Office 365 Rest api auth

Question

I'm trying to use the Office 365 api to fetch user's calendar events. I managed to get a valid oauth2 access_token, but when I use the api, the authentication fails.

GET https://outlook.office365.com/api/v1.0/me/calendars
Headers:
    Authorization: Bearer **MYACCESSTOKEN**

A very slow response (about 5 secs) give me a 401 Unauthorized...I have already checked that my access_token is not expired.

Response headers:

Any idea ?

Thanks for your question. The 30s delay with some requests is a known issue and we are already working on a fix to address this. Sorry for the inconvenience.

Thanks,

Venkat
