If you’re like me and you use several different OneDrive accounts, you can now access all the files in your multiple OneDrive accounts on your phone by adding all your accounts on the OneDrive App.
Open up the OneDrive App > tap the three horizontal bars found at the top left hand side of screen. Then tap the “Add Account” button (you can see in the screenshot below that I currently have two different OneDrive accounts set up to use on the phone).
Input an email address for your next account in the space provided and tap the blue Next button. Then input the password for the next OneDrive account in the space provided and tap the blue Sign in button.
The OneDrive app will now be signed into that account and you can view and work with the files and folders in the newly added account. You can toggle between the various accounts that you’ve set up in the OneDrive app by opening the app, then tapping the three horizontal bars found at the top left hand side of screen to get to the accounts screen. The screenshot below now shows the three accounts that are set up on my phone.
