Currently, public calendars can no longer be made available via the browser-based Outlook Web App (webmail).
Specifically, this means:
- Calendars that have already been published can no longer be accessed via their previous links. Instead, the error message “500 Internal Server Error” is displayed.
- New HTML and ICS links for calendar publishing are not currently being generated.
This is due to a major security update for Microsoft Exchange that has been deployed. We have already provided information about additional restrictions on the use of OWA in connection with this update.
Microsoft is aware of the issue but has not yet released an update to resolve it.
Good to know: The public calendars are used, for example, in the S(kim) system at the meeting rooms in the libraries. There, a calendar webpage can be accessed via a QR code to quickly get an overview of availability. We hope to be able to make this service available again soon.
