Mailbox pane missing On My Mac!

Read the article, seemed like it should work to rebuild the mailboxes. Unfortunately, when it rebuilt I lost all connections to all of my emails, gmail, verizon and work. I did keep the files on my desktop so I was able to replace them and get my connections back. You'd think Apple would make this easier especially since the On My Mac shows up as a place to put email!

Thanks for your reply but still not a solution.

That's where I expected it to be but if you look at my jpg above, you'll see the only thing there is "Today".

That's why I trying to put it there again. I know it's in my folder because I can copy email to folders inside it, but I can't get to the folders.

Thanks Old Toad.

Update: I have found it in my smart Mailboxes near the bottom of the other smart mailboxes. If there was a solution I would have to say that the referenced article

"See this article: https://grayjetmedia.com/2016/04/01/recovering-lost-on-my-mac-local-mailboxes-af ter-os-x-10-11-el-capitan-upgrade/"

Did work after all since it wasn't there before I followed the procedure. I'm going to say that fixed my problem.

Thanks all for the help!

Sure, here is the mailbox pane and you'll note On My Mac is not listed.

I know it's there because I can select a message and copy it to a folder within it.

thanks, ~ Mark
