How to test Office 365 SMTP server using PowerShell

by

Office 365 supports SMTP relay for authenticated accounts using TLS encryption.

Testing SMTP access is traditionally done using Telnet, but that’s not always an option when using Office 365 due to the authentication requirement.

Fortunately it’s easy to use PowerShell to accomplish the same thing.


How to test SMTP server using PowerShell:

Capture and store the Office 365 credentials for the account you intend to use for SMTP auth:

$msolcred = get-credential | save the credential of from address

Use the stored credentials to send a test message from [email protected] to [email protected], over port 587 (Encrypted w/ SSL):

Send-MailMessage –From [email protected] –To [email protected] –Subject “Test Email” –Body “Test SMTP Relay Service” -SmtpServer smtp.office365.com -Credential $msolcred -UseSsl -Port 587

2. Log in to Administration Center for domain in BPOS-S and create a contact for the email address to whom you want to forward emails.

3. Launch the ‘Migration Command Shell’ from your programs folder.

4. Use the below cmdlet to set external forwarding.

Set-MSOnlineAlternateRecipient -Identity <email address of your hosted account> -AlternateRecipient <email address to forward to> -DeliverToBoth $true

Example: Set-MSOnlineAlternateRecipient -Identity [email protected] -AlternateRecipient [email protected] -DeliverToBoth $true

*Note: The ‘$true’ on the end means it will leave a copy and forward. Change to ‘$false’ and it will only forward and not fill up mailbox.

*Note: If you want to remove a forwarder:

Clear-MSOnlineAlternateRecipient -Identity <email of hosted account>

Example: Clear-MSOnlineAlternateRecipient -Identity [email protected]
