Before installing a new OS I tried to backup my Thunderbird by copying the .thunderbird directory.
To be on the safe side I tried to emulate the restore procedure on another machine. I copied the .thunderbird directory to it and set up a symlink from /home/username/.thunderbird to this backup directory.
Thunderbird starts correctly, it shows plugins, calendar, address book, all news feeds and all mail accounts.
But for POP accounts it shows only the Inbox folder (which is empty) and the Trash folder. All the other folders are missing (Archives, Drafts, Sent).
What I have tried so far and it did not help:
- click 'Repair folder' from the menu folder;
- Delete .msf files to force Thunderbird to rebuild index;
- Delete Panacea.dat;
- start Thunderbird with -profilemanager to choose the particular profile directory;
- all tips from the official documentation.
It seems like Thunderbird successfully restores all the information from the backup, except the folders and messages for POP mail accounts.
Any ideas regarding such a strange behavior of Thunderbird?
