriber number and dial user mailbox extension but when CUCM hands-over the call to the user's voice-mailbox it fails to match the extension with UM mailbox.
We can hear the following message "Sorry the person you are trying to reach does not have a valid voice mailbox on our system”
I can assure that the test user the proper extension and dialplan.
Best Regards
