Hi,
I developed a simple Outlook AddIn in Visual Basic 6.0 (referencing
MSOUTL.OLB of Outlook 2003). The AddIn just use simple methods that are
compatible between the different Outlook versions.

Will my AddIn DLL work on a machine running Outlook 2000 or Outlook 2007 ?

Depends on what exactly you do.
As a general rule of thumb, you must reference (and hence develop on a
machine with) the lowest suppred version of Outlook; 2000 in your case.

Now I downloaded and referenced MSOUTL9.OLB (for Outlook 2000) on my machine.
But my PC has Outlook 2003. The AddIn compiled and run fine!
