outlook.com web 插件 | 如何在顶部功能区上显示加载项

Question

I working on building an add-In for outlook.com (web version). It perform some action on emails. Currently it works with single email ie when you are reading an email, i click on the "..." menu and i can see my add-In there.

However i am facing 2 issues:

1. how to display add-on on the ribbon (see screenshot below)? is it possible? currently it is visible only in email read panel.
2. I want to perform the same task on multiple email selection ieuser can select multiple emails and then click on my add-in (for this add-in needs to be present in ribbon ie question#1).

what I know so far is, "ExtensionPoint" is the property that defined where add-in will apear which currently can be set as MessageReadCommandSurface or MessageComposeCommandSurface but this display add-in on single email level

Answer 1

1. You can pin the add-in to Message window (quick actions) using

    settings -> Mail -> Customize actions -> Message Surface/Toolbar

   You can choose the surface (based on add-ins availability on that surface) to show the add-in individually. Visit here to find more.

2. Currently the feature of enabling add-ins on multiple selected mails is not there. We track Outlook add-in feature requests on our user-voice page . Please add your request there. Feature requests on user-voice are considered, when we go through our planning process.
