Press Windows key + R

Type "powershell" and hit Enter

Copy & Paste (after editing) this script:

$EmailFrom = “office-365-email-address@your-company.com”
$password = "office-365-email-password"
$username = $EmailFrom
$EmailTo = “your-unsuspecting-test-target@their-company.com”
$Subject = “The subject of your email”
$Body = “Testing Office 365 email...Please reply...”
$SMTPServer = “smtp.office365.com”
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($username, $password);
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)

Once triggered, confer with your willing test recipient to verify that they received the email. SMTP logs can be checked within Exchange Admin, and/or on the recipient's email server.
