My script for sending emails using Office365 with an admin credentials. The script worked about 6 month, ago but recently it has not been working although it has not been changed.

I have tried to remove UseSsl but it did not work.

try { Send-MailMessage -To "[email protected]" -Subject "test" ` -From "[email protected]" ` -SmtpServer 'smtp.office365.com' -Port 587 -UseSsl:$true ` -Credential $Cred -Body "testbody" Write-Host "Message sent to me." -BackgroundColor Black -ForegroundColor Green } catch [System.Exception] { throw $_ }

Here is the exception I get:

Send-MailMessage : Transaction failed. The server response was: 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message.

Found the solution. The credential used does not have permissions to send email as [email protected] in -From "[email protected]"

  • @MichaelHampton I just tried the admin email (the credential used to connect to exchange in the above powershell script) for the -From line instead of [email protected] and that worked. Admin credentials did not have permissions to send email on behalf of (or as) [email protected]. Commented Jan 16, 2019 at 10:34
