Use it if you have Office

It's a Microsoft product so there is a wealth of information online both from Microsoft directly and from millions of users but as a corporate user we also have access to direct Microsoft support through a variety of avenues (phone, email, etc.). This makes finding answers to issues more accessible, however, it does also mean that any new feature requests will get buried.

If a coworker asked me what software to use, I would recommend OneDrive because of the company standardization and the integration into Microsoft Office. If someone who didn't already have a standardized software platform asked me then I would probably recommend looking at other options just because I have had hit-or-miss success with the reliability of syncing to the cloud. I use it to sync files between two laptops that I use but there have been a few times where I swapped laptops but the second laptop was missing a file that hadn't synced yet, even though plenty of time was available to sync. It's great for sending large files to people because you can specify their level of activity (download/view only or edit as well).
