Here's a question I had after reading the blog post on storing powershell variables within an external text file.
https://www.sapien.com/blog/2018/03/22/ ... nal-files/

After the reading the post, I was also working on a project where I wanted to do the reverse of what the article was talking about and have variables within a text file grab variable values from within the script.

Here’s the scenerio:
I have a list of new mailbox accounts and want to inform all the users of their new email address and credentials (sent to their old email address). I want to utilize a ‘form style’ text document with html formatting for the -BodyAsHtml switch in the Send-MailMessage cmdlet and push variable values into the body of the message. I can successfully include the html formatted message in the body of the message however, none of the variables get populated. There must be away to read the message body first and inject the variable values before sending the message. Question is, how?

Any thoughts?

Example:

Code: Select all

$body = @'
<pre>
    Dear  {0},
     Your free gift of {1} for being a dear customer
     has been shipped on {2}
<\pre>
'@
$body -f 'Jane Dough', 'vanilla cake', '12/31/2031'

The "-f" operator is the string formatter operator and works as a "sprintf" function.
