We just started using SD Plus-on-demand enterprise and trying to use Office 365 shared mailbox under mail server settings but it doesn't work as shared mailboxes(Office 365) don't have a password. If I use my login details, it works fine so we know that the server settings and port numbers being used are correct.

I have tried using the following as I have full access to the shared mailbox

Username: myid@xyz.com\ sharedmailbox@xyz.com

Password: My Password

E-mail Adderss: Shared Mailbox

The above doesn't work and comes up with error. Any assistance would be appreciated. We don't see a reason for giving a shared mailbox full office 365 license
