Here is a short tutorial on setting up Scribe v2.3.8 and later to send and receive mail from the Gmail. Note that you need to set both sending and receiving use the OAUTH2 authentication type.

Configure an account in Scribe to access Gmail:

• From Scribe's main window click File → Options.
• Click the Accounts tab.
• Select the account to be used for Gmail, and click Properties
• In the Identity tab call the account "Gmail" if you want. Add a display name and your gmail address as the email.
• On the Send tab set the fields:
  
• On the Receive tab set the fields:
  
  
• Save your changes with Ok.

Then test the account:

• Open out the Status panel in Scribe
• Click the gmail account, and then the receive log tab.
• Watch the progress and Log window to see if it connects and scans the mailbox.
• If it complains that OpenSSL is not installed on windows that get the latest build from here.
