#Office365 was officially launched ‎on June 28, 2011. At the time, I was already (since 2008) working in the Microsoft cloud by subscribing to a Hosted Exchange account, which included Exchange and SharePoint. But as you can see, I jumped on board with the Office 365 platform about 6 months later (over 7 years ago). Back then, OneDrive was called SkyDrive with just 25 GB of storage space.
