Send-MailMessage

CautionSend mail (obsolete)

Send-MailMessage -To a@x -From b@x -Subject s -SmtpServer smtp

Sends mail over SMTP. Microsoft marks it obsolete because it cannot guarantee secure connections. Avoid it in new scripts; on Microsoft 365 move to Send-MgUserMail (Microsoft Graph).

Examples

Syntax
