This sounds nightmarish. One of many reasons I refuse to sign into my Outlook account on Windows, I just know they'll use the excuse of "integration" to completely fuck up my computer with cloud bullshit. I want what's on my computer to stay on my computer, dammit.
I agree, actually it’s quite a turning point for me because I’ve always used Windows and have tried to persevere with Windows 11, but more often than not I’m feeling let down by it.
But if I remember correctly I found a script to remove OneDrive that would first download all of the files locally.
