Hi there,
I've gone through all the steps as documented here:
https://ahandyblog.wordpress.com/cloud-technologies/office-365-unified-messaging-with-lync-2013-on-premise/
All facets of my Lync 2013 environment and hybrid Exchange environment are working properly -- with the exception of transferring calls from our on-premise autoattendant to a user whose mailbox has been migrated to Exchange Online. The call immediately fails when the 5 digit extension is dialed(it works for everyone else).
On the CAS that fielded the call, I see these two events for each failure:

Any suggestions? I've scoured the web for the right direction on this one but I'm out of ideas.
Thanks in advance,
