A Microsoft file hosting and synchronization service.
Reset OneDrive from inside the app, then add the business account again through the profile menu; Microsoft supports using one personal account together with work or school accounts on iOS.^1^
Reset and add the account
Since deleting and reinstalling OneDrive did not help, do not repeat that step.
- Open OneDrive.
- Tap your profile picture/person icon.
- Open Settings > Account.
- Select the account currently shown, then tap Reset. Microsoft documents this as the supported in-app reset for OneDrive on iOS.^2^
- Close OneDrive completely from the iPad app switcher, then reopen it.
- Tap profile picture/person icon > Add account.
- Select the work or school account option if prompted, then enter the business email address and password.
The expected result is that the email field accepts input and the business account appears in the account switcher. OneDrive for iOS permits multiple work or school accounts but only one personal account, so having one private and one business account is supported.^1^
If the email field still cannot be edited
This indicates that the process is failing before OneDrive can validate the business credentials. Use these checks to separate an iPad client problem from an organizational account problem:
- Try signing in to the business account through OneDrive in a browser or another Microsoft 365 app.
- If the business account works elsewhere but OneDrive’s email field remains unusable, record:
- iPadOS version
- OneDrive app version
- A screenshot or screen recording of the inactive field
- Whether the iPad is managed by the company
- Contact the organization’s IT helpdesk or Microsoft 365 administrator. Microsoft directs unresolved work or school account issues to the organization’s administrator.^3^
Ask the administrator to check whether the account is still licensed and enabled and whether device-management or app-protection requirements apply to this iPad. If the device is company-managed, the administrator—not another reinstall—must investigate the applicable access policy.
If the business account also fails in a browser or other Microsoft 365 apps, report that result to the administrator because the problem is no longer isolated to the OneDrive iPad interface.
