She has no filters et al applied to any of these folders where this happens, still she cannot see any emails in them. The error console doesn't show anything. Looking in the file system for one of this folders, the associated files and folder are there: $ cd ~/Library/Thunderbird/Profiles/iq8yxwsu.default/Mail/Local\ Folders\Freunde.sbd $ $ ls -la Katja\ M.* -rw------- 1 marlen admin 8047361 Dec 24 09:29 Katja M. -rw-r--r-- 1 marlen admin 11675 Apr 13 13:19 Katja M..msf Katja M..sbd: total 0 drwxr-xr-x 2 marlen admin 68 Sep 5 2006 . drwxr-xr-x 35 marlen admin 1190 Jun 2 23:14 .. I deleted all .msf index files in this folder (as I remember that there are sometimes problems with mail display with the mbox format and these usually go away if one removes the index files by hand and lets Thunderbird re-create them) and restarted Thunderbird. Suddenly a completly new mbox and index file was created in the filesystem, without any further action: -rw-r--r-- 1 marlen admin 0B Jun 2 23:46 Katja Mf8b8aab7 -rw-r--r-- 1 marlen admin 1K Jun 2 23:46 Katja Mf8b8aab7.msf The mails in the original folder are still not shown, however. If Thunderbird is restarted another time, the newly created (empty) "Katja Mf8b8aab7" mbox is shown in Thunderbirds tree pane as another instance of the "Katja M." folder (apparently it uses the same naming) and is empty as well. So I'm basically having two problems here: a) Thunderbird mail folders which tend to duplicate themselves with suspicious new mbox files b) Still no mail display for the original (faulty) folders Sorry if this is a dupe of something else, but I was completly unable to give proper keywords for a dupe search. Thanks in advance for your support. Thomas. Reproducible: Always Steps to Reproduce: 1. 2. 3.

(Recovery procedure) 1. Rename "Katja M."/"Katja M..msf"/"Katja M..sbd" (say Backup) 2. Delete Mf8b8aab7/Mf8b8aab7.msf (current mail folder files for "Katja M.") 3. Restart Thunderbird => Mail folder of "Backup" will appear. You can change folder name "Katja M." again now, but please note that file name of "Katja Mf8b8aab7" is used(by current design).
