I just installed the Microsoft Office 2011 14.1.3 Update, and now my Outlook won’t launch. Here’s a bit of the text from the error report:
Process: Microsoft Outlook 
Path: /Applications/Microsoft Office 2011/Microsoft Outlook.app/Contents/MacOS/Microsoft Outlook
Version: 14.1.3 (14.1.3)
Build Info: Unknown-110805~0
Code Type: X86 (Native)
Parent Process: launchd 
Date/Time: 2011-09-14 10:30:30.736 -0500
OS Version: Mac OS X 10.6.8 (10K549)
After installing the update, no matter what I did, Outlook would not launch at all. A friend of mine deleted his outlook account and was able to launch outllook. I tried that, and had no luck.
I deleted my “Main Identity” folder and no joy with that either.
I repaired permissions, but that didn’t change anything.
What did work, was going into my Time Machine backups and restoring a previous version of Office. Before doing that, I had to delete my MS Office folder first, and then restored from backup.
I just thought I’d share my results with you, in case you run into similar issues.
I installed the update because it was supposed to fix some issues with my Outlook. Now, I think I’ll wait for the 14.1.4 update or something along those lines.
I should also mention, that none of the other applications in Office were affected. I was still able to launch Word, Excel etc. and use them without a problem. Only Outlook, the one application that I use all the time, was affected.
