That addin was written using VB6 and is developed and compiled on an
Office/Outlook 2000 virtual machine. I don't use any properties or methods
in that addin that aren't in the Outlook or Office 2000 object models.

All I had to do for support for later versions is maintain tables of what
attachment extensions are restricted in various versions and service packs
of Outlook.

I did have to add a manifest file for installation on Vista, but that has
nothing to do with Outlook.

Hi,

I downloaded your Attachment Options software. And this supports
multiple versions of outlook. How did you create this? Using VSTO? How
did you get it to work on multiple versions, did u use late binding
for connecting to outlook? What language/ide did u use to create this?

thanks
