3. Examine the Connectivity of Gmail TCP Ports

When Outlook cannot connect to Gmail, you should see whether your device or Internet Service Provider isn’t blocking the network ports employed to access Gmail. To inspect ports on Windows 20, utilize the ‘Test-NetConnection PowerShell‘ CMDLET. Examine the availability of Gmail servers on these protocols: SMTP over TLS (587) and IMAP over SSL (993). Launch the elevated PowerShell. You can use ‘Win + X – Windows PowerShell (Admin)‘ and execute the commands below.

  • Test-NetConnection -port 993
  • Test-NetConnection -port 587


In case you are utilizing another Gmail server in Outlook, inspect the connection through the commands below. 

  • Test-NetConnection -port 993
  • Test-NetConnection -port 587


In case the command gives ‘Tcp TestSucceeded = False,’ it implies that access to your Gmail account is obstructed by a Firewall. Inspect the third-party firewall settings or Windows Defender Firewall on your device. Permit the outlook.exe process to dispatch the outgoing traffic over the TCP 587 and 993 ports.

5. Permit Less Secure Applications for Gmail

If you are unable to connect Gmail in Outlook, you must pay attention to the security settings. You can permit less secure applications for Gmail. Follow these steps for it.

  • Open your Gmail account and click the profile picture. It will allow you to access ‘Manage your Google Account.’
  • After that, select ‘Sign-in & Security‘ present on the left menu. Follow it by selecting ‘Less secure apps access.’
  • Now search for ‘Allow less secure apps.’ Enable this functionality.
  • Now tap ‘Save Changes.’
