What are the differences between Outlook and Exchange with regard to POP mail?  I would like to use one of them to interface with another app, but don't know the mail systems that well.

Outlook is a client that can access an Exchange server, POP/SMTP, IMAP, CC Mail, .etc and has a good automation object that will allow you to send mail, create contacts, .etc.

The old Exchange client has no object model when it comes to programming, but can still talk to the same types of services as Outlook.  From a programmers point of view you would be reduced to using simple mapi or the mapi ocx controls that come with VB in order to send mail.

Neo: Actually, Microsoft added fairly extensive scripting support to Exchange Server 5.5 SP2, and you can also access an Exchange server via CDO (Collaboration Data Objects) which can be accessed from Visual BASIC, C, C++, etc...

True... but CDO requires that Outlook be installed, not the old Exchange client from Windows Messaging.  See redistribution notes at ;)

Neo_Mvps: Yeah, I know about the Outlook thing--although you could actually run a CDO-enabled application on the Exchange server itself, which always includes the relevant libraries. At least, the one we've got set up here does, and it definitely doesn't have Outlook installed!

Valid and true points, but the comments I made of from a workstation point of view and not at the server.  (ie. I was comparing Exchange client to Outlook client, not Outlook client to Exchange server.  Sorta like the old standby of comparing apples to apples and not apples to oranges.)
