Hi @Urban Lundberg

Welcome to our forum!

It sounds like you're having trouble setting up your Gmail account in the new Outlook due to an OAuth 2.0 authentication issue. The "Missing required parameter: redirect_uri" error indicates that the redirect URI is not correctly configured. Here are some steps to help you resolve this:

1. Check Redirect URI Configuration: This is usually configured by the application developer. If you have access to the Google API Console, ensure that the redirect URI matches exactly with what is expected by Google.
2. Enable IMAP in Gmail:
   • Go to Gmail and log in.
   • Click on the gear icon and select See all settings.
   • Go to the Forwarding and POP/IMAP tab.
   • Ensure IMAP Access is enabled and click Save Changes.
3. Check Outlook Settings: It is suggested to move and re-add your account. Verify that the incoming and outgoing server settings are correct:
   • Incoming mail server: imap.gmail.com
   • Outgoing mail server: smtp.gmail.com
   • Ensure that the ports and encryption methods are set correctly (IMAP: 993 with SSL, SMTP: 465 or 587 with SSL/TLS).
