I am installing Cayosoft Administrator for the first time and so far no issues with settings. However I've gotten to the SMTP setup page in the wizard and I'm a little confused.
It's asking for a credential. Is this supposed to be a mailbox? I did not see a step to assign a mailbox license to our O365 service account that would be used for this software so I cannot tell.
Is a credential required? Because SMTP open relay works in a telnet session or powershell cmdlet when I test it, which requires no authentication and just a connector in o365 to allow/safe-list the server's external IP address. If I wipe out the username and password and hit Test, the password auto-populates with a string of characters.
