Fix – AADSTS90002: Tenant ‘xxxxxx’ not found. This may happen if there are no active subscriptions for the tenant.

Problem

Recieived the below error when I try to get Microsoft Graph access token with my Azure AD Application using OAuth 2.0 client credentials grant flow.

Token identity endpoint URL : https://login.microsoftonline.com/xxxxxx/oauth2/v2.0/token

"error":"invalid_request","error_description":"AADSTS90002: Tenant 'xxxxxx' not found. This
may happen if there are no active subscriptions for the tenant. Check with your subscription administrator

Fix/Solution

We need to provide either TenantID (Guid) or Tenant DomainName (ex: xxxxx.onmicrosoft.com) in token identity endpoint URL to get access token. But in my case, I have just provided tenant name alone instead of tenant domain name/tenantId, the problem solved after providing complete tenant domain name.

#Token endpoint URL with tenant domain name
https://login.microsoftonline.com/xxxxxx.onmicrosoft.com/oauth2/v2.0/token

#Token endpoint URL with tenant id (guid)
Token identity endpoint URL : https://login.microsoftonline.com/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/oauth2/v2.0/token
