User case: Gmail stopped syncing to Outlook 365 for Mac
“Using the original version of Outlook as the new mail is not complete until it supports local folders and apple script. And it's worthless to me without those features.
As of today, both of my gmails stopped syncing. When I try to sync, it wants to sign into Google. So I sign in, but then it doesn't do anything afterward I'm signed in on my browser. Usually at this point, it recognizes the sign in and proceeds to sync up. Not anymore.
It's signed in but waiting for me to sign in, have tried signing in several times, with 3 different browsers. All the same results.”

Why Outlook for Mac not syncing with Gmail?
When Gmail stopped syncing with Outlook for Mac, several factors could be causing the issue. Here are some common reasons:
- Internet Connectivity Issues: A stable internet connection is required for email synchronization. Any interruptions or weak connections can prevent Outlook from syncing with Gmail.
- Firewall or Antivirus Interference: Firewall or antivirus software on your Mac might be blocking Outlook's access to Gmail servers.
- IMAP Not Enabled: Gmail requires IMAP (Internet Message Access Protocol) to be enabled for third-party email clients like Outlook to access and sync emails.
- Permission Issues: Outlook might not have the necessary permissions to access your Gmail account. This can happen if permissions were revoked or not granted correctly.
- Outdated Software: If either Outlook or macOS is outdated, compatibility issues may arise, preventing proper syncing.
