Gmail IMAP does not sync

I've had my IMAP gmail account set up in mail.app for a few months. At first, it worked perfectly -- the two would sync up relatively quickly, both in terms of labeling/deleting email, and noting whether they were read or unread. About a week ago, mail.app started synching right after I would open it -- and then it would eventually label/delete email correctly, but would not change an unread message to read if I left it in my gmail inbox. Now, it isn't even labeling/deleting email -- it won't do anything except right after it is first opened. Manually telling it to synchronize has no effect -- the little clock icon in the account list doesn't even appear. I'm wondering if this has something to do with the 10.5.6 update -- after which, I did run the stand alone Mail update, hoping it would resolve this behavior (even though I wasn't having stability problems) -- but it didn't. Any ideas?

Late 2008 MacBook Pro, Mac OS X (10.5.6)

Me as well. Recently, after upgrading to 10.5.7, my Google Apps IMAP - Apple Mail system has gone crazy. Before, with 10.5.6, the problem was that Apple Mail wouldn't quit -- which was easily solved by doing a forced quit. Now, with 10.5.7 the problem is worse. Now, Apple Mail won't sync with GApps IMAP.

e.g. when I delete an email in Apple Mail, that same email refuses to delete from Gmail IMAP. I go into GApps's webmail, and that email is still there.

I've ensured that, in Apple Mail's preferences, it deletes the trash when quitting -- but quitting out of Apple Mail doesn't cause the deleted email to also be deleted in GApps IMAP.

This wasn't like this before.

It is a real nightmare because I rely on Apple Mail and Google Apps IMAP for my work.

Ok, I can hear the chorus of you saying don't rely on a free email service for work email, but where can I find 6GB of IMAP storage at an affordable price?

Here's what worked for me:

I went an in the left hand column in the "Mail" main screen (the one that shows "Mailboxes, Reminders, On My Mac, etc").

Select the [Gmail]All Mail label in your account. Then go to the menubar (the same one that has the apple logo, "Mail", etc) and select "Mailbox" dropdown.

Then go down to the bottom where it says "Use this mailbox for" and select Trash.

The one caveat would be to be sure in your Account settings you dont have it set to purge your trash box (ie, Permanently erases messages when: NEVER delete) as it could wipe your All Mail.

No promises on if it works for you/messes your stuff up!

Upgrading to Snow Leopard has fixed this issue for me too, albeit not instant - the unread marks now sync correctly each time mail performs a check for new mail.

Not too happy that a complete OS upgrade was required just to get my unread marks to sync, but I will count my blessings that a major frustration in my life has finally been removed!

If you can upgrade to 10.6 then I strongly suggest you do. (ps. just updated to 10.6.1 and still works!)
