</VersionOverrides>
</OfficeApp>
But the button is not getting added into ribbon. If i remove the "VersionOverrides" the addin is getting shown in outlook 2016.
So, the VersionOverrides is working but somehow the button is not getting shown inside mail during read and in the list of addins in compose mode.
What am I missing?

Answer 1

Use this sample to grab a manifest, which you can edit to your liking: github.com/jasonjoh/command-demo

Answer 2

The URLs in your manifest need to be reachable. You have a lot that start with remoteAppUrl, and some that are contoso.com.
