Configuring Exchange 2007 for OWA & Outlook

I have a client running Exchange 2007 on SBS2008. Their email is hosted by a 3rd party and their Outlook clients are currently configured to send/receive email through that 3rd party server. But all the email messages are also collected by Exchange on the client server as well.  We are now activating OWA and the POP3 connectors to automatically download all email from the 3rd party host to the client Exchange Server so that the email is always available to OWA. Since the email will now be automatically removed from the 3rd party host server by the POP3 connector, what changes are needed to be made to the Outlook clients so that they point to the Exchange Server instead of the 3rd party host?

Is this just a matter of removing the 3rd party email account from within Outlook and replacing it with an Exchange account for the same user?

Also, does Outlook Anywhere have to be configured to allow mobile Outlook clients to connect to the client Exchange Server when the user does not want to use OWA?

This seems somewhat obvious to me, but I would appreciate some validation before I make changes that result in permanently lost email!

i think u have some misconcepts about the pop 3 mail fetching to Exchange server...

even after you fetch the mail all the emails will passthrough the same service providers pop3 server and the agent application which is fetching the emails wll be act as bridge between pop3 and imap...

here there were 2 things will happens always

part 1 :
 when e-mail is coming from out side it'll go to the pop3 server and pop3 fetcher will copy/move the mail to Exchange server.

part 2:
Mail server will recieve all the emails and moves the mails to specific users mail box.


the rest is you have to publish the Exchange server to access over the inter net ...

ie. rpc over HTTPS ( owa needs SSL) and out look web access.

the practice is having no issue by doing this...u can proceed with this....

becouse Exchange server is different and pop3 server is different.... when mails comes from pop3 server the fetcher will move all the mails to the exchange..

and local mail routing is through local exchange so local mails access will be very fat...

any how all the best
