cannot send message using the server Google
How do I remove the error popup: "cannot send message using the server Google"? There is 'outbox' to remove the email I was trying to send. And I cannot get the pop up to move. I shut down the MacBook and rebooted, but when I open mail there it is stuck. I took accounts offline. That didn't do it either. HELP!
MacBook, macOS 11.7
