How to send email from Azure automation runbook

Question

Hello,

I am trying to create a runbook in Azure Automation account, that should collect some data and in the end send them via email.

But when I define the "mail send section" like this:

$emailParams = @{
    From       = "******@domain.com"
    To         = "******@domain.com"
    Subject    = "Test Email"
    Body       = 'report'
    SmtpServer = "smtp.office365.com"
    Port       = 587
    Credential = $credential
    UseSsl     = $true
}

Send-MailMessage @emailParams

($credential variable contains Automation account stored credential with Global reader rights, referenced via

$Credential = Get-AutomationPSCredential -Name "Cred name"

I get following error:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 Client not authenticated to send mail. Error: 535 5.7.3 Authentication unsuccessful

Account that I stored within AA credentials has valid password, I can login to portal.office.com under that identity.
What is wrong? How can I send an email from AZ runbook? What is my stored credential missing?

Many thanks,

Tomas

@T Crha Thanks for your query. Kindly note that the Send-MailMessage cmdlet is obsolete. This cmdlet does not guarantee secure connections to SMTP servers. While there is no immediate replacement available in PowerShell for sending email using SMTP server, we recommend you do not use Send-MailMessage.

You can try using Microsoft Graph commands to send the email from automation account. Here are some reference documents to get you started with

No, you don't need a 3rd party when this is possible to do via Graph Send.Mail and using Send-MgUserMail
