The user accounts of students registered as non-attending are not valid during their period of absence. You can reactivate your account once your attendance registration has been recorded in Sisu and the term you registered attending for is ongoing.
The user accounts of students registered as non-attending for the summer months will be reactivated automatically to ensure that registration for the academic year in the Oili service will also be successful during the period of absence. When you register as attending for the autumn term, the validity of your user account will automatically continue after the summer months.
If you have previously had a University of Helsinki user account, it can be restored if, for example, you pursue open university education after graduation. Accounts can be restored if less than a year has passed since their expiration.
Files and emails associated with user accounts are preserved for one year after the username expires.
Visit the IT Helpdesk website for further information on the expiration of user accounts.
