My only option is to contact MS Support and have them offer all of the suggestions again but from what Im reading all over is that this is a bug in Outlook that MS is not going to fix. Since my configuration does not take into account Public Folders. If anyone has any further suggestions, please let me know. Otherwise I will look for procedures to DOWNGRADE back to Office 2. Its really sad that MS just throws away functionality that they built, trying to force you to. Public Folders have been around for more than 1. Ok, it appears I have SOLVED this issue for my particular users setup. Ill list all the steps I took to get to a resolution and Ill also list what I believe that actual problem was. First, I reviewed this users setup again, including all archived email, public folder displays and mailbox settings. Here is his setup Exchange Server account Exchange 2. Cached Mode Mailbox is 7. MB in size, email is archived once its 6 months old and moved to archive. Calendar, Tasks, Notes, etc. Archived email stored in 3 PST files, 7. GB in main, 4. 9 in 2nd and 1. GB in a 3rd.   Main archive was stored in the Outlook folder archive. A 2nd Exchange Server mailbox opens that also contains old email from many years ago. This was an old solution as Outlook 2. PST files so we setup a mailbox that could be used to store really old. I believe is the key Archive files were stored on 2 different drives. C drive for the main archive and a second drive for the others. User had been upgraded from Outlook 2. User has Public Folders displayed this was noted to be a cause of the bug because MS deprecated them in Exchange 2. Heres the steps I took to resolve the problem, although I think only one step was needed. Note this is after I attempted the steps above of opening in Safe Mode, disabling Add ons, running the resetnavpane switch, etc and checking for the registry. Shared. Mem. Size 1. Opened Outlook and closed each of the archive files. Closed Outlook. Opened up the Mail utility from Control Panel and ran the Compact utility on each of the archive files. This reduced 3. 4 GB of space. Ran the Scanpst. exe utility on each of the archive files, fixing a number of errors in each. Office 1. 4 folder4. Using the Mail utility again to change settings for the mailbox, I removed the 2nd mailbox from the account. LOT of sub folders and if its being synchronized, this would create a number of connections. The number of connections seems to be a major cause of this bug, as those with a lot of Public Folders that also sync experience this issue. Once this was done, I opened up Outlook. With all of the archives closed and the 2nd mailbox closed I eliminated any other connections to the server except the main mailbox any possible memory issues using 1. GB of archived email. Outlook was now running normally with no sign of the bug  So one at a time, I opened up the archive files again. After each one, I browsed through folders and opened up emails to see if the bug would reappear, it did not. After opening. I was able to use Outlook normally for more than 2. I did NOT open the 2nd mailbox and I firmly believe that the 2nd mailbox was causing this problem to appear. Previously the bug would appear after only a few minutes of using Outlook, but without the 2nd mailbox, there were no issues and there continue to be no issues. Problem solved. So now I am exporting email from that 2nd mailbox and created a 4th archive file and will advise the user to open and close it only when needed. I hope this helps someone else and shows that the bug seems to be caused by connections to the Exchange Server, whether it hits a limit or overloads some kind of buffer, Im not sure, but this definitely is the cause.
