Even if its cumbersome, it's still a win-win for them to use it.

The outlook app will be native desktop and mobile (except linux for now).

Plus it will give the maui project more credibility, help grow its userbase. Make the framework better by providing a real world project for the maui team to benchmark, highlighting pain point, provide in-house feedback, feature request.

I would be interested to know from anyone at the Office/Outlook team why they went with what they did, and if they had any awareness of MAUI happening at all. Fully agree with the noted benefits, so any non-MAUI team insight would be really interesting

Has the Office team ever paid that much attention to what Windows was actually recommending?

All the releases that I can think of shunned the standard UI toolkits for their own homegrown UI. Presumably to show the Windows folks that the Office team is it's own little empire.

Excel even had its own custom C compiler.

My guess would be that they're looking for parity with web apps. I have teams installed on my corporate desktop but I just use the web application any other time and it's... identical.

If you want an identical experience with identical code across the Web, iOS, Android, Windows, Mac, Linux then there is only one solution.
