For Mail Basic & Mail Business email accounts

Learn how to set up your email account in Mozilla Thunderbird.

For Microsoft Exchange 2013 email accounts, please reference Setting Up Microsoft Exchange 2013 via Outlook Configurator.

For Office 365 email accounts, please reference Installing Microsoft Outlook and Setting Up an Office 365 Email Account.

Mail Business accounts can be set up in Thunderbird for email use only. To access your address book, calendar, tasks and drives , please log in to 1&1 IONOS Webmail.

Step 1

Start Thunderbird and open the setup wizard via File > New > Existing Email Account.

Step 2

Enter your name, email address and email password now.

Hint: If you do not want your password to be saved, uncheck Save Password.

Step 3

Confirm your entries with Continue.

Thunderbird now automatically searches for the email servers in the Mozilla ISP database and enters the 1&1 IONOS servers.

Step 4

You can now choose whether you want to retrieve your emails via IMAP or POP.

Hint:We recommend that you use IMAP, as the emails remain on the 1&1 IONOSserver and can be retrieved, for example, on the go with your notebook or smartphone.
