I was on a remote web session with an engineer and we discovered that the Scheduler UI isn't saving the changed password to the database.
The environment that I use is below.
The steps to reproduce are as follows.
During the Remote Web Assistance Session, we tried a Gmail SMTP server and received the same results.
We also enabled tracing and noticed an error in the event logs which I will attach here.
Please let me know if you need any additional information.
