Blank emails

Thank you BDAqua, I tried restarting in Safe Mode but this did not solve the problem.

The blank emails are in local folders On My Mac, not IMAP or POP emails in the Inbox.

Mail appears to corrupt emails that I have moved off the server into local folders.

I've lost some very important older messages.

Thanks, RW

Thanks BDAqua,

I'm afraid it would be much too complicated to restore from Time Machine, as these are individual emails scattered between hundreds of different email folders. And I have no idea how long ago each of them might have become corrupted.

I'm really not sure Apple Mail's database system is robust enough to handle large email archives.

It's a pity, as it's a good programme in other respects. I'm going to try migrating to Outlook, much as it pains me to do so.

Thanks
