Ken,
I did some digging and here is what I found out. The program that they
developed is not a formal "outlook add-in". It is actually a standalone C++
app that they built which calls the Outlook Object model and gets some
calendar data.

It was exposed to the users in OL2000 and OL2003 by putting an Icon on the
toolbar that called the external .exe.

Is there a way that I can add this to the ribbon in OL2010 (x86 version)?

Thanks,
Steve

Not enough information.

What language? Do they want to support 64-bit Outlook? Do they plan to
support the ribbon? How are they installing and what installer are they
using? Any ActiveX controls or dependencies? Any 3rd party controls? Are any
deprecated Windows OCX controls that aren't there in Vista or Win7 called?

I have some addins written originally for Outlook 2000 that run just fine as
is, others required extensive re-writes or even ports to other platforms.
Without a lot of information there's no way to tell what is required.

All,
I am working with a customer that has an Add-In for Outlook that was
developed for Outlook 2000 and they are currently using it in Outlook
2003.

They are planning to migrate to Outlook 2010 this summer. Can someone
point
me to what they need to know about how to make this add-in install and
work
with Outlook2010?

Thanks,
Steve
