Oauth for Shared Mailboxes
Idea shared by Artur Rzasa - 9/19/2022 at 10:41 PM

Hi SmarterTrack Devs,
Looking to see if an extra OAuth feature can be added to allow using shared mailboxes. This seems to require an additional mechanism to authenticate, and then replace userName with the email address of the shared mailbox as per below I found on the internet:

In case of shared mailbox access using OAuth, application needs to obtain the access token on behalf of a user but replace the userName field in the SASL XOAUTH2 encoded string with the email address of the shared mailbox. 

The benefit of having this, is that we users can use one license at Microsoft to access multiple shared mailboxes which can be utilised within SmarterTrack. Otherwise, we need to license each mailbox which can get costly when you have a few departments, although they are barely used as it just passes through.

Currently, with POP, we can use for login, emailAddress\sharedMailboxAlias, and the emailAddress password and access the sharedMailbox.

Thanks for considering.

Hey there Art, I just wanted to let you know this is something we're looking into internally. I believe this may already work, and in this case though you'd leverage OAuth to authenticate with the account directly, rather than authenticating under the admin/primary account. I'd like to get some testing set up on this though to confirm, so I may reach out on a ticket if I have any questions along the way. Thanks Art!

Just posting a quick update on this for anyone watching the thread! We were able to get OAuth-based authentication with shared mailboxes implemented in SmarterTrack, and this should be available for download in the near future. With that being said, Microsoft does not support OAuth-based SMTP auth for shared mailboxes and so Authenticated SMTP access to the shared mailbox will still be required for outbound traffic on those accounts.

Thanks Kyle and team.
I can confirm OAuth is working with shared mailboxes on SmarterTrack Free Build 100.0.8334.13654 (Oct 26, 2022) which I'm testing atm.
