VSTO Outlook - Contact iteration is SO SLOW!
- by DustinDavis
I'm working on an outlook add-in and I have a dialog window that allows the user to select contacts. I havent been able to find a way to use the outlook contact window so I am looping through the ContactFolder.Items and doing my work that way.
The problem is that I have to handle up to 70K contacts. I tried multi-threading and many other things…
