I installed the latest version of outlook for mac about 4 months ago and everything was working very well until yesterday when outlook started crashing. I've tried several fixes that I found in other MS postings like clearing the cache and preferences, creating another identity but the problem still persists. The error message I'm getting is the following:

I have also tried to remove the UBT8T346G9 files from the 'Group Containers' folder but still the same issue. At this point, I would like to either troubleshoot this issue or revert back to Outlook for Mac 2011. The only issue with going back to 2011 is exporting my personal folders from 2015 since the .PST folders I exported 4 months ago are no longer up to date. Apparently, export is not an option in 2015.

Thanks for your help,

Arturo Ochoa
