Can't get Onedrive to stop running on my computers

I don't want OneDrive on my computer.  I have no need for it.  I am currently switching from my desktop computer to my new laptop.   I have gone to the Onedrive cloud icon on my taskbar on my new laptop and told it to unsync many, many times. Currently on my taskbar it has the line through it.   When I look at Microsoft storage in settings, it shows that I have used 100% for Onedrive, yet I have unsynced it. My new laptop doesn't have any pictures in the picture folder.  Is it trying to sync with  my pictures on my desktop?  I have a 1TB hard drive, I don't need Onedrive.    IS IT TRUE MICROSOFT WON"T UNINSTALL IT?  I really need some help please.  Because of that, it has totally  messed up using Outlook for my email and keeps telling me I can't SEND and in 19 days I can't receive email.  

Can you see what is inside the OneDrive that is supposedly full of files?

And of course it wants me to buy more storage.
