Microsoft is phasing out Basic authentication in Exchange Online. This change will impact our customer's SMTP settings. Due to this, emails sent from Atera might not appear to be sent from the correct email address... Instead, they will appear as being sent from email@example.com
Note: For a seamless email experience and to ensure your messages retain their authenticity, we recommend transitioning to DKIM. Learn more
You can make sure that Basic authentication is still enabled by running a PowerShell command in Exchange Online.
Connect-ExchangeOnline -UserPrincipalName firstname.lastname@example.org
Get-TransportConfig | Select SmtpClientAuthenticationDisabled
Set-TransportConfig -SmtpClientAuthenticationDisabled $False
For more details about the deprecation for basic Authentication for Exchange Online, please see the following articles from Microsoft.
