AADSTS700016: Application with identifier ‘xxxxxxx-22a3-4ef6-xxx-862cc3eb1733’ was not found in the directory ’Customers AD name’.

Endpoint / Log: 

• Any auth endpoint
• API Logs 

  Error renewing access token

Causes

• Wrong client_id
• Application not approved by the mail administrator

Resolution

•  If this happens for all customers with account on Office 365 trying to authenticate then ensure the identifier is the Azure client_id - it should be in the format shown in the code block above. A common mistake is copying the wrong value.
• If this happens for specific customers then the customer needs to approve the application via Admin Approval.  The mail administrator may wish to improve their approval process to provide a admin consent screen instead of returning the above error.
