问题
Our setup is an on-premise Exchange Server which is accessible over the graph api. https://docs.microsoft.com/en-us/graph/hybrid-rest-support
We run in the issue, that our token is only "partial" working. And a token created by "Graph-Playground" is fully working. But we can't find any difference.
- When I use Graph-Playground or use the token generated by Graph-Playground => all requests are working
- When I create a token (over my app registration) => only some requests are working
The token seems to be valid some calls like /me are working, but all calls related to exchange like /me/contacts are failing with this error
Request, they work with token generated by Postman:**
Error:
{ "error": { "code": "MailboxNotEnabledForRESTAPI", "message": "REST API is not yet supported for this mailbox." } }
(that's a very generic error, and mostly don't say anything about the real issue)
Token Generation:
I create my token on the same way as Graph-Playground create the token (OAuth - Implicit flow):
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=token&state=test2&client_id=????&scope=openid%20profile%20User.Read%20email%20Contacts.Read&redirect_uri=????
Token - Analysis:
As a side note, it was working for a few days, nobody changed anything :)
So I have no idea, why the "Graph Playground" can create a working token, and my token only "partially" works. Can you help me?
There is already a thread, but I'm not the owner of it. Also there are no more responses... I can't provide a bounty for a foreign thread, that's why I create a new thread. You can find it here:
