Environment

CA Process Automation v4.3 SP05 and up

Cause

"535: 5.7.3 Authentication unsuccessful" is a Microsoft error.  

This error might result after choosing the "SMTP Unsecure" protocol, which is incorrect.  Basic authentication for MS Exchange has been deprecated.  oAuth 2.0 authentication should be used instead.

Resolution

Upgrading to 4.3 SP5 CP08 or 4.4 CP02, will allow configuration of "OAuth" as the mail protocol.
