Office 365 RRS feed

  • Question

  • I have an application that sends automatic mails to my customers. The Application is developed in Java and hosted on AIX Server. The problem is the application maps mail server with only IP Address and has no place to map SMTP Address. Could someone guide me what public IP, I should map my application to send mail from Office 365.

    You can find all the IP's used inside Office 365. Those IP's might change or removed or even blocked at some point.  

    If the app only supports IP ,Will it work if you use a internal IP which points to office smtp server.
