How can I allow access through our router for outlook for the web?

After our router (firewall) hardware went down, we are no longer able to access web outlook from outside our newly configured router.  What did we miss?  Web outlook works within the firewall but not outside.

You need to make sure ports 80 and 443 are open to allow web outlook to operate from the outside.

What kind of firewall is it?

Can you post its config or give details of its setup?
You might also need to create a static NAT, or a route depending on your situation.
Is it cisco router? If yes, then:

Assume you have external address X.X.X.X on your router and your MAIL server has M.M.M.M address.
Add these lines to your router config:

ip nat inside source static tcp M.M.M.M 80 X.X.X.X 80
ip nat inside source static tcp M.M.M.M 443 X.X.X.X 443

Check addresses and ports.
