Stop ASP.NET SMTP Emails from Appearing in Office 365 Sent Items Without Affecting Manual Sends
We are sending Emails to our clients through an ASP.NET application using the SMTP protocol and using an O365 Account (email address removed for privacy reasons). The problem is that every time a mail (reset password, otp, campaigns, etc) is sent from asp.net application, a copy of that mail is created in the "Sent Items" of the Support mailbox. This is not needed and it is quickly filling our Support mailbox. How to stop this? Is there any setting in the Exchange Server? Please note that the Support mailbox is also used by our company support representative to send resolutions to customers using O365 Outlook Web Access. The mails send by the representative are very much needed in the sent items. It's only the ASP.NET-sent mails that we want to prevent in the "Sent Items".
