128.6.1esr (64-bit) on M1 MacMini, Sequoia 15.3
Mails have disappeared in local folders, I guess since the last update (don't always check if all are still there).
I imported the mailboxes and local folders from Postbox in autumn. Everything was still there.
I used Folder Compare to compare the TB directories with the Time Machine backup immediately after the import and today's status. By and large, all the files are still there, with only minor differences in size.Repairing does not lead to any success! Is my dim memory still correct that this can be solved by deleting the respective *.msf file?
Tested - no success!
More about this in the Thunderbird-Mail forum, it would be tedious to translate the whole process and post it here.
Is there any indication of what could be the cause and what else I should try?
