THunderbird shows the Folder but its empty. When i store my Local Folders on a local drive all works fine. Reproducible: Always Steps to Reproduce: 1. Local Folder are stored on a network drive. 2. Create new Local Folder 3. Move mails from imap folder to local folder 4. restart thunderbird 5. reconnect to imap server Actual Results: All mails i moved to the newly created local folder are lost. Expected Results: Mails should be there. I found out that in the 'Local Folders' Dirctory an entry named like the newly created folder exists, but it will be deleted after i restart thunderbird and connect to the imap server.

I believe this is long fixed. but reporter is gone/no response, so closing incomplete.
