IMAP command “UID COPY” (to Deleted Messages) failed for the mailbox.

I got the same message when I tried to delete messages from my AOL inbox in Mail.

My install was an upgrade from 10.4. I have several email accounts set up in Mail. I only tried to delete messages from the AOL one. The others are hosted on Earthlink.

I verified permissions using Disk Utility, but no issues were found.

Any advice?

I get the same issue with Mail since upgrading to Leopard. I can delete email fine via my iPhone and now have to do it that way as Mail in Leopard is kind of buggy. And of course I can delete email via my webmail account. I'm running IMAP mail on a hosted server.

Go to mail Preferences... --> Accounts --> Your IMAP Account --> Mailbox Behavior Tab --> UNCHECK "Move deleted messages to the trash mailbox."

This worked for me. I think Leopard inadvertently turned it on.

I tried that and it didn't do the trick. I'm getting the same message on my IMAP account, but only on the one machine upgraded to Leopard. Can delete mail fine on my old system. Spoke to my ISP and they didn't have any suggestions.

Anybody?

You can create an offline mailbox, move the e-mai into that and then delete. A bit cumbersome but it seems to work.

Except that this worked just fine in mail on tiger. I have all the folders set to server (trash, sent etc). Tiger mail - fine. Leopard mail - warning triangles (folder not found or needs to be subscribed) and deleting gives this error.

It seems that server side sync of IMAP is not as well supported in Mail 3 as it was in the previous version 😟

Setting things local seems to be a useable workaround - but I really hope they fix it for server side too.

I solved the problem for my own IMAP account, proceed at your own risk. ha

I use DreamHost.com for my IMAP server and they have a good Wiki on how to set-up Mail.app for IMAP here http://wiki.dreamhost.com/MacOS_X_Mail10.4

The key was to specify an IMAP Path Prefix as INBOX. This solved the mail delete problem and created some new mailboxes on the mailbox pane on the left of the Mail.app window at the bottom that has my old-messages and Trash.

What I did also via Webmail was to create a sub-folder of my inbox called *Archived Notes* so that I can email myself old notes from my iPhone for safe storage. I just drag-n-drop my old notes from my INBOX to the Archived Notes mailbox in Mail.app then I can delete the note from my iPhone's Notes app.

If I go to my Webmail or iPhone Mail I have my INBOX with the sub-folders: Archived Notes, Deleted Messages, Junk, old-messaqes, Trash. This is all accessible via my mail clients. Keeps my mailbox tidy, gives me access to deleted Notes from my iPhone and things seem to be running fine.

When you do this don't be alarmed when your mail disappears from your inbox in Mail.app as they will reappear as it says in the DreamHost Wiki.

Hope that helps.

Worked for me! Thank you!!

thanks for the solution!

however, i wonder now where the deleted messages go? knowing me, i'm likely to accidentally delete important e-mails.
