RE: Separate Remote Assist license
Gary,
The blunt answer is Teams and Remote Assist are two different products.
The question you first have to ask "is there a Teams app for Hololens 2"? And the answer is NO. Is there skype for Hololens 2? The answer is no. Then your asking "well i just want to do a teams meeting through Hololens 2 because its cool".
And the answer would be the HL2 is a business tool where the user likely needs "remote assistance" to work on product with a subject matter expert thus why Microsoft created "Remote Assist" to piggy back the contact list of Teams. Thus businesses need a Remote Assist solution.
However, the "concept" of using the HL2 as the device to log in to a general teams meeting is beyond what the HL2 was envisioned as, I mean nobody could see your face in a teams meeting using the HL2 because its on your head ...or so the thinking goes.
There is a possible work around. Open the web browser in HL2 and open a web version of Teams.
