The too many simultaneous connections is from gmail, not Mail. Google limits the number of simultaneous connections to their server to prevent someone from hacking into your gmail account. It mostly prevents me from reading my email.
When Mail opens a connection to an IMAP account, it generates multiple connects to allow real-time, upload, download, sync, etc. instead of one connection that must wait for the others to finish. Depending on the positions of the Moon, Sun, and Uranus, Google will identify this as too many connections.
I can usually unlock it by logging into the gmail web interface. I'm not sure why adding the connection clears up the other connections, but there you go.
I started having this problem today with two accounts (one with gmail, one with google domains). I tried your suggestion of logging into gmail and that didn't help. I tried several times with both accounts but made no progress. Then I quit Apple Mail, logged in to Gmail, logged out of Gmail, logged into my google domain account, logged out and then launched Apple Mail again. Problem solved! I can access both accounts without a problem. I also access these accounts from my iPhone and that never failed to work during this entire episode.
In case anyone else runs into this problem, give this a try.
