transfer exchagne server 2007 roles

Hi,

      Due to  performance issue, I  create the new exchange server 2007 (ent) on window server 2008 (ent) and transfer  all the mailboxes  from old server to new server and also regenrateand configure  the SSL UCC certificate  
      After  2-3 days I switch off the old exchange ,  now I need to create  some account for our branch office and they will use outlook anywhere (RPC over HTTP) based account.  Brach office users  also not a part of domain users.    My problem is that when I try to configure the branch office user system outlook user rpc over rpc, the  outlook not make connection with server,  I try to find the  solution for 3 days, but finally I start the my old exchange server also than  configure the  the remote users  with this server. And its workign fine.
Now I want to transfer the all roles from old exchange server to new exchange server but also dont want to uninstall the old exchange server also, pls suggest..

Warm Regards,
Naresh

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Did you install CAS role on the new server ?

did you enable outlook anywhere on the new server?

how is your outlook anywhere published to your external users ? have you changed that to point to your new exchange ?

finally I won't advise you to simply turn off the "old exchange" it would be much wiser to uninstall it
