    SMTP Authenticated Emailing for Microsoft and Gmail

    Please Note for 2-Factor Authentication:
    For institutions that have 2-Factor Authentication enabled for their Microsoft Office 365 accounts, Please follow the steps at this page in order for email authentication to be successful: Multi-Factor Authentication Email (2FA/MFA)


    Microsoft Server email relay platform has begun rolling out blocking outbound SMTP connections on TCP port 25. Microsoft claims this is to ensure better security for Microsoft partners and customers, protect Microsoft’s Azure platform, and conform to industry security standards. 

    What this means is that in order to prepare for email out of the Campus Cafe system in the near future when Microsoft completely cuts off the use of port 25, each user that will be using the email functions from their address will need to input their password into their email record on their account, and unauthenticated email aliasing from a domain will no longer be acceptable.

    In order to prepare for this change we have added new "User Specific" SMTP Authentication configuration.
