Why does my Mail App for Office show in Outlook online but not in my installed Outlook Client?

Question

It is showing in my Office 365 Outlook in my browser but not in my installed client.

But in my installed client it looks like this. Ie the app is not showing:

I have looked at managing apps etc but can't find any settings to force it to show in my installed client.

Any ideas?

Here is my manifest:

Please note, this is not a real app but more of a "trying things out" app.

thanks Russ

Answer 1

your manifest is version 1.1, but your Outlook build is not 2013 SP1. Outlook 2013 SP1 builds are 15.0.4569 and higher. Please update your Outlook client, and then the app will appear!
