A Microsoft file hosting and synchronization service.
Good day Alexander,
Just to gently clarify before going any further, this forum is separate from Microsoft Support. I don’t have the ability to access or investigate individual accounts or escalate the issue directly Microsoft Support because this is a user‑to‑user support forum.
The OneDrive app on iPad supports both a personal account and a work or school account, so having both accounts signed in is supported. Since the work account disappeared and the email box doesn't allow any typing when you try to add it back, please try the steps below:
Option 1: Check the keyboard
Open Safari or Notes.
Confirm that you can type normally.
If you use a Bluetooth keyboard, disconnect it temporarily.
Return to OneDrive and try the email field again.
This helps confirm whether the issue is related to the keyboard or the OneDrive sign-in screen.
Option 2: Test the work account in a browser
Open Safari > Sign in at https://onedrive.cloud.microsoft/using the work account.
If the account signs in successfully, the account itself is working and the issue is limited to the OneDrive app.
If the account cannot sign in through Safari, please contact your organization's IT administrator to verify the account status and credentials. In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
Option 3: Check with your organization's IT administrator
Because this is a work account, I recommend contacting your IT administrator to verify that the account is active, a license is assigned, the iPad meets any or requirements, any required apps such as or are installed, and no policy is blocking access to OneDrive.
Option 4: Contact Microsoft Support
If the account works in Safari, the administrator confirms that no policy is blocking access and the email field still doesn't accept input, the issue will require investigation within the Microsoft 365 environment.
In that case, your IT administrator can create a support request through the Microsoft 365 admin center > Support > Help & Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.
I wish I could help more directly, but as a fellow user in this community, providing these steps is the best support I can offer. If you have any updates or additional questions, feel free to reply back and I'll do my best to assist further.
