We have built a VTSO office add-in using Visual Studio 2008 (C#,vsto 2.0 runtime) targeting office 2007 as the minimum version. Works fine on 2007 and 2010 version of outlook, word, excel and power point. It is also working on 2013 version of word, excel and power point but do not load on outlook 2013. We do not get any kind of error message. Any help will be appreciated.
Thanks in advance, Vikas
