Our environment consists of 60 windows 7 professional user workstations all using Outlook 2013 (v15.0.4971.1000) 32-bit. We have 2 Exchange servers both are Enterprise v15.0 (Build 1156.6) 64-bit.
All workstations are using exactly the same configurations for Outlook as these are being locked down by GPO.
All users are experiencing an issue where when they send or reply to an email to one particular user in the company, Outlook will crash. Any other user they send an email to works fine. It’s just this one users email address who is causing a problem.
Up until 2 weeks ago all users were using Outlook 2010 on their workstations and were experiencing the same issue. We figured that the upgrade to Outlook 2013 would resolve this problem, but after updating everyone we realized this was not the case. As the issue remains in Outlook 2013 for this individual.
We have been able to get around the issue by instructing our users to delete the cache for that one particular user each time and typing the email address in manually and then the email will send without issue to that user. But they must do this each time as the cache is saved again once the email sends to that user.
We have attempted to delete all cache with no change to the issue. Even a newly built machine with a fresh copy of Office 2013 experiances the issue.
The email address for this user works when it’s is typed in manually, it seems that the cache of this particular address is not caching properly causing Outlook to crash.
This particular user is experiencing no issues whatsoever while using outlook to send and receive emails. However if she sends an email to herself using her cached email address, Outlook will crash, if she types it in manually after deleting the cache as seen above, she will receive the email without issue.
Disabling the cache altogether for users is not an option.
Is there a way to fix this without disturbing the mailbox for this user or recreating the account?
