Missing emails in Mail - Lion deleting them?

I haven't been keeping up with this thread but, to me, one critical downside to the Apple Mail under Lion (OS X) is that threads "disappear" inside the original note. It's driven me crazy, as well as caused problem when I didn't see a note that was sent as part of a thread that had drifted back in the queue. Aggravating!

That can be retified by using Classic View, although the view in Lion is very much like that on any iOS device.

FIXED! FIXED! FIXED! FIXED! FIXED!

Wow, I've been suffering with this forever - turns out my iPhone AOL mail was set to POP, and my OS X AOL mail on my Macbook Pro was set to IMAP. Changed my Macbook to POP and all is right in the world! All email received, no more disappearing emails! Thank you Ernie!

I'm losing emails too. Have been able to replicate the problem with one sender, who is using Yahoo mail on a pop server. Everything I get from him disappears. I'm wondering if most of the emails here were coming from Yahoo senders....

I'm also noticing that the Yahoo mail user whose emails are getting deleted has been emailing me at my old me.com address, when the address that I use is a mac.com address. Normally the me.com address works, but I'd like to get ride of every vestige of mobile me that has ever existed on any of my computers! I don't know why Apple is hanging on to the me.com address, I can't seem to delete it.

Mac.com and Me.com are the same, Me is the newer of the 2 but both are functional iCloud addresses, just as they were both functional Mobile Me addresses.

Yahoo accounts can now default to being set up as IMAP. If one or more devices or computers happen to set the same account up as POP, then things can happen to remove the message from the Yahoo servers, and then in an account setup as IMAP they will be lost.

Carefully confimr all devices are consistently using the account as either IMAP or POP, but not mixed.

Thanks Ernie. I've solved it for the moment by deleting my mail account and re-installing it. Immediately my mail started coming in and I haven't lost any since.

Mine started going wonky after I upgraded to Mountain Lion.

same issue here, on multiple computers and OS versions:

brand-new Imac with Lion and another imac with snow leopard both recently noticed emails missing. Emails were received on both computers, read, not deleted, and returned later to not find certain important emails on either.

lot of similiar responses on this topic, and I have a LOT of reading to do to see if anyone's solutions may apply to myself. Pretty sure I will simply migrate my entire office away from Mac Mail entirely unless I can resolve this issue asap. We have to reference emails from months, even years, back to keep work flowing through our shop and if we're noticing emails missing now.... who's to say we haven't lost even more emails (and business) along the way?!?

also noted, I'm also experiencing difficulty with my own mail... to which I have setup on my iphone, mac-mini, mac pro, and macbook pro. Until recently, i believed that everything has been fine and I could access my inbox from either platform.... but now I'm noticing that each platform is receiving a few emails from the whole, daily. I don't know if this contributes to the issues in this thread, but up until a few months ago... everything was working perfectly (i think, but now I'm so baffled that I will have to do a LOT of digging to confirm the extent of my issues.)

Just figured out that imporant emails have gone missing from my Mail iCloud account on my computer.

Very unreliable.

I have been searching my inbox to no avail. Glad I usually use Gmail for important stuff.

Thanks for sharing 😐

You seem to go around trolling all of my replies...

I have been having problems as well. I have 7 email accounts all with the same ISP. Two are not having any issues and they are both POP accounts. The others are all IMAP and the messages in my inbox are disappearing after about a week or two. I do not see any preference settings on having them automatically delete.

My Sent box- they are all there as well as my trash box - they are all there.

So it is just the important email that I am saving in my Inbox that has disappeared and they are all IMAP. Any solutions yet??

Have any of you found a solution. This just happend this week to me. I read to up grade to OS X Mountain Lion, I'm downloading now but what about all the lost emails I have to get to for work?? I wish I would have left them on the server, but its my 600 sent emails I really need access to. I guess going forward I'll save those on the server too. I REALLY need to find a way to get them back!

HELP!

I had this problem and the instructions at this link fixed it for me:
