Following PowerShell Module provides different approach to scheduling password notifications for expiring Active Directory based accounts. While most of the scripts require knowledge on HTML... this one is just one config file and a bit of tingling around with texts. Whether this is good or bad it's up to you to decide. I do plan to add an option to use external HTML template if there will be requests for that.
Why do you think that https://github.com/EvotecIT/PSWriteHTML is a good alternative to PSPasswordExpiryNotifications
