How to Fix Repeated iCloud Password Prompts After Microsoft 365 Reinstallation
Question details
The user is experiencing repeated prompts for their iCloud password on Windows even after reinstalling Microsoft 365, which interrupts their workflow and affects Excel files.

- Product
- Microsoft 365 / iCloud for Windows
- Device & OS
- Windows
- Scenario
- Using Microsoft 365 alongside iCloud on a Windows computer.
- Observed behavior
- Windows continuously asks for the iCloud password, interrupting daily tasks, and Excel folders occasionally fail to open correctly.
Ensure you know your Apple ID and password, and have access to a trusted Apple device for two-factor authentication before modifying your iCloud account settings.
Clear Credential Manager and Re-sign into iCloud
Clearing outdated or corrupted iCloud credentials from Windows is the most effective way to stop recurring password prompts.
Windows stores login information in the Credential Manager. When these credentials become corrupted or out of sync with Apple's servers, it triggers repeated password requests.
Press the Windows key, type 'Credential Manager' in the search bar, and select it from the results.
Click on 'Windows Credentials', locate any saved entries related to iCloud or Apple, and click 'Remove'.
Open the iCloud for Windows app, click 'Sign Out', and then restart your computer to clear temporary cache.
After restarting, open iCloud for Windows and sign back in. Use an app-specific password if you have two-factor authentication enabled on your Apple ID.

Update Windows and Reinstall iCloud
Running outdated versions of Windows or the iCloud application can cause persistent integration issues with Microsoft 365.

Frequently Asked Questions
Why does Microsoft 365 keep asking for my iCloud password?
This usually happens when the saved login credentials in the Windows Credential Manager become corrupted, or when Apple's security protocols require an app-specific password for third-party integrations.
What is an app-specific password and how do I get one?
An app-specific password is a unique, one-time generated password that allows non-Apple apps to securely access iCloud. You can generate one by logging into appleid.apple.com, navigating to the App-Specific Passwords section, and selecting 'Generate Password'.
Will reinstalling Microsoft 365 fix the iCloud prompt issue?
No, reinstalling Microsoft 365 typically does not resolve this issue because the credentials and sync conflicts are managed by the iCloud for Windows app and the Windows Credential Manager.
