Event log exposes password when not using Run As Accounts

[BetaLyte]

I noticed the event error log is currently leaking the password of the SCSM Run As Account, as it's being printed out if the email validation fails:

Looks like this occurs given the following:

• Using Exchange Online
• Not using Run As Accounts/getting the password into the script by some other means

In any case, much appreciated and thank you for the pull request 👍

I was a bit too quick to close this. I merged this into dev and will keep this issue open for the sake of transparency.
