Shared Calendar

Since the Exchange Server 2019 CU14 Mar24SU was installed, shared calendars can no longer be displayed.

I have been able to reproduce this on several systems.

When I call up the OWA link (e.g. https://owa.domain.de/owa/calendar/8d.....042d094f38de37bcdcc123890488592235454269/calendar.html ),

I only get the message “This Calendar isn't avaiable. Please try again!”

No anomalies in the ExchangeHealth script, no entries in the event log, restarting the services was unsuccessful.

Extended Protection is disabled for all virtual directorys.

Before the update installation, all shared calendar links worked. It is also no longer possible to reshare a calendar.

Is anything known?

    There is a new hotifx update, however I dont know if it will fix your issue:

    You should also enable extended protection.
