Maybe TB broke its cache after the change.

Disable "Server supports folders that contain sub-folders and messages" setting. https://bugzilla.mozilla.org/show_bug.cgi?id=284933 UW-IMAP has this exact same problem, so I don't know why it wouldn't have happened with it (unless TB has some special UW-IMAP checking code). > 2) When switching an Apple Mail.app user running on Mac OS X > 10.4.11 (Tiger) at the > latest patch level, things appeared to work fine, and then > the user mentioned that > no mail was showing up in her inbox.
