Well, if you have a @gmail.com account, that is.
But don’t worry! If you have a Google App account, it can be made to work with little extra work. Here is how:
1. You need a standard @gmail.com account. Create a bogus one if necessary.
2. You will not want to do anything with this account. Not really. Thus, in Thunderbird, go offline: File > Offline > Work Offline.
3. Select File > New > Mail Account…
4. Enter the information for your @gmail.com account. Thunderbird will recognize the address and automatically fill out the following box with the correct GMail information: imap.googlemail.com , etc. Green dots all around! Just click [Create Account]
5. Now, in the left-hand tree, right-click on your account name and select ‘ Settings… ‘
6. Change your account name to something meaningful, then click [OK] -- If you do not do this and exit the dialog, the other screens will not be updated correctly.
7. Re-open the dialog, select ‘ Server Settings ‘ and enter your Google App email account where your @gmail.com account is currently displayed.
8. Select ‘ Outgoing Server (SMTP) ‘, then ’ Google Mail - smtp.googlemail.com ‘ and click [Set Default]
9. Click [OK] , leave offline mode, restart Thunderbird to be on the safe side.
10. All set! Thunderbird will start synchronizing with your Google App account using these optimum settings.
