We currently have Exchange 2003 and Office 2003. We are planning to upgrade our Exchange to 2010 next month. We will upgrade to Office 2010 later this year so our users will use Outlook 2003 with Exchange 2010 for some time. My questions:

- Will Outlook 2003 work with Exchange 2010 without any reconfiguration?
- Are there any new feature/functionality going to show up in Outlook 2003 after the migration?
- Any other important things to remember when doing the above scenario?

Thanks!

Answers to your questions:

Yes - Exchange will need some tweaks, but there shouldn't be any issues.

New Features - none that will show up in Outlook 2003.

Important things to remember - get your SSL cert right.  Buy a SAN / UCC SSL certificate from somewhere like GoDaddy (about the cheapest) and include the following names:

mail.externaldomain.com (or whatever you prefer to use)
autodiscover.externaldomain.com
internalservername.internaldomainname.local
internalservername

Exchange will / or Outlook will - you can tweak Exchange as it is easier to change the server than all the clients:
