We received frequent Lync limited functionality error for few user .
We observed below event on the Lync server when issue occurred every time.
Event id - 32112,32068,32113,52013,52012
Also same time we observed event id 833 on the SQL server for I/O issue on Temp DB.
We also notice when we recieved 833 event on the SQL same time we recieved event 32068 on the Lync front end server.
Just wanted to Know is there any logging i can enabled on the Lync frontend server to capture this issue to get more clue to resolved the issue.
Lync server 2010 enterprise edition
SQL server 2008
Client mixture of 2010 and 2013
