Multiple Copies of Emails

I installed Snow Leopard yesterday. When I came down this morning I discovered that all of my rogers.com email boxes had 4 copies of each email in each in box. The me.com mailbox did not have this issue. I put them all off-line when it appeared that copy number 5 was starting to download. The box to delete files on the server had ben reinstated for one of the rogers accounts, which had not been set in Leopard. I have used this computer since late May using Leopard without this problem. Any suggestions? I haven't yet called Apple or Rogers.

I am experiencing a similar issue. Two copies of each message addressed to my company Exchange account. After I open and read one copy, the extra one disappears when I attempt to open it. I have not yet found a work around. I am reluctant to trash my mail prefs file because that action requires that I reenter all my account information for six accounts. Deleting the mail caches and rebuilding them did not remedy the problem.

Hi again -- sorry to not get back sooner, but had some family urgencies.

Double-click on your hard drive's Icon to open a Finder window -- click on the Icon of a House in that Finder window to get your User Directory (Home). Once there click on Library, and then find and open the Mail folder within this Library. Are you still unable to find a file named MessageUidsAlreadyDownloaded3?

Since you have POP accounts, this is a major issue, and without that file nothing would prevent Mail from continuing to download all messages on the server!

What was the first version of OSX you were using when you established these accounts? In the Mail folder, please report all the files found at its root level? In the POP account folders, is there any file with MessageUids in it name?

I think you will need to purge the com.apple.mail.plist file, and once again setup your email accounts, but we should not this until we consider everything in the Mail folder itself.

So after a week of flawless e-mail operation, suddenly out of the blue, I find 403 e-mails downloaded from my server today – everything back to September 22, the last date the server was purged of previously downloaded messages (I purge after an e-mail is one week old so it is available online if I need it).

Why would mail work perfectly for over a week then inexplicably fail massively again?

First it was every day, then every few days, now once a week? What is going on here?

Still having this mail duplicates issue. It's driving me nuts. Hoping for an apple mail update everyday, but it doesn't come.

Also want to note that within the last few days, mail's lost it's memory as far as remembering previous email addresses as you type them up in the to: field. It's having to start from scratch to remember them all again.

Any ideas on that? Anyone else having that issue that is having this issue as well?

Similar problem. For me, I am running a MacBook Pro and an iPhone as the only two devices checking for mail. I use an Exchange Acct from work as the only email server. Duplicates are hit or miss (they are there today) and I never have more than two. I never have duplicates of messages that I have checked, only of new messages. The duplicates only show up when I first start up Mail, never with subsequent messages. There are no duplicates on the iPhone. I cannot delete the duplicates from Mail but I can read them. I copy my Mail folder from my user/library folder to the desktop (as a backup), then rebuild the inbox. The duplicates disappear and I can delete anything I want.

I have not seen a solution to this yet, have submitted it to Apple.

I have a Time Capsule. Although, I suspect that most people use Time Machine and not all are experiencing this problem.

I am finding that it happens irregularly. I can go a week or longer without any problems, then suddenly all or one account starts to multiply. My most recent experience was this morning - after about a 10 day period without any email duplicate action.

At this point I think it's totally random; I recently joined a Snow Leopard Server directory and Mail automatically created an account on my machine using IMAP, I was using the same account since years and was POP3 configured. Eventually Mail kept this account, which is one of the two I was seeing duplicates.

I deleted the POP3 account and kept the IMAP one, and no problems of duplication thus far.

I never use the other account on which email sometimes duplicates, so I also think that the problem not only is random, but also not linked to the pop3 server or general email activity.

Anyway I think Apple is investigating, we'll probably see a fix soon; at least that's my hope 🙂
