Using Outlook/Thunderbird with Google Apps
Thee best email service anywhere. I can’t imagine my life without Gmail anymore. It is awesome in so many ways and has so many hidden features and functionality that I can’t believe it’s free.
Recommended settings and configuration for IMAP
If you want Thunderbird to check all of your folders for new messages try adding user_pref(“mail.check_all_imap_folders_for_new”, true); to your user.js or pref.js
