Scheduling and managing events using Outlook.com calendar
Hello ErikDoe,
Let me help you further with your concern. I understand that you have tried re-adding the calendar but it seems that this does not make any difference. You also noticed that it will take some time to have the subscribed calendar refresh on Outlook.com.
Please be informed that Outlook.com Calendar is not responsible for the updates on a third party subscribed calendar. What I can suggest is you contact the calendar publisher and inform this to them.
Let us know if you need further assistance.
Thank you.
