I have a finance package being hosted on Windows Server 2016 that can send quotes etc direct to clients by email.
My email account is set up using outlook365 (online) and I also have Outlook 2016 install on this server.
The Outlook 2016 client runs fine on the server, I can send and receive email via my online outlook 365 account.
However, I am having trouble sending email from the finance package. When I use the server settings I found online for outlook 365 I keep getting a "Host Not Found" error from the software.
What do I need to do to be able to connect with the outlook email server? Do I need to enter something else that uses a localhost type address that outlook client must be using or do I need to install some form of smtp server on the Windows server machine to be able to send?
