Hi

I'm helping a user who uses Outlook 2011 on his new retina-MacBook Pro which is running OS X Yosemite. He has 1 IMAP account setup in Outlook. He can reliably see all IMAP-server based folders. He recently setup some local folders in the "On My Mac" section within Outlook. Consistently, within minutes of opening Outlook all of the sub-fodlers in the On My Mac section will vanish. He isn't touching this folders. He's merely dealing with messages in his Inbox when the sub-folders vanish. The only way he can get the folders to re-appear is to restart Outlook. He has rebuilt his Outlook database and the problem persists. All Office 2011 updates have been installed. Any suggestions?

I know I could export all of the subfolders into a .OLM file and then build a new Identity and import those folders and setup his IMAP account again. I can do this but I wonder if anybody has seen this issue before and/or has any less time-consuming troubleshooting suggestions. Thanks. --Tim
