The message “email_subject” could not be moved to the mailbox “(null)”
Using macOS 10.14.6, on a MacBook Pro (Retina, 15-inch, Mid 2015), Mail Version 12.4
I highlight an email in my inbox. When I attempt to move the email to junk by clicking on the junk icon in the menu bar at the top, I get the message in the above subject line. So currently junk mail is filling up my inbox.
I quit out of mail and then reboot the MacBook. Bring mail back up. No change.
I click on the junk mailbox on the left-hand column under 'Mailboxes'. Then I click Mailbox > Rebuild.
Nothing seems to happen and the above behavior does not change.
Does anyone have any suggestions as to how I can get rid of all these junk mail items?
Thanks!!
MacBook Pro 15″, 10.14
