OAuth2 with Microsoft ClientID / Secret Expecting Mailbox

Tcalp

Hi Guys,

I'm trying to setup OS Ticket against of Office 365 organization. I've been able to get a mailbox running, but as soon as I try to add a second mailbox using the oAuth2 Microsoft Authenticator I'm getting:
Email Mismatch: Expecting Authorization for 2ndmailbox@domain.com not authorizedmailbox@domain.com.

I'm trying to use the credentials that I created initially (client_id / secret / auth urls / etc), do I need to create new api auth credentials for every mailbox separately ? --

No, you simply need to logout of any microsoft sites before getting a token for each email. When you setup the first email and received a token you logged in as that email. Now MS is caching your login and using that automatically instead of asking you to login as the second email. So like I said above you simply need to make sure you are logged out of all MS sites or simply use a new incognito/private/inprivate window each time.

Cheers.
