Mail.app archive button stopped working

[hvanzile]

A few days ago the Archive button in Mail.app stopped working. Has anyone else had this happen or have any idea how I might troubleshoot this?

A bit more detail:

• I have Mail.app set up with two accounts - one Gmail IMAP account and one other IMAP account. This problem happens with both of them.
• Highlighting a message in the message list and clicking the Archive button does nothing. Ditto with ctrl-clicking the message and choosing "Archive" from the context menu;
• HOWEVER, opening the message in its own window and clicking the Archive button from the message's toolbar works fine (I added it to that menu bar)
• This morning I completely reset Mail.app (deleted the /Library/Mail/V2 folder) and re-added my accounts. The Archive button functioned normally for a little while after that, but has since returned to being non-functional
• The only third-party Mail plugin I'm running is Mail Unread Menu (http://loganrockmore.com/MailUnreadMenu/). I've tried disabling that and it doesn't seem to make any difference.
• All the other toolbar buttons are working fine - delete, reply, etc.

I'm wondering if this is a problem in 10.7.2? Apologies if anyone else posted about this, but I haven't been able to find anything about it here or using Google.

My system:
Macbook 2.16, 2 GB RAM, Mac OS X 10.7.2, Mail.app version 5.1

Thank you for any help or ideas!

I should add that quitting and re-opening Mail has no effect, nor does restarting the computer.

I had the same problem, and found your post while looking for an answer. Removing MailUnreadMenu worked for me.

Im using "Got Mail?" from the app store as replacement for MailUnreadMenu.
Hope it works for you!

Thanks, Coden! That worked for me, too. I had thought I'd tried disabling it, but I guess I didn't uninstall it completely.

Thanks again!

I am the developer of Mail Unread Menu and I can confirm that version 3.3 of the application caused problems with the Archive functionality in Mail. I've just released a bugfix update, version 3.3.1, that fixes this issue, so the Archive button should be fixed again. Sorry about that!

I can verify that the new version of Mail Unread Menu doesn't disrupt the Archive button. Thanks, Logan!
