1. Log into your **Webmail**.
2. Click on your **Profile Picture/Icon** in the top corner.
3. Select **My Account**.

4. Your address book will now synchronize with Thunderbird.

#### Troubleshooting Tips

**Verify Your Plan**: Basic mailboxes support email synchronization only. If you cannot see the Synchronization tab in webmail, you may need to upgrade to an Enhanced plan.

**Check Your URL**: Ensure there are no extra spaces at the beginning or end of the URL when pasting it into Thunderbird.

**Direct Sync**: Unlike standard IMAP which only syncs email, these steps ensure your Calendar, Contacts, and Tasks stay updated across your computer, phone, and tablet.
