I have a user (my CEO of course) whose subfolders of his outlook inbox are disappearing. Email that is in his inbox is fine and none are missing, it is only the subfolders within the inbox that are disappearing. It is approximately 3 dozen subfolders that go missing.
He has a laptop with Outlook 2007 connecting to an Exchange 2010 server. Auto archive had been configured but is no longer turned on when we examine the only MS outlook he is configured to use. He uses the laptop sparingly and never removes if from the dock. When the first round of missing email folders occurred we checked the archives but it was not there, or anywhere we could find. we turned the auto archive off and the folders have gone missing 2 more times.
The CEO prefers his iPad 2 and iPhone 4s (both on iOS ver 5.0.1) as his daily tools. He travels often and is rarely on his laptop in comparison to the iPad and iPhone. The CEO's assistant has a MAC (lion OS) book Pro with Mac Mail and Outlook for MAC 2011. She is in his email all day as well as hers. She has had no mail loss we can find so we do not believe that these are the issue but are open to check potential issues.
To complicate things we recently upgraded to Exchange 2010 from 2003 and moved the CEO's assistant to a MAC book Pro from windows XP within 2 weeks of each other. It was after the upgrade and desktop move both happened we noticed the missing folders. So it could be that either, both or neither are contributing to the problem.
We are stumped. We cannot find where the email is going or why. Does anyone have any ideas? Thanks in Advance.
