OWA is web based, it uses port 443.
Activesync (for the phones) uses the same port.

You will need a 3rd party certificate on the SBS server for this to work smoothly.


POP3 is an older way of retrieving email, it has limited functionality, and serious security holes, strongly advised not to use it.

I do have 443 open and there is a cert. But I don't get the exchange login page like you would expect. instead I get and iexplorer login asking for login.

Test it internally. Do you get the same login as from outside?

Want to promote your upcoming event?

Are you going to an event? Are you going to be exhibiting at a tradeshow? Talking at a conference? Using a promotional banner in your email signature ensures that your organization’s most important contacts stay in the know and can potentially spread the word about the event.

no internally it works as it should. I added an ACL for https pointing to the exchange server and it seems to work now. will I need to do anything else for the phones?

No, phones will use port 443.
