Note: This article is for reference only. Our GoDaddy Guides can't help you with any issues related to Thunderbird. See our Statement of Support. To get the most out of your email address, we recommend setting up your email with Exchange settings. This may require a different email client, like Outlook or Mail for Mac or Windows.

Add your Microsoft 365 email to Thunderbird for Mac or Windows PC. Then you can send and receive emails from your Thunderbird client. Before continuing, make sure that you're using the latest version of Thunderbird.
