Why is our published Outlook calendar showing as 1899 in our website

Our outlook calendar looks fine in outlook but the shared link (html) that we use on our website is showing the calendar as 1899. We have not made any changes to our website so can only assume Microsoft has made some kind of update that has caused this?. How do we rectify or get Microsoft to resolve the issue?

If you click on Today then that takes you to the view that users should be seeing but obviously our users will not know to do that (and why should they)

Just to add to this, if you copy the shared html link from outlook and paste into the browser, the issue is replicated without going via our website so the issue looks likely to be a Microsoft Outlook one?

    I had the same issue this morning. I resolved it by launching the shared calendar link, clicked on "Today" on the calendar, and then copy/pasted the URL link over the existing shared link. Once I launched the updated URL, it lands on today's date.

    Seems to be an internal issue at Microsoft causing the bug though.

    Had reports of similar issues with Outlook shared calendars (hosted in Exchange online) in the last few days defaulting to December 1899 when opened.

    Our calendars are being viewed from digital signage room schedulers, where the HTML version of several calendars is used for reservation purposes. There is no interaction (with intent). Several of our calendars just show January 1, but the date highlighted is December 31st, 1899. I'd insert a photo, but that's not working either, Microsoft.
