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 used http://www.weirdkid.com/products/emailchemy/ and exported as MBOX-format - and all is good.
Apple Support was no help at all, sadly. They didn't even wan't to report is as an issue... :-/
It's the politically correct way to say they changed a feature in an app. So technically, it's not a bug.
Same problem here. Surfed the web, no solutions yet.
Now I'm trying to export to an external drive, maybe it a SSD file size restriction... I'll come back with an answer
Nop.... external drive also stops at 2,15 Gb
Yes - having same problem months after you wrote this.
Export Mailbox file size limit
