Here is a simple way to add parameters to an existing command when you do not need nor want to overwrite the function name:

• Create a new function
• Add the new parameter(s) at the beginning of the parameter list
• use “ValueFromRemainingArguments” to collect the parameters you want to send to the original cmdlet; you can name the parameter as you want
• When calling the original cmdlet, use the splatting operator “@” with the parameter name you put last in the parameter list.

Here the example wraps the Send-MailMessage cmdlet in case the SMTP Server is not available, etc in a try/catch blog and whatever the result logs all parameters and the current timestamp into a CliXml file for future handling or retry.
