Managing the profile

Use the following forms for managing profiles:

The University of Vienna offers 6 possible profiles. Every profile has different permissions and functions.

Premium profiles are assigned to individual persons. Requirements to the assignment of a premium profile:

  • Employment with an active working address at the University of Vienna; Human Resources Administration is responsible for entering and deleting your work address.
  • Active e-mail address at the University of Vienna

Extra profiles are assigned to persons outside the University or persons without an active University of Vienna e-mail address. In addition, they are used for non-personal phones (e.g. in lecture halls or laboratories).

30 days after termination of your employment, your profile including the call journal and all contacts will be deleted automatically.


Save your profile data before they are deleted, as it is not possible to recover them afterwards.
