(Thanks Colin!) I would suggest trying this first before the steps to delete and re-add the Gmail account below.Ĭlick the Apple menu (upper left corner of your screen) > System Preferences > Internet Accounts.Ĭlick on each of your Gmail based accounts and see if you're told to open a browser and confirm your password.

Here's a great suggestion for what worked from a commenter. Update March 30, 2021, How to confirm your Gmail accounts in Apple Mail Even adding the SMTP server manually in Mail didn't help. Her outgoing email account (SMTP server) for a Gmail based email account kept appearing "Offline" right after she set it up.

I originally wrote this post when I helped a friend with her outgoing email in Apple Mail.
