Fixing “The Message Could Not Be Moved to the Mailbox Trash” Error on a Mac

[Updated 11/3/17]

If you have run into the following message in Mail on your Mac, Macbook, or Macbook Air: “The message could not be moved to the mailbox ‘Trash'” (or some other mailbox) “The message *.emlx couldn’t be copied to ‘Messages’ because an item with the same name already exists,” here is what to do to fix it.

We most often see this when someone is trying to delete a message (move it to the Trash folder), but it can happen in other situations as well. A reason that you might run into the “The message could not be moved to the mailbox ‘Trash'” situation specifically seems to be when you try to delete a huge number of messages at once, which may for some reason corrupt the trash folder.

I first transferred all the “good” messages in the In Box to a temp mailbox, leaving the three bad ones, then rebuilt the in box, at which point the bad ones disappeared.

  11. This didn’t work for me! I’m getting spam pieces that seem to have an attachment. When I try to move them, I get: The message “STEVE, Notice to appear in Court #000871089” could not be moved to the mailbox “Junk — stevecagan” / The file “145392.emlx” couldn’t be opened because there is no such file.” Rebuilding the mailbox I want to send it to doesn’t help at all. Sometimes rebuilding the mailbox it’s in helps, but I’m reluctant to keep rebuilding my inbox…

  12. When I try to deleted a mail i get the following msg :

    The file “157321.emlx” couldn’t be opened because there is no such file.

    Please can you help me.

    Thanks!

  13. Yes! Worked for spam/virus e-mails with hidden attachments – i.e.:

    “The message “X” could not be moved to the mailbox Trash – the file “Y” couldn’t be opened because there is no such file.”

  14. Thank you. This works and It saved me. The problem was really aggravating. Much appreciated.

  15. I’m trying to back up my sent my moving it to a folder on my mac in apple mail. When I try to move the nearly 3,000 emails, I get the same error message as you mentioned… However rebuilding doesn’t work. Any other ideas?

    1. Hi Kim! Try moving fewer messages at a time; in fact try moving just a few (like, 3) and if that works, then the problem is that your system can’t process 3k at once, so you’ll need to do it in batches.
