SharePoint 2019 – SMTP Authentication

SharePoint 2019 SMTP

Microsoft released the new Version of SharePoint 2019 and within there are several new features like the SMTP Authentication. This feature now allows to connect to SMTP Servers directly from SharePoint. There is no need to use an SMTP relay just configure the Outgoing Mailsettings via Central Administration or Powershell.

Configuration via User Interface

SharePoint 2019 SMTP

Simple and easy. But before SharePoint needs an application credential key. Therefore we need a Powershell script:

$key = ConvertTo-SecureString -AsPlainText -Force “myapplicationcredentialkey”
Set-SPApplicationCredentialKey $key

This has to be done on each SharePoint Server in the farm.

Configuration via Powershell

Open the Powershell App and use this script:

$CentralAdmin = Get-SPWebApplication -IncludeCentralAdministration | ? { $_.IsAdministrationWebApplication -eq $true }
$SmtpServer = “smtp.Server.com”
$SmtpServerPort = 587
$FromAddress = “user@example.com”
$ReplyToAddress = “replyto@example.com”
$Credentials = Get-Credential

Set-SPWebApplication -Identity $CentralAdmin -SMTPServer $SmtpServer -SMTPServerPort $SmtpServerPort -OutgoingEmailAddress $FromAddress -ReplyToEmailAddress $ReplyToAddress -SMTPCredentials $Credentials

After that you can use the outgoing email function.
