Mixing Outlook2000 and OutlookXP units

We have quite a mature add-in product.

In the previous version of Delphi, I think we had the Office 2000 automation components turned on. In the newer one (Seattle) we have changed to using Office XP. As a result, without us noticing, we have ended up with both Outlook2000 and OutlookXP in our uses clause. This has led to the odd namespace collision which we've worked around by changing the order of the units in the uses clause.

But... it feels messy. I thought we could just go through and remove all the references to Outlook2000 (which I think is the older version) but it seems they're not 100% the same - we get an error saying "undeclared identifier: TItems" if we don't have Outlook2000.

Suggestions as to what best practice should be please?

Thanks
Richard

Hello Richard,

Add-in Express is built using Office 2000 components. We suggest that you use Office 2000 components. Of course, you may use Office XP components but this will require that you cast all types that Add-in Express provides from Office 2000 to Office XP.
