Microsoft has rolled out a nice new Office.com portal user experience for it Microsoft 365 commercial customers. There’s no announcement yet, so it’s not clear if or when this change is coming to Microsoft 365 consumer users. But I assume it is.
The new portal was first spotted by Aggiornamenti Lumia, but I checked with my own Microsoft 365 commercial account, and am seeing it as well. The new interface puts recent, pinned, and shared documents up-front and center and moves the Office app shortcuts to a left-mounted side-rail. You still open the app launcher by clicking a button in the upper-left of the interface.
Looks great to me.
