Few weeks ago, I took over the development of the Outlook VSTO add-in. The entire view is designed in WPF. Since Office has been updated from 2013 to 2016 they have appeared some troubles with pasting text into a textbox. I have a button on the Outlook's ribbon in writing email mode, which one display my custom window with two textboxes. When I am focusing on one of textboxes, I can typing there whatever I want. The problem is in case I am trying to paste text. The copied text is pasted into a "To" field in the window in background, even if I am focused on my textbox in my window from my add-in.
Do you know anything about similar problems after Office upgrade?
