Outlook not synching with web calendar

I want to (re-)subscribe to a web calendar from icloud.com that stopped synching.
iCloud provides a URL (beginning with webcal://p101-caldav.icloud.com/published/2/...)

that I can enter on the Outlook web client on outlook.office.com (Add calendar > Subscribe from internet > enter URL).
Unfortunately Outlook is not fully synching the calendar any more.

To identify the culprit I used the same link on Google calendar and it could sync without a problem.
So the problem seems to be on the O365 side.

Are there any solutions to this problem?

    I'm also looking for a similar solution. I have NOT been able to get the "subscribe from web" calendars that I have subscribed to (using webcals URI) to refresh. I've been searching all over the interwebs for this, and the best I've found so far is: Microsoft's implementation for web calendars is broken and that there seems to be no internal resources dedicated to working on this.

    • That is the "broken" part is correct (I don't know about the internal resources) - external calendar sync has not worked well for a couple of years.  Only fix right now is remove and readd the calendar. :(

        Oh yikes! I'm trying to sell automatically updated holiday calendars to our user population (some 20,000 users across 150+ locations). I should dial down my expectations - and probably NOT launch our Official Holidays with the expectation that additions and updates will automatically be reflected in their calendars :(

        However, in a test I'm currently running, I successfully updated an item (via webcals URI to an ICS file stored in an external file repository - Azure Blob storage, since Outlook cannot negotiate SharePoint document libraries, even if the host site has anonymous access enabled).

        Diane_Poremsky_MVP: do you have other resources on this? I'm really hoping that someone from MSFT (maybe someone on the Outlook product team?) is watching this - and will raise it up in their product backlog.
