Had a customer call in today who was unable to search a mailbox by week. We discovered that it worked on Monday December 7, 2015 but not on Thursday. Also that the machine was restarted on Wednesday morning. “Patch Tuesday” came to mind.
Their office administrator found a link on the web that matched our symptoms of:
- Unable to search
- Outlook running in safe mode.
We removed “KB3114409” update and the problem was solved.
I hope this helps someone else out there…
