Hi,
I have created an Outlook 2013 custom ribbon add-in (vsto) which works just fine. I can open an e-mail and my add-in tab is active and can do stuff.
I now save an e-mail as an .MSG and later double-click on it. It is then opened in an inspector even if Outlook is not running which is exactly what I want. But, and this is the problem, Outlook deactivates my add-in and my ribbon tab is gone. I now have to go to manage com add-ins and re-activate my add-in.
Is there somehow a way to open the message without deactivating my add-in?
Thanks in advance,
Gerry.
