MicrosoftMicrosoftDiana_Vank Trying to settle a discussion with some of our team. The discussion is whether basic authentication to Office 365 will be unaffected by Microsoft's OAuth/AppID change.
On a Poly(com) VVX/Trio UC device when authenticating to Office 365:
1. Modern Auth is used by the "Web Sign-In" feature and https://aka.ms/sphone application.
2. Basic Auth is used when entering credentials via the web browser/server interface option Settings->Skype for Business Sign-in.
After a firmware update to 5.9.3+, we're expecting devices using method #1 will be forcibly signed-out and users will be required to re-authenticate (with administrator approval of new appID) --- CONFIRMED https://techcommunity.microsoft.com/t5/Skype-for-Business-Blog/OAuth-2-0-and-third-party-application-ID/bc-p/571269/highlight/true#M2122
We're expecting nothing will change with method #2 (phones happily keep basic auth-ing).
Does this sound correct? If not, will edit/remove this post so that false info isn't out there :)
