But I found, after lots of trial and error on my end, a way that I believe is the easiest to reset OneDrive back to default so that you can get up and running again. Anyway…during these few weeks, I had issues not only syncing my corporate and personal OneDrive accounts – yes, you can have two running at once – but sometimes OneDrive would just hang with an error message or two that I couldn’t seem to get rid up. (Side note: I had to reset my Keychain because of Office365 and enterprise single-sign-on issues – I believe this may be related to my OneDrive issues as well but that is unconfirmed). Long story short, I had to reset my Keychain and that seems to have caused some unintentional issues for various things including OneDrive. For the past couple of weeks, I have been battling some issues on my Mac.
