I need to add a Sharepoint Calendard in OWA. I clicked on "add a calendar from the internet". I am able to enter the URL to my calendar, but not events are showing. Any idea?
From this article: Import or subscribe to a calendar in Outlook on the web, SharePoint calendar seems to be not supported in Outlook on the web.
In Outlook on the web, you can import events from an .ics file to your existing calendar or subscribe to a calendar online and receive automatic updates (known as an ICS subscription or an iCal subscription). You can import calendars from websites or calendar programs that support the .ics file format, such as Apple iCal, Google Calendar, and Mozilla Lightning.
