This is only useful if the application that needs to connect to Microsoft Online resides on the system that stunnel is running on.

With this configuration, stunnel will only listen on the address 127.0.0.1.

If you are in a different datacenter, update to the appropriate values.

The Microsoft Online Server names are for customers in the North America Datacenter.

You can install stunnel on a server or workstation in your environment and configure your devices which don’t support TLS or POP3 over SSL to connect through that server to the Microsoft Online Services.

Stunnel listens for non-SSL connections and converts them to SSL or TLS connections.

The secret is a free application called stunnel.

After doing a bit of research we think we’ve found a good way to get these applications to connect without SSL and on the standard POP3 or SMTP ports! Examples include not being able to connect on a non-standard port, or not having the ability to connect over TLS or SSL. In some cases these applications or devices don’t support the requirements for connecting to Microsoft Online. A common problem that we run across while doing migrations is legacy applications or devices which use SMTP to send mail or POP3 to retrieve mail.
