Office 365 Connector issue

[zoohead]

We have just changed our ISP from the SWGFL to M24Seven and had a new Smoothwall Firewall\Webfilter installed.

I am setting up Office 365 as a mail relay for our on premises Exchange 2010 and can successfully send email but cannot receive. I suspect I have not configured the O365 outbound connector properly or it is an issue with the Firewall as our SIP is also not working properly. I just wondered how others had configured their outbound connector, ie have you used a public facing IP for your on premises server or the FQDN.

 

I have made all the required DNS changes and MXToolbox comes back ok.

 

Any advice will be much appreciated.

Are all the required ports forwarded correctly on the smoothwall?

I gave the list of O365 ip's to Smoothwall, so they should have been. Unfortunately this has all been done in a mad panic as we are becoming part of an MAT and we have not had time to do the Smoothwall training yet! I am waiting at the moment for a Smoothwall engineer to contract me.

All sorted. Some additional Smoothwall configuration was required.

Excellent. Their online documentation is pretty good too if you want to save your support credits
