I recently set up Mail.app for Gmail using IMAP. Since then I've noticed that my inbox in Mail.app and in Gmail on the web is always out of sync. For example, I have one message listed in my inbox in Mail.app right now, and there are eight still in the inbox in Gmail. Also, I have several folders in Mail.app (corresponding to labels in Gmail). When I move a message from the inbox in Mail.app to one of these folders, and then try searching for it 30 minutes later, it doesn't appear in the folder or anywhere in Mail.app. If I go to Gmail on the web an search for it, however, it shows up there. The irony of it all is that I finally decided not to renew my MobileMe subscription and switch over to Gmail. I'm beginning to regret that decision. Is anyone else having these problems? If not, maybe it has something to do with my configuration?
