New 'pop up' in Mail
Roy Rainford
When I delete a message in Mail (v 9.3) this 'pop up' appears: "An error occurred while moving messages to mailbox “(null)”.
This is a new one to me but fortunately, Mail continues to operate without a problem. (On iMac with OS X El Capitan v 10.11.6). Should I just ignore the pop up and hope it goes away?
