Partner Connection

Hi all,

We have a 3rd party email filtering solution for incoming emails.

I wanted to setup a partner connection in Exchange Online based on their IP address range. This is so I could enable enhanced filtering.

However if I setup by IP range but don't select "accept only TLS connection" then Exchange won't let me proceed. I don't want to select TLS only just in case we lose legitimate emails.

Is there a way to setup a partner connection based on IP but accept all emails regardless of TLS?

      Thanks. I can see the reason behind this for just the partner connection, but for enhanced filtering, it relies more on the IP address range, so just seems like a disconnect between the two features. Even though one relies on the other.
