ve a weird issue happening. A user reported that their Lync conversation history stopped working, but they still have the appropriate settings in Lync for conversation history. None of the users conversation history would show up in Outlook, Lync,
or Webmail.

This issue persisted UNTIL I moved their mailbox database to another server. Instantly the all conversation history was restored and was available. Is it possible that there is a bug or configuration on the mailbox database server that would/could
induce this type of behavior?

I'm running Exchange 2010 SP2, the user is running Outlook 2010 and Lync 2010. The mailbox database is a member of a DAG so I just simply changed the active copy of the mailbox and BAM the issue instantly resolved itself. If I change the active
mailbox database back the issue comes back!

Has anyone seen anything like this? Have any ideas?

Thanks,

--Shaun

Hi
I just talk with your case with our lync colleague.
It seems to be user mailbox problem. The situation is to recreate mailbox or move this mailbox to another database. Maybe you can try move it to another database and move it back again.Terence Yu
