Access token response issue.

sonali dudhia 5

I am having trouble with an access_token generated from the Microsoft Entra account API. The access token has admin consent with the scope of Calendars.Read. But when I use it to fetch the URL, I get a response showing code 401 Unauthorized or {"error":{"code":"OrganizationFromTenantGuidNotFound","message": "The tenant for tenant guid 'xxx' does not exist."}. I have verified that the tenant id is correct.

Strangely, I get a proper response when I use the same steps in the Graph Explorer API tool.

Can someone help me resolve this issue ASAP?

Thanks.

Hello @sonali dudhia,

Thank you for posting your query on Microsoft Q&A.

I see that you're trying to generate an access token using OAuth flows for the Calendars.Read API, but you're encountering a 401 Unauthorized error or the message: {"error":{"code":"OrganizationFromTenantGuidNotFound","message": "The tenant for tenant guid 'xxx' does not exist."}

However, you are able to get a response when using the same steps in the Graph Explorer tool.

To help troubleshoot this issue, could you provide details about the URL you're using to send the request? Are you making the request via Postman?

If so, please share a screenshot of your setup in Postman (with any PII hidden). This will help me provide a more targeted action plan to resolve the issue.

Thanks,
Raja Pothuraju.

Hello

Thank you for the response.

I am using this API - https://graph.microsoft.com/v1.0/me/events?$select=subject,body,bodyPreview,organizer,attendees,start,end,location

I am accessing the above API through Guzzle and Postman. However, I get the same response error that I mentioned above.

Fyi, I am not subscribed to a Microsoft 365 account license. However, I have a free Microsoft 365 development program subscription.

Do you think that could be the reason for the above error?

Please let me know.

Thanks.

Hello @sonali dudhia,

Thank you for your response.

I would like to follow up with you offline to better understand the scenario. It seems you're making a Graph call to retrieve user details, but to fully grasp the situation, we need to examine the token and the parameters used when generating the access token.

Please send me an email at 'AzCommunity@microsoft.com' with the subject: "Attn: Pothurajur" and include the following details in the email body:

We can connect offline and discuss this further.
