UPDATE: Malfunction signing in to university services

8 May 2026


Update 15:45 h

We have been working hard to address the consequences of the disruption that occurred Thursday evening, which resulted in a large number of staff accounts being set to inactive.

ISSC has announced that the reactivation process of these accounts is going well: a lot of staff members now have access to their accounts again. Those who are still unable to access their accounts are kindly asked to be patient for a little bit longer. We hope to have all accounts reactivated as soon as possible.

Staff who should now have access to their accounts and/or, for example, Teams, but are still encountering problems, are advised to restart their own laptop first. Only then will it be possible to regain access to their accounts and other services.  

We understand that this disruption is causing problems for our staff, and we regret that this has happened. Anyone who is still experiencing certain IT issues after activating their account, can contact the ISSC Helpdesk after the weekend. The staff there will be ready to assist you.

A further update will be posted here when there are relevant developments to report.

Update 11:35 h

Dear colleagues,

As you may have noticed, the university is experiencing a disruption. This is the result of an internal technical issue, whereby a large number of staff accounts were set to inactive on Thursday evening. As soon as the issue was identified, the process of reactivating all accounts was initiated. This process is still ongoing, it is currently unclear when all systems will be fully operational again.

In addition to being unable to access your own account, you may also temporarily be unable to use other services, such as Microsoft Office or Salto. It is therefore possible that you have regained access to your UL account, but not to these services. This issue is also temporary in nature.

We regret that some of our staff have been affected, as this may hinder your work. We would like to ask all affected colleagues for a little more patience, and to check periodically whether your account has been reactivated.

An update will be posted here as soon as there are any further developments to report.
