Hi
I have my own outlook add-in developed in C++.

What I have observed is, outlook silently somehow links different email id with different contact name, which is stored there in Autocomplete cache. (I know the solution can be to clear autocomplete cache, but customer doesn't want to do that).

  1. When user selects user in To filed on New Email form/window. Now user double clicks on contact name in To field and it opens Contact Card (either from GAL or from Local Contacts). There it shows two email ids under the same name. While one is the correct email id, other other one is totally unrelated. What can be chances of this happening?
  2. When user sends email, by selecting name which gets displayed in autocomplete list near To field. The email gets sent to two different people. Can this be possible at all? If so, how can it be possible?

    How did you created the add in , are you using mapi. Why not traverse through contact and check the property may be the stored email id is getting overwritten etc or some mapping issue. But doesn't looks like a outlook issue to me. If still issue may be you can check with Microsoft along with outlook version.

    Thanks
