Hi, I have an outlook addin program created in C#..When i run it, Outlook opens..then i have to click a button, to activate my form...I can add contacts with photos in a listbox..everything works fine especially when i create the contacts in this addin...But my problem is, when i create the contacts from within Outlook ..all these contacts should also appear in my form particularly in the listbox sometimes they do appear with photos...sometimes without (this happens mostly when i empty outlook contacts and recreate)..why this kind of inconsistent behavior happens?.
