Can receive but not send email
Ever since the most recent update of my MacBook Air 11 to macOS Monterey, one of my gmail accounts will not allow me to send emails. I can receive them all day long, but when I try to send I get the error message to re-enter my password. Then it rejects the password. This happens to be my business email account. My other personal gmail account and my personal (old) aol account work just fine. The email password works on my iPhone and other devices.
Before deleting the mailbox and re-adding it I was hoping there could be a simpler answer?
Thanks for any advice!
