Please open your Mozilla Thunderbird. Then press the key combination "Alt + D". This will take you to the file menu. Here you can add a new e-mail account in Mozilla Thunderbird via "New → Existing e-mail account...".

Please enter your name and your HTW e-mail address in the window that opens up. Please leave the "Password field" empty and click on "Edit manually". Then continue with step 2 of this manual.

Please make sure that the following information is entered:

Line 1:
Incoming mail server (IMAP): mail.htw-berlin.de
port: 993
SSL: SSL/TLS
Authentication: Password, normal

Line 2:
Outgoing mail server (SMTP): mail.htw-berlin.de
port: 465
SSL: SSL/TLS
Authentication: Password, normal

For both user name fields, enter only your HTW account user name (e.g. s0000001 or amuster; but not your email alias firstname.lastname).

If all settings are correct, you can finish the process by clicking the "Done" button.

After finishing the configuration you will be asked to enter your HTW password. Afterwards you can use your mailbox.
