CRM and Exchange access remotely - same ports


We have a SBS 2003 running Exchange.
This exchange is accessable from the internet using outlook remote access.
The exchange is also configured to remotly sync with mobile devices.

Now there is a second Windows 2008 server running CRM. on the same LAN
We need to access the CRM remotly to sync data to a website.
But the CRM also uses port 80 to sync. I can't open two ports on the same IP.

What is the best way of fixing this? Change the Exchange port? or the CRM?
or another solution?

Please be careful with the steps you follow. The KB article suggested is for CRM 4..0 and will absolutely not work for CRM 2011.

Follow this article and you can change port for CRM 2011

and for bindings

Add the Headers value in IIS of CRM application instead of changing the port. Or change the port of CRM. Do not the change the Exchange port as it is not suggestible.
