Email Folders gone after Mavericks update. -2

@eddie Ski, i migrated from 10.9

I, too, have been strugging with this issue for quite a while. Things that did not work include:

– Rebuilding the mailbox (that just made everything disappear the first time, then had no effect on

successive tries)

– Reindexing my entire mac in Spotlight

– Re-importing the mailbox by dragging it to the desktop, then using import. (Nothing was imported.)

On the other hand, I could see that all of the messages were still happily stored deep inside the mailboxes

I finally realized that the two screwed up mailboxes had the following structure:

~/Library/Mail/V2/Mailboxes/SomeName.mbox/AnotherName.mbox/0748658C-0D7A-40F8-82BC-DCD1AF362130/Data-LotsOfRandomCharacters/blah,blah,blah

whereas all of the working mailboxes had the structure:

~/Library/Mail/V2/Mailboxes/SomeName.mbox/AnotherName.mbox/0748658C-0D7A-40F8-82BC-DCD1AF362130/Data/blah,blah,blah

In other words, somehow the Data folder had been renamed to include lots of randam characters. I copied the offending mailbox (here AnotherName.mbox), renamed the enclosed Data folder to "Data", and imported the folder. All of the missing messages showed up under the new Import folder.

Just to add that I face the same issue.

Mail is running out of memory size and will not work any more.

No possibility to find the folder Mail as indicated above

I CAN NOT GET ANY MAIL FOR 2 WEEKS ... NEED HELP

Same problem -- large Mail folder suddenly had very few messages in it. It might have happend in December. This is an "On My Mac" folder, not an IMAP or GMail folder. When I looked in my mail directory (in my home directory's Library directory: ~/Library/Mail/V2/Mailboxes where the ~ is my home directory), I saw the same kind of thing you did: under the file folder that's the mailbox folder in question I had a directory/folder named "B8E94824-8756-47BD-9280-F497C26EF511" (no kidding) and inside that there were TWO "Data" directories: one just called "Data" and the other called "Data-T0x60800007e180-EtcNtV". The one called Data had the messages I still could see; the other had the messages I'd lost. So I made a copy of the mailbox folder on my desktop by dragging with the option key down, deleted from the copy the Data folder, renamed the copy's Data-T0x60800007e180-EtcNtV to be just Data and relaunched Mail and imported that mailbox folder. Sure enough, all my lost messages were quickly imported. I could then simply drag them into the mailbox folder where they were missing in Mail.

I'm *pretty* sure I didn't lose any messages but I can't be positive.

I checked for other similar file folder Data-... names and found none. Hopefully this is a one-time anomaly.

What in the world caused Mail to rename the Data folder it was using and start using a new one????

I found my old mailboxes in the library by going to MAC HD, Library, Mail,.... but interestingly, When I try to import mailboxes from the V2 folder in the library to my Mail app, the menu does not show "Mail" as an option for importable files. Frustrating... and I am seeing that I am not the only person to lose files. Right now I do not have access to about 8 years of archived email because of this. Pulling it from a time maching back up is suboptimal, because my last time maching back up was about 2 weeks ago..(I know, always back up)

Any thoughts appreciated.

I just "upgraded" my Snow Leopard 10.6.8 Macbook Pro to Mavericks 10.9.2, and Mail is messed up even worse than this thread suggests.

I have my own domain and I've used the Mac Mail.app program to access email (using IMAP) via that domain since 2005 on all the versions of OS X since Panther, except for Lion and Mountain Lion, which I skipped. In my inbox I have 77 messages, most of which are Mail.app "notes" that I've created over the years to keep track of various bits of information. In the Mavericks Mail program, only 16 of those messages appear. In the mail directory on the filesystem on my domain host's computer, those 16 messages are in a top-level inbox directory/folder. The other 61 messages are in a .Notes subdirectory/folder. The Mail program in Snow Leopard on my iMac somehow knows how to aggregate the messages in those two physical directories on the mail server into the inbox in Mail so that all 77 of them are listed in the inbox. In the ~/Library/Mail folder in Mavericks on my Macbook Pro, 16 messages are in the top-level Inbox.mbox folder. The remaining 61 messages are scattered throughout a deeply-nested directory structure in a Notes.mbox subdirectory/folder in the Inbox.mbox folder. Those deeply-nested directories each have anywhere from one to six or seven messages of the 61 missing messages. Mavericks Mail can't "see" any of them.

That's bad enough, but it gets even worse. In the Mavericks Mail program, none of the 16 messages (notes) in the inbox are editable, like they are in the Snow Leopard Mail program. This is a show-stopper as some of those messages are "notes" that I need to update on a regular basis.

As someone who made his living for 30 years writing software on various flavors of Unix and Linux, it is hard to imagine how Mail.app in Mavericks could have gotten so screwed up.

Have you opened the new Notes application? That's where my "notes" from Mail ended up.

Also, I think if you move the uneditable messages to the Drafts folder you can edit them. Or use Notes.

I agree that the migration path for serious users was abysmal.
