This is going to be a short rant.
Why are Office and OneDrive apps so unoptimized?
If you download Office installer it constantly nags you update the Office apps. Daily. Even when you select that you will check for updates manually it still starts and nags to make updates.
OneDrive application is a complete POS. It wan’t to sync everything and it hangs all the time. Naturally, it is better on Windows, but it is so heavily integrated into the OS that it’s hard to tell if you’re storing your files locally or in the cloud.
I think overall Microsoft 365 is a great value of products. Word and Excel are in its own class, and OneNote has it’s uses. But the optimization of all these applications is lagging behind its competition and keeps up Microsoft reputation of buggy software.
