ActiveSync not working for mailbox moved from Exchange 2003 to 2010

I am moving from an Exchange 2003 server to Exchange 2010. I did a local move of my mailbox and email is working fine. But, I no longer receive emails on my android phone via activesync. I have checked the box on my account to include inheritable permissions in active directory and I have configured an Exchange ActiveSync Policy on the new exchange server. I can't connect to the server though. Can I use ActiveSync in this type of environment or do I need to move all the mailboxes before Activesync works?

have you set external URL on active sync virtual directory on exchange 2010?

Otherwise phone cannot reach to your exchange server from internet

If you have corporate wi-fi, try from there to connect phone to active sync, it should work

found it. Yes an external URL is set up. It is HTTPS:// I haven't changed anything on the phone. It still has the Exchange 2003 Server name in the setup of it.
where pointing?
On exchange 2010?, it should..

Also your mailbox should remain on exchange 2010 server

So do I need a static IP for this?
can you check your IIS logs on the CAS server to see if you are reaching it ?
Are there any reverse proxies or other equipment that maybe has not been modified with the coordinates of the new server ?

Did you try the Microsoft Remote Connectivity Analyzer ?
MaheshArchitectCommented: should point to exchange 2010 server and it should be published on Internet
Then try configuring active sync on mobiles

sorry for the delay. It took Comcast a week to get me new static IP's since I only had one. Once I set up the new static IP for the new server and published it, it worked. Thanks for everyone's efforts.
