Apple mail accounts & boxes Missing

If I may tag along - Same problem. I have recreated the mail accounts, but now don't have the mail boxes (hundreds, all with content going back years). I do have Time Machine backups if that helps.

Yes have the same problem.

My mailboxes are huge. Be great to have a solution so can get back to work.

If the mail boxes still show up, then look next to them for a + and show and hide button. click on show.

Slame issue for me. Need to get the old messages back as have lots of important info stored.

Found it! Go to the "mailbox" menu and choose "rebuild". Missing mail is back.

I have to say, this is a truly horrible bug.

I think I did it the hard way. Recreated the accounts, which was no bad thing as I took the opportunity to tidy them up.

Then I used Time Machine to bring back all the "On My Mac" items.

It did re-build sub-folders too, so I should probably have one top level folder with the others under it.

Just glad I've been doing Time Machine backups 🙂

Thanks you saved me my nerves this morning! 🙂

That Rebuild suggestion didn't work for me , I tried.

I am missing my "Saved Mail" Folder that I had created, and am missing my "iCloud" Folder too.

Also having the same (but different?) problem. NONE of my x7 mail a/c's (imaps, pops, gmail, iCloud, personal website a/c, yahoo etc) are showing at all and the 'rebuild' option is unavailable as there are no mailboxes! I didn't do a clean install and everything else on my iMac is as it was. ARGH! Never had this issue in 24yrs of using macs. This doesn't mean I'm tech savvy though - can someone please help / anyone have same issue? Many thanks.

The suggestion...Go to the "mailbox" menu and choose "rebuild", did not work for me. Other ideas??

Glad I helped. Pure luck that I found that switch. a sigh of relief.

Hi Trisha Foster. I use classic view in my mail app and all of my mail boxes are in a column on the left, next to iCloud there is a + sign and a hide or show button; click show. Also, right click on an email and select copy to and a menu of available mail boxes will appear even ones that are hidden. If your missing mail boxes show up there, then they are just hidden. If not there, then ask for more help.

Good Luck: Tom

Note that you have to rebuild each individual mailbox. I had to select the "sent" mailbox separately, and then choose "rebuild" to get back my sent messages.

Thanks nokcomputer, you saved several handfuls of my rapidly-thinning hair! 🙂

Quite why the user has to manually trigger the rebuild, I've no idea - surely it could have been done automatically as part of the upgrade?!

To those who say this didn't work for them, it could be a case of having to wait a while - mine took about 5 min, maybe more, of apparently nothing happening, and then all of a sudden it all just appeared. (To be fair, I have thousands of messages in my inbox, so no wonder!)
