Deleted emails not in Trash folder

Hi messymary,

For help with recovering deleted messages you may need to rebuild the mailbox. While the user guide only goes back to macOS High Sierra, the steps in the links below may help.

Rebuild mailboxes in Mail on Mac - Apple Support

Delete emails in Mail on Mac - Apple Support

If the steps don't work test searching for your user guide with the information here: Find the user guide for your Mac

If you backup to Time Machine you can also test recovering the information with the help of the steps here: Restore items backed up with Time Machine on Mac - Apple Support

Cheers.

Understood messymary,

If they have not been deleted from Trash itself, then you may be able to recover them. Check out the steps outlined at Use iCloud.com to restore and recover iCloud information - Apple Support and see if you can still access the messages in question to restore them. If they are no longer in the recently deleted, then they will not be able to be recovered.

Take care!
