Passkey and Outlook Classics - WHY MICROSOFT?

We’ve already rolled out Passkey for some customers, and everything’s been great—no issues at all. Whether it’s with Windows Hello for Business, hardware FIDO2 keys, or the Microsoft Authenticator.

But now, as was bound to happen, we’ve encountered our first customer without Windows Hello for Business who’s using only the Microsoft Authenticator.

When logging into Outlook Classic, only the login window that prompts for hardware tokens appears—it looks completely different. There’s no way to switch to QR code + Bluetooth. Every single Microsoft app and browser can do this; everything works—except Outlook Classic.

Why, Microsoft?

So far, I haven't found a solution (other than WHFB) that works for the client (thanks to the four legacy plugins required in Outlook)
