I recently decided to switch my email accounts from POP to IMAP. I figured it would help keep all of my devices in sync so I don't have to read / delete the same messages 4 or 5 times. It seems that was a mistake.
First, Outlook on Windows can't aggregate IMAP accounts into a single Inbox, so I have to manually bounce around and check all of the separate accounts. Outlook on Mac does display the merged accounts in a single Inbox view, but one of my accounts keeps getting stuck in "sync pending" mode, and can't actually get the email until I shut down and restart Outlook.
Do you know what never happened when my email accounts were set up as POP instead of IMAP? There were never corrupt database issues that crashed Outlook, couldn't be repaired by the Outlook Database Utility, and forced me to restore a backup from last week so I can undo the damage.
