What does the company do well? No matter where you are in the world, you can easily access your files, share them with other members of your team and synchronize them for offline use. My company uses OneDrive to share files, since we all work remotely and, as we are all in Windows, it makes the transfer and exchange of files very easy.
What does the company not do well? If you have a personal account of Onedrive (not through your company), you may run out of free space depending on the types of files you store as the videos take up a lot of memory. I'm not sure what the price is to get more space.
What do you wish you had known about the company before using? The biggest scam about OneDrive, which is really the biggest scam about Microsoft in general, is its customer support. Because they are so large and have such a vast library of software products, trying to find specific documentation can be a great challenge.
