FAQ - RWTH-E-Mail

In order to find out your mail address and username please log on to the Selfservice on https://rwth-aachen.de/selfservice/.

Next, select the option "Accounts and passwords" on the left and click on the service "RWTH-E-Mail". If you have more than one mail account at the RWTH, more than one service will be displayed with this name.

Here you will find the username in the form username@rwth-aachen.de (e.g. ab123456@maildomain.rwth-aachen.de). Aside from this username, you will need the password for your "RWTH E-Mail" account in order to log in successfully.

If you click on the pencil next to the service "RWTH-E-Mail" you will get an overview for this account. There you can find your e-mail address under "sending Address".

For data protection reasons, no changes can be made to the content of the account profile by the respective user themselves.

Only the profile picture can be changed or removed, as this can also only be added by the user.
If your account has a profile picture, this is because you have explicitly created a contact for your own e-mail address on your smartphone and assigned a profile picture to this account.

This picture is then also displayed in the RWTH Mail App (OWA) in the menu item Options → General → My account. However, this image cannot be changed via OWA.
If you want to change this picture, please change the profile picture that has been assigned to your contact on the smartphone. You can also delete the picture so that a profile picture is no longer displayed.

In addition to the e-mail functionality, Exchange provides further groupware functionalities, such as calendar functions and the contact book.
Mobile devices are also supported.

The following e-mail clients support the additional Exchange functionalities

• Outlook / Outlook for MAC
• Outlook Web Application (OWA)
• Thunderbird and Lightning with corresponding plugins for calendar synchronization
• Apple Mail

For Linux systems:

• Outlook Web Application (OWA)
• Thunderbird and Lightning with corresponding plugins for calendar synchronization

• Students must first register the name change with the Registrar's Office
• Employees must first report a name change to the responsible HR department (subordinate to department 8.0)

Regarding the export, the format is crucial so that you can import your own calendar in another "calendar" app.
We recommend to use Thunderbird for this purpose. By means of the integrated Lightning (calendar app) you also have access to your calendar and can perform the export.

(Background: On the server side, only an export in Outlook format (PST) is possible, this can only be used in Outlook).

You can sign your e-mails digitally, if you use the RWTH MailApp. To do so, you need to install the corresponding S/MIME Plugin.

In chromium-based browsers, you may first have to allow the installation and set up the corresponding certificate chain on the computer or in the browser so that the user certificate is recognized as trustworthy.
