Dropbox is now making it easier for you to edit files on the go with a new feature for both Android and iOS. The app won’t just let you view documents through Microsoft Office, it will now let you tap the edit button to launch Microsoft’s Office suite (of course you have to have it installed). When you save the changes, this automatically syncs to the cloud as well.
If you are, however, editing files on a Dropbox for Business account, you would need to have one of the following Office 365 accounts: Business, Business Premium, E3, E4, or ProPlus.
