My messages have become mixed up.

Messages have switched contents.  message bodies from other messages have jumped around.  Very strange.  Did a repair but that didn’t help.

IMAP account.  Gmail online is fine. Very strange.

Hi Paul, what version of eM Client are you currently using on your computer?
Repairing the mail folder should work in this case, as we had an issue that may have caused this, try to update your eM Client to this release and use the repair feature for a selected folder and check if the issue persists.

Thank you,
