I have set up Outlook to sort incoming mail into 7 different InBoxes based on which one of 7 different email accounts the sender addressed the message to. In Outlook 2010, the default arrangement of folders is alphabetical except for "InBox," Drafts, Sent Items, and Deleted Items, which are displayed at the top of the list. You are unable to arrange folders into any other order. My user-configured in-boxes are displayed in alphabetical order except when a new message arrives. Then Outlook moves that in-box to the bottom of the list. Emptying the in-box and restarting Outlook puts things back in order. Microsoft Tech Support has no idea how to fix this. I have disabled all add-ins (9 of them) one at a time to see if that would fix it. MS Support was sure this was the issue (they didn't like the YouSendIt add-in). This didn't help and all add-ins are re-enabled. Has anyone experienced this problem? And have you found a solution? This is just an annoyance. Every morning when I fire up Outlook, I have to go looking for where my InBoxes have been moved to.
