Outlook 2010 (with latest updates) hangs while getting new messages or attempting to delete messages (with auto-send/rcv turned off). Here's what I've tried so far (with no success):
- chkdsk /f - no errors found - retried Outlook - same failure
- MBAM (MalwareBytes) - no malware found - fail
- scanpst (only minor inconsistencies found and fixed) - fail
- outlook /safe - fail
- repair Office 2010
- reverts to original RTM - never prompts for updates (tried manually running Windows Update, but no updates found) ??!!
- copy outlook.pst file to other computer
- Outlook 2013 hung on the other computer, but eventually an error message appears stating that the PST is in the old 97-2002 PST format and has reached max size (2gb)
- imported the problem PST into a new PST file - now able to manage folders and delete items from any folder
- Outlook 2013 hung on the other computer, but eventually an error message appears stating that the PST is in the old 97-2002 PST format and has reached max size (2gb)
- copy new PST file back to the original problem computer and open Outlook - fail
- create new profile and use this PST file - fail
