Graph Explorer returns outdated Calendars and not current ones as shown in outlook web

Question

When I query Graph Explorer to get all my calendars (https://graph.microsoft.com/v1.0/me/calendars) I am presented with my calendars plus a series of old calendars that I unsubscribed to many years ago. The response is also missing some current calendars that I AM subscribed to. I am comparing this API response to what I am seeing when I sign into Outlook web.

How do I update or refresh the calendars so that my outlook.com calendars are all shown in a graph explorer query (and no extras)?

Thanks for any assistance that can be provided.

Hi @Brent Warner
Thank you for reaching out to Microsoft!
Please see below and check if this helps!

• Log in to Outlook on the web.

Verify if the calendars are correctly subscribed.

If you see unsubscribed events in Outlook web, that might be why they are appearing in the Graph API response.

Unsubscribe from those events directly in the web interface.

Sign out and back into your Graph Explorer account or re-sync your calendars to refresh the data.

Even after un-subscribing the above, if the issue still persists, I recommend you raise a support case with Microsoft Graph, a Support Engineer will be able to look into this issue and assist you better. You can raise support ticket from New support request - Microsoft Entra admin center or https://admin.microsoft.com/#/support/requests.

Hope this helps.
