Without my knowledge or consent, when I plugged in my new Dell computer and signed in to my MS 365 account, all my files were put in a cloud including copies of driver's licenses, passports, and family medical records. I thought okay, I'll just take them out of the cloud, which as we now understand also deletes them from the desktop.
I have gone back and forth about a dozen times in emails with MS techs. Some of their advice caused all of my files to disappear from my computer. I asked repeatedly if there is a way to choose what to backup and got no answer from MS. I've had a tech at my home twice, and he finds there is no way to manually backup or choose what files to backup. We decided to quit onedrive. I now have duplicates of files and paths still pointing to onedrive, so I will have to get more help with this. Research that I have been working on for years has been convoluted and possibly lost due to multiple duplicates.
I've been working from home for over 30 years and have never had problems like this. I'm used to figuring out solutions, but this is beyond absurd. I simply bought a new computer to replace my 10-year-old machine and am now in this nightmare.
