Error when configuring the Coordinator to use Office 365 for the SMTP configuration: ""The SMTP server requires a secure connection or the client was not authenticated" -
Descrizione
After configuring the Coordinator to use Office 365 (smtp.office365.com) for the SMTP server and clicking Test SMTP the following error occurs: "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [O365ServerName.prod.outlook.com]." -
Risoluzione
Run the following Powershell command on the Coordinator to test sending mail to O365:
$msolcred = get-credentialSend-MailMessage –From <FromAddressEnteredOnTheCoordinator> –To user@yourcompany.com –Subject “Test Email” –Body “Test Text” -SmtpServer smtp.office365.com -Credential $msolcred -UseSsl -Port 587Enter the credentials specified in the Coordinator SMTP Configuration under the section 'My Server Requires Authentication'. Also test by using -Port 25 instead of -Port 587.If you get the same error, the issue is most likely with either the credentials you are using or the From address. Try specifying the credentials using an @onmicrosoft.com account.
