Multiple Copies of Emails

I too have duplicate issues with the Mail App. I'm using exchange 2008 with Intermedia.net for mail, ical, and address book. the dupes happe some days more than others. my iphone syncs via exchange service to the same mailbox and no dupes there.

Come on Apple, I have 100 users at my office waiting for this to be fixed. for now we are still using entourage since the Mail app has not been proven to be reliable.

Thanks masterkain for verifying my observation that SeenMessagesManager is throwing an exception.

This points to a flaw in Mail.app.

Apple, make an exception and fix this flaw!

I'm not sure you all know this but Apple doesn't monitor this forum. This is a user only forum. In order to get Apple to respond to issues such as this, you'll need to contact Apple Care and open a trouble ticket. Only when enough people complain about this problem will Apple dedicate the resources necessary to fix the issue. Unfortunately, this forum is not the best avenue to get Apple's attention.

Great, here we go again.

Just noticed that once again my junk and deleted mail was being stored on my Mac as Mail couldn't store it on my MobileMe account for some reason. So I shut down Mail and opened it up again, and it's now in the process of downloading 18,417 duplicate messages.

I've mentioned it before, but for the record I only have Mail checking my MobileMe account, and this time I've not been using my MacBook, just my Pro (and iPhone)

Just to add to my previous post, this is an IMAP account so the MessageUidsAlreadyDownloaded3 trick isn't going to work here, and it also suggests that isn't the root of the problem.

With it being an IMAP account, I can't delete the duplicate message or it will delete the original as well. I had this problem for the first time a couple of weeks ago, and found a solution that instantly made the duplicates vanish from Mail and stopped it downloading duplicates (until now). Trouble is I thought I found it in this thread but can't find it anymore, I wanted to use it again to get rid of the duplicates and then just try running Mail in 32-bit mode until this gets fixed.

[EDIT:] Just found the solution I was hunting for (to delete IMAP duplicates, not prevent them happening) - in Mail Preferences, go to the Account/Advanced tab, disable the account and save (all messages will disappear), then enable it and save (original messages all come back)

Well I'm not so sure about that. From my experience on at least one occasion, a post of mine that expressed frustration with Apple's lack of response (no expletives etc, just polite frustration) "mysteriously" vaporised within half an hour.

I just called Apple support to complain about this problem. I'd been holding off until now, figuring I wouldn't bother them with a problem I knew they didn't have a solution for, but I decided it was worth adding some fuel to the fire by complaining. The support rep wanted to be helpful, but he was reading this very thread and suggesting some of the things I've already tried (like deleting the "UIDsAlreadyDownloaded" files from the library folder, etc.)

He then suggested that I delete and recreate the problematic Mail accounts, promising that my mail messages wouldn't be deleted by doing so. But when you go to delete a mail account, you get a very specific warning that you will lose all the mail messages from that account. So I'm not really willing to take that step as it seems like it would cause me to lose thousands of messages. Has anyone tried it with any success?

I was hoping they'd be able to assure me that Apple had engineers focused on fixing this problem, but I didn't really come away with much assurance. Support was definitely aware of the problem, and the gentleman I talked to said it was undoubtedly being looked at, but he wasn't able to give me any definitive information that a fix was on the way.

I should have been more clear when I said Apple doesn't monitor this forum. What I meant to say is they don't acknowledge these discussions as a communication mechanism to report problems.

In fact, they do technically have folks that monitor this forum per the "Discussion Terms of Use". But, they make it abundantly clear in the terms of use that they are under no obligation to provide a response.

As per the Discussion Terms of Use:

Once again, another e-mail dump. I m now getting a duplicate dump at least once a day now, when the problem had previously gone away for over a week at a time. Absolutely nothing has changed with my settings in the interim.

My duplicate email problem started after I bought and connected Time Capsule and started using Time Machine to back up my files. Since then, every so often (apparently randomly) I get emails that I've already read and/or deleted, sometimes just one duplicate, sometimes more. Think Time Capsule/Machine has anything to do with it? I'm running Snow Leopard.

By the way, the header to this thread says that the original question has been answered (green star). How do I find this answer? Where's the green star answer?

My problem started after I got Time Capsule and started backing up with Time Machine. Any fix that you know of?

Don't be fooled. This question is not answered. The only thing question that this thread has answered is "Is there any known limit to Apple's arrogance?" The answer is "no."

I have also double messages that started with upgrading Mail. Worse, very old mails (4 years old) are also double but when I click on both of them they are EMPTY.

I run .me account (former .mac) and all my email is on the mac IMAP server, so that's not really a provider problem but more like an apple problem.

I love mail but I hate this, I have backups but have no idea how I can merge them with my newer data.

I believe this is a snow leopard bug. My mail was clean until I upgraded and I've been on POP with two accounts for years. I think we will have to wait until Apple is ready to fix this issue. I've just set my accounts to get mail manually.
