Good Morning and Welcome,
To help the admin guys out and to save abit of time could you try 2 things for me....
Go to this website
Outlook Troubleshooting Options - Zimbra :: Wiki
Under the heading Using Logging Control for Troubleshooting run that program located in the \Program files\common files\system\msmapi\1033 directory.
Also if Outlook is being rubbish it should create a core dump of the error both files should be in the same place for windows 7 I think the default location is
C:\Users\Username\AppData\Local\Temp
Try them and if you can post the logs zipping may be best then that saves the admin guys here having to tell you this info.
Cheers
Simon
