We have had issues where VScan for Mac has created thousands of duplicate emails in users outlook as stated here:
This was back in September and a KB article existed that said to exclude the following directories:
/Users/.*/Documents/Microsoft User Data/Office 2011Identities/Main Identity
I think that McAfee Kb was
KB75781 · Microsoft Outlook 2011 email duplication when VirusScan for Mac is installed
However, it doesn't exist anymore and i can't find anything on that subjct now.
Does anyone have any idea as to what has happened to the article or if there is any update on this at all?
