Mail: can't remove a mailbox from favorites bar
Hi all,
I've added a local (On My Mac) mailbox to my favorites bar in Mail. I want to remove it (from the bar, not delete the mailbox). I click and drag it off the bar, and see the smoke puff and hear the sound -- then it immediately reappears on the bar!
I can't find anything via Google, so I'm hoping someone can help?
Thank you!!
