I have an application which uses Microsoft Outlook 11.0 library. Will this
application work on Outlook 2002 and 2007?

No, yes. You use the oldest Outlook reference you intend to support, so to
work on Outlook 2002 you'd use a reference to the Outlook 2002 library.

How does this work if you intend to deploy an Add In to users who are running multiple versions of Office? I am supporting 2007, 2003 and 2002. But they all have different home locations for the dlls.

No user can run more than one version of Outlook.

It doesn't matter at all where Outlook.exe is located, or where any of the
Outlook related dll's are located.

The addin dll is registered with COM and in a special place in the Office
registration hive and that's not version specific. Outlook recognizes an
addin by that registration and the COM registration on the dll in HKCR
allows Windows to find the classes it needs in the addin dll.
