Our Windows Citrix based application is migrating from Office 2010 to Office 2016 . We have built our application using Office 2016 software. During Server deployment , Infra teams are saying they do not have Office 2016 and they have Office 365 only. Now O265 is cloud subscription and it has Office 2016 . I believe All interop DLL's used are same . Will my application work if we install Office 365 in server ?
Office 365 users may get updates more frequently (depends on the channel chosen), so there can be a difference.
Anyway, your application can work even with earlier interop versions unless new properties or methods (members) are used. There is no requirement to use a corresponding interop version.
