This is new to me: with High Sierra I am not able to export .mbox file larger than 2.15Gb. My Inbox is 2.9Gb, when I export it, the .mbox file size is always 2.15Gb!!! And if I import this 2.15Gb file, hundreds e-mails are missing from my original Inbox.
I also tried to export the .mbox to FAT32 or ExFat or any other format... same result.
This used to be an easy task... now... High Sierra!
Anybody knows how to fix this?
I have a inbox that is larger than that.
However ,I am dealing with a different bug. The exported .mbox doesn't include any attachments that are attached to my email. So the result is a big mailbox down to a small one with lots of information (in the form of attachments, missing). I haven't even cross referenced it yet to see if it includes all the messages.
I brought it up over on this thread on the Community forum.
Attachments missing from Mailbox Export - mbox file
I contacted support and they definitely think my issue is a bug so I'm waiting for a call from Engineer support to get them more practical details.
Hmmm, this is new to me. I don't have a folder large enough to test so can't verify one way or another. Microsoft Outlook uses this limited file size, but Mail has always been unlimited before.
There is an alternative third party product EmailChemy that can export your data as a real .mbox not an Apple .mbox that is unlimited. You can try the demo first. The demo puts a watermark on the messages. If you like it, you will have to run again after purchasing so there is no watermark.
Emailchemy $29.95
I work on client's computers all the time, but no one has updated to High Sierra so I could test. While I have High Sierra my entire Mail data is not 2GB much less a single folder.
I started a post here to see if anyone has an answer....
Is Mail export in High Sierra limited to 2GB | MacRumors Forums
I'm having the same problem, and it always stops at 2.15 GB. I've also tried deleting the first set of 2.15 GB that I was able to export, and then exporting the next 2.15 GB of emails, and when I imported the second file back into Mail, the file contained half of the deleted and half of the new emails!
Same Problem! 2,15 GB then it is finished! One observation: The Storage used by MAIL is increasing up 10GB (that is about 3 times the size of the mailbox).

Many years no problem, now I even cannot export mailboxes anymore, really annoying!

Apple seems to forget the basic functionalities in its software! No experts, no support seem to care about all this! It's about downgrading and lack of testing!
Hope within the next months or years somebody from apple discovers and cares about this bug. There seem to be alos a lot of other bugs around the mail-program.
I am not aware of any limit, it would not make any sense.
In my case it is a problem around the storage-management which blocks at the end the Mail-Program.

Emailchemy exports the majority of items correctly. I did run into an issue when an email attaches several email files that have a subject line with a colon ( like Re: or Fwd: ). The attachment names were exported, but not the actual source attachment. I haven't found a workaround yet.
Anyone can test this out to see if it is a common issue/limit or it is just me.
Anyone? Please can someone check if you have this issue too? Thanks.
I'm having the same issue. 2.15GB is the limit - come on Apple, whats going on here..?
Microsoft has the same limit on exporting folders as .mbox files. Emailchemy can export as standard .mbox and does not have a limit.

Any answer about this?. I am having also all exports stuck when exporting 2.1 or 2.2 Gb. Mailbox is several times bigger.
It's not a bug but a change to a feature in Mail. Microsoft has always had this limit.
What feature is that?
That helped me solve the problem - thanks! :-)
But sad, that we have to buy third-party software, to help overcome problems with Apples software.
