  • Exchange 2003 Authentication

    I have tried looking this up, but either I am not finding the right answers to my situation, or I am totally reading them wrong....

    Here is what I am needing to do...

    I have SBS 2003. Everything is working with it. Email is going in and out. I have about a dozen people in the field with laptops that have Outlook 2010 configured with a POP account setup to a third party hosting company.

    I would like to setup Exchange to allow those users to be able to send/receive email through the Exchange server without having to make any changes to the Outlook POP settings. In order for this to work, they have to be able to authenticate with the Exchange server on both the POP server and the SMTP server using their email address of [email protected] and not [email protected].

    Is this possible? If so, what do I need to do on the Exchange server? Is there some instructions? I am not beyond reading, just need pointed in the right direction.

    look into Outlook Anywhere (or, Outlook RPC Over HTTPS.) This is a much, much better solution than using pop3.

    pop3 transmits all passwords inclear text.... there's almost no good reason to ever use pop3 any more.

      It will be impossible to change from an ISP based POP3 system to an Exchange based POP3 without user intervention, due to the different ways that authentication credentials are required.

      Therefore you will have to plan to touch all of those laptops to get them on to Exchange, and as already pointed out, the best way to do that will be to use RPC over HTTPS, which is called Outlook over the Internet in SBS I believe. You will need to run the Connect to the Internet wizard to enable it, if it isn't already.
