I can send emails using smtp.office365.com, port 25, usessl, server requires authentication, but when using the same settings and port 587 I get "transport faield to server".
Port 25 is blocked by many ISPs, and Microsoft recommends using port 587, so would like to use a port other than 25.
Are there required settings for Port 587, or is another port viable?
I am using Access 2010. Windows 10 64 bit.
Thanks
