Issue/Introduction

Customer is trying to configure OAuth mailbox connection to Azure

When trying to generate the Oauth token using Admin Consent, the admin user can authenticate, then the mailbox user is authenticated.

The issue is that the Access Token is not generated.

There is only a blank page displayed after the mailbox user is authenticated

The usp_mailbox does not contain the access token

jsrvr.log shows that the connection is not being made:

Exception occured while processing: java.net.Connect.Exception: Connection timed out: connect

Environment

Release : 17.3

Resolution

After ensuring all traffic is allowed to Azure the token was generated

Reference the following Microsoft link:

For this specific case, we allowed traffic to *.auth.microsoft.com over ports 80 and 443
