Sending email using ClientCredentialProvider is failing to find tenant guid

Question

I am using Microsoft Identity's OAuth 2.0 support to send email using Microsoft Graph.

Created a personal email account as XXXX@outlook.com. Using this account I login to Azure AD and create a tenant there. Used ClientCredentialProvider (From msgraph-sdk-auth-java) as authorizer trying to send an email to myself. Steps:

1. Created a Tenant account.
2. Created an application and given permission in Graph>Application->Send.email etc
3. Created a Secret key

Below is the error I am getting:

Answer 1

I guess you want to use Microsoft Graph API to send email from your personal account email XXXX@outlook.com.

But when you use this account to login to Azure AD and create a tenant, and use ClientCredentialProvider in your code, the account will be treated as a work account (not personal account) of your tenant.

So when a work account wants to send an email, it will requires an Exchange online license of O365 subscription. You don't have O365 subscription with Exchange online license. That is why you get this error: The tenant for tenant guid \u002706841624-5828-4382-b0a0-XXXXXX87b08f\u0027 does not exist.

If you want to send email from your personal account, it's unnecessary to create an AAD tenant. And you should use Authorization code provider rather than Client credentials provider. Another thing is that personal account requires Delegated permission rather than Application permission based on Send mail permissions. Create an application and give permission in Graph > Delegated > Mail.Send.

Please note it may require the scopes as https://graph.microsoft.com/mail.send instead of https://graph.microsoft.com/.default.

Answer 2

Thanks, Allen for your help. I am able to send and receive emails from my outlook account. Using Authorization code provider 1. Login to Azure AD create an Application in "Application from Personl account". 2. Give permission Graph > Delegated > Mail.Send. 3. Provided Redirect URL as http://localhost:8080/muapp".Note Down all appId,Create a secret Key. 4.Now hit the below URL with the details

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=40fcd457-1807-49e3-8bce-XXXXXX40ca194&response_type=code&redirect_uri=https://localhost/myapp/&response_mode=query&scope=openid%20offline_access%20https%3A%2F%2Fgraph.microsoft.com%2Fmail.send%20https%3A%2F%2Fgraph.microsoft.com%2Fmail.read&state=12345

5. Acquire the code.This code we need to pass in Authorization code provider. 6.Scope "https://graph.microsoft.com/mail.send" 7. Authority "https://login.microsoftonline.com/consumers"

I have one question every time send an email I have to Acquire the code. Is there any Way this will have expiry date etc.???
