Hi everyone!

My name is Stefan Colic and i come from Doodle.

We are currently experiencing a number of exceptions coming from the /me/calendars endpoint for the Graph API. We assumed it has something to do with us, but looking at the Graph Explorer, i'm always getting 500 there as well.Screenshot 2025-06-02 at 10.47.12

The issue started on friday and intesified over the weekend. Any input on this?

    Hi @Stefan Colic

    Thanks for posting question on Microsoft Forum,

    We would like to tell you that 500 error usually occurs either due to permissions error or sometimes incorrect graph endpoint.

    We would suggest you to use this graph endpoint https://graph.microsoft.com/v1.0/me/calendar via GET method and if you still want to use calendars endpoint then you need to use https://graph.microsoft.com/v1.0/me/calendars/{id}

    You can go through this documentation for better understanding:
    https://learn.microsoft.com/en-us/graph/api/calendar-get?view=graph-rest-1.0&tabs=http#http-request

    Hope this helps.
