I am trying to use Don John’s Famous Enhanced HTML Report Script to pull some data out of Exchange 2013 Servers, I have created two functions to pull some basic data to test and i got this error message below. When i run the functions by itself they are working fine. I know the HTML requires string, does not like Arrays, Out-string does that but i still get the error below.
Error Message;
