Identity API not supported at Windows Outlook Client (Office.js)

[Bjoern01]

Describe the bug I am using the "getAccessToken" function inside my Outlook Add-in (Office.js). At the OWA it works but on the Windows Native Client an exception was thrown:

{code: 13012, message: "Die API wird in dieser Plattform nicht unterstützt.", name: "Nicht unterstützte API."}

At the requirements for the identity API (https://docs.microsoft.com/de-de/office/dev/add-ins/reference/requirement-sets/identity-api-requirement-sets) the declared support for the Windows Native client with an Office 365 subscription is 2008 (Build 13127,20000) or newer, my current version is 2101 (Build 13628.20274)

To Reproduce Steps to reproduce the behavior:

1. Create an Outlook Add-in with Office.js
2. Call the method 'getAccessToken'
3. Install and open the add-in at the Windows Native Client
4. Use the Add-in until the 'getAccessToken' function has been executed and see the error at the console inside the Edge DevTools Preview that are attached to the Add-in

Expected behavior The same behavior as the OWA, don't throw an exception and return a bootstrap access token that can be exchanged with the "on behalf of" flow at the Azure OAuth2 token endpoint.

• Browser OWA -> Chrome | Native -> Windows Outlook Client 2101 (Build 13628.20274) (Edge version 44.18362.449.0)
