Microsoft wants you to use OneDrive as your preferred cloud storage. If you’re using Dropbox, they are dangling a whopping 100GB of free extra storage for 1 year. That’s quite a lot considering the standard free Dropbox account starts off at 2GB while OneDrive offers 15GB for new users.
To activate the free storage, you’ll just need to link up your Dropbox account on OneDrive and accept a PDF file to be saved onto Dropbox. Claim your free 100GB OneDrive space here.
