Upload, work with and move files the same way in OneDrive for Business in the iOS app as you do with your personal OneDrive. To learn more, see Find and work with OneDrive files in iOS.
Add a OneDrive for Business account
You can add a OneDrive for Business account to the OneDrive app for iOS, if your organization uses OneDrive for Business.
Open the OneDrive app and tap the person icon at the top of the screen.
Tap Add OneDrive for Business.
On the sign-in screen, enter the email address and password you use for your company, school, or other organization.
When your organization uses SharePoint 2013 or SharePoint Server 2016, the sign-in process is different from Office 365. On the sign in screen, tap Have a SharePoint Server URL? Then enter the web address of your SharePoint server to continue the sign-in process. The web address, also known as a URL, may look like http://portal.
For you to sign in to OneDrive for Business, your organization needs to have a qualifying SharePoint Online or Office 365 business subscription plan. Or your organization needs to have its own SharePoint Server deployment.
You cannot sign in with multiple OneDrive for Business accounts from the same organization.
If you have a problem signing in with your OneDrive for Business account, try signing in at https://portal.office.com/onedrive or contact your organization's IT department.
Switch between accounts
To switch between a personal OneDrive account and a OneDrive for Business account, or between multiple OneDrive for Business accounts, open the app, tap the person icon at the top of the screen, and then tap the account name you want to use.
You can add only one personal account to the OneDrive app. To open a different personal account, tap the person icon at the top of the screen, tap the Information icon next to the account you want to sign out of, and then tap Sign Out of This Account. Then, sign back in with the account you want to use.
Use a passcode
You can set a four-digit passcode to prevent other users of your iOS device from accessing your OneDrive for Business account. To do this, open the app, tap the person icon at the top of the screen, tap Settings , and then tap the Passcode toggle to turn it on and to enter your passcode.
