Thunderbird instructions

Here you will find instructions on how to set up your e-mail account in Thunderbird (IMAP).

Mozilla Thunderbird is a free e-mail application that now includes the Lightning add-on for appoitnment and calendar managment as a default.

For working smoothly with Tunderbird, it is important to regularly update the software and add-ons. Non-updated clients often lead to erroneous behaviour.

Install and Setup of Thunderbird

1. For example, download the latest software from https://www.mozilla.ord/de/thunderbird/

2. Start the set-up assistant and follow the instructions

Set Up 1

Set Up 2

Set Up 3

Set Up 4

3. After starting Thunderbird you decide for which areas Thunderbird should be used as a default application program or skip this integration.

4. To set up the university e-mail address, select the button "Skip this and use my existing email".

Set Up 5

5. Enter your name and your e-mail address here and klick on the button "Continue".

Set Up 6

6. Thunderbird searches a database for the correct settings for the server. However, the settings found must be edited using the "Manuel config" button.

Set Up 7

7. Plese be aware that it also works with other ports, but the ports selected here use a secure connection.

Incoming mail server:; Port 993, SSL/TLS; authentification: normal password.

Ougoing mail server:; Port 587; STARTTLS; Authentification: normal password.

Username: Uni-ID makes sense, since some functions (e.g. allocation of rights) only work with the Uni-ID and not with the alias.

Set Up 8

8. After klicking on the "Re-test" button so that the changes can be applied, the setup of the e-mail account can be finished by klicking the "Done" button.
