Send-MailMessage `
    -From "Reporting.Services@accenture.com" `
    -To 'aditi.m.singh@accenture.com' `
    -Subject 'Sending the Attachment' `
    -BodyAsHtml $html_table `
    -SmtpServer 'AMRINT.SMTP.ACCENTURE.COM'

Answer 1

This should work for you. One issue you had is that the variable $dt was never initialized in your script.

param(
    $emailFrom = 'Reporting.Services@accenture.com',
    $emailTo = 'aditi.m.singh@accenture.com',
    $emailSubject = 'Sending the Attachment',
    $smtp = 'AMRINT.SMTP.ACCENTURE.COM',
    $Server = "$Env:ComputerName\MSSQLSERVER01",
    $SQLDBName = 'Master',
    $SQLQuery = @"
        SELECT Distinct
            RL.RoleName,
            USR.UserName
