Setting up a new imap account in Outlook 2010, only account, and connection tests good. But nothing is visible or accessible from any folders. When connecting, it goes through the motions and appears to be checking/downloading. The first time takes a long time as expected, and subsequent Send/receive runs through quickly. All subfolders are created, but all remain empty. Checked for filters and cleared every folder. Mail is still intact on Yahoo, just can't get to it from Outlook.
