Output array to email body

I have the following script and all is working (thanks to advice from this site and Craig Duff). I am now attempting to add a final piece that emails the results. The issue I am having is that I can't get the format of the email body correct.

I have tried out-string and format-table with no luck.

The goal is to write to the body of the email the list of users ($user.name) and the the machines ($comp) that were added to the user's LogonRestrictions attribute. In a nice readable table / format.

Any ideas????

$ReportList = @()

$users = $items | Group-Object -Property UserID
