cannot log in to outlook account on mobile and iPad

Test the account with Microsoft’s Sign-in Helper from any available computer or another network, because failure in both Safari and Outlook across two devices points beyond a single app installation.^1^

1. Determine whether the account itself is blocked

1. Open the Microsoft account Sign-in Helper and enter the affected email address.
2. Follow the action it reports—for example, password recovery, account verification, or unlocking the account.
3. If possible, also try signing in from a computer or a device using a different connection, such as cellular data instead of the current Wi-Fi.

Microsoft has not published a current issue specifically identifying iPad Safari sign-in failure, so do not assume this is a general outage.^2^

2. Choose the correct account path

Personal account—such as @outlook.com, @hotmail.com, or @live.com:

• Complete the Sign-in Helper recommendations.
• If the password is rejected, reset it through the recovery option it provides.
• If the helper finds no account problem, continue with the Safari and Outlook steps below. Microsoft specifically recommends this tool for personal accounts that cannot sign in to Outlook mobile.^3^

School or work account:

• Contact the school’s IT/help desk immediately, particularly because the mailbox contains time-sensitive exam information.
• Ask them to check whether the account is enabled, has an active Exchange Online mailbox/license, and whether a sign-in or device-access policy is blocking the phone and iPad.
• If self-service password reset is enabled, use the school’s password-reset process; otherwise, only its administrator can restore access. Microsoft directs work or school password issues to the organization’s administrator.^4^

3. If account access works elsewhere, repair Safari authentication

Since Safari currently remains loading rather than displaying a specific credential error:

1. On each Apple device, open Settings → Apps → Safari (or Settings → Safari on older versions).
2. Under Extensions, temporarily disable content blockers or privacy extensions.
3. Temporarily turn off Prevent Cross-Site Tracking, then retry the sign-in.
4. If it still hangs, select Clear History and Website Data. This signs you out of websites and removes saved browsing data.
5. Update iOS/iPadOS. Outlook on the web requires iOS/iPadOS 14 or later, and blockers can prevent Outlook.com from loading correctly.^5^

After testing, re-enable the privacy setting and blockers individually to identify which one interferes with authentication.

4. If Safari works but the Outlook app does not

1. Open the App Store, find Microsoft Outlook, and install any available update.
2. Force-close Outlook and reopen it.
3. If sign-in still fails, delete and reinstall Outlook, then add the account again. Deleting the app removes locally cached Outlook data, but mail stored in the mailbox remains online.
4. For a non-Microsoft mailbox—such as Gmail, Yahoo, or iCloud used inside Outlook—contact that email provider if its authentication fails. Microsoft’s mobile guidance separates those accounts from Microsoft-hosted accounts.^3^

Record the exact error text or error code if one appears. For a school account, provide it—along with the approximate failed-login time—to the IT administrator so they can locate the corresponding sign-in event.
