I am getting 500 internal server error on https://graph.microsoft.com/v1.0/me/calendars

Question

Since may 30th, I have been getting the 500 internal server error on https://graph.microsoft.com/v1.0/me/calendars.

If I use the graph explorer, it also shows the same error - other APIs are working for calendar. This is the response body:

{
    "error": {
        "code": "ErrorInternalServerError",
        "message": "An internal server error occurred. The operation failed."
    }
}

How can we have someone investigate?

Hi David Narine

Thanks for reaching out on Microsoft Q&A!

Could you please try the following endpoint:

https://graph.microsoft.com/beta/me/calendars

If the beta works, but the v1.0 isn't, it most probably is a fix underway. However, if it also doesn't work please raise a support ticket through the Microsoft 365 Admin Portal.

Of course, for the time being you can use the BETA API as the risk and impact would be quite low on this API, even though not ideal for production environments. As soon as the issue is solved you can switch back to the v1.0 again.

Tas Drake found a workaround. It solved the issue on my case. Weird that Microsoft hasn't even acknowledged the issue.
