One folder corrupt; cannot repair

Every year in January I make a folder in which I store all mails of previous year. The '2024' folder is suddenly corrupt, and I cannot repair it with 'Properties/Repair Folder'. I removed the .msf file after closing TB, but that didn't help either. The entries are still there, but all detail info (title, sender, etc) is missing. Most content contains the text '--=-d6r3+c62j1XS/RY5PVsICg==--'. I viewed the database in a text editor, and a lot of relevant info seems to be still present (hard to check completeness however). All other folders are still OK. And a week ago I was able to access the folder without problems.

Any avise? Thanks, Rob

You might try this tool: https://www.mailsware.com/mbox-repair.html - but I would first try the importexporttools addon to see if it will import the mbox to Local Folders.
