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 contacted MS support yesterday and was told engineers are aware of the issue and working on global fix. Not an issue that can be troubleshooted on local PCs. They asked me to do a developer log run on the published calendar and was uploaded for engineer's review.

    Opening a ticket with MS, refreshing each visit isn't plausible for end users.

    The support at Microsoft is so ridiculous. For those who can read French, this is a response that have been provided. For me, it didn't make any sense... But if someone has any explanation ...

    Cher Monsieur, 

    J'espère que vous allez bien.

    Hier, j'ai escaladé votre demande au plus haut niveau et voici leur retour: 

    Le calendrier sur Outlook en ligne affiche l'année 1899, Cela se produit parce qu'il doit y avoir une colonne de temps dans l'une des tables. Les alternatives sont : 

    1. Supprimer la colonne de temps.
    2. Créer la table Calendrier avec Power Query (ce que je recommande).
    3. Changer le type de données en TEXTE, et cela fonctionne aussi.

    Une des causes de ce problème est que le système interprète la colonne de temps comme Date Time pour une raison quelconque. Peut-être essayez de convertir cette colonne en décimal juste pour voir si c'est bien ce qui ne va pas (changer la colonne de temps en décimal). 

    Enfin, une dernière solution est de lancer le lien du calendrier partagé, de cliquer sur "Aujourd'hui" dans le calendrier, puis de copier/coller le lien URL sur le lien partagé existant. Une fois que vous lancez l'URL mise à jour, il atterrit sur la date d'aujourd'hui. 

    Veuillez essayer ces étapes et tenez-moi au courant des résultats. 

    Cordialement,

    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.
