Question details

External users with Gmail accounts are being prompted to sign in to a Microsoft account when attempting to access a file shared via an "Anyone with the link" URL.

How to Share OneDrive Files with External Users Without a Microsoft Sign-In

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Sharing documents with clients or external partners who do not use Microsoft accounts, expecting them to view the files anonymously.
Observed behavior: Clicking the sharing link redirects the external user to a Microsoft login page instead of opening the document directly.

Before you start

Ensure you have administrative access to the Microsoft 365 and SharePoint Admin Centers, as modifying organizational external sharing policies requires admin privileges.

Solution 1Recommended

Disable the Guest Sign-In Requirement in SharePoint Admin Center

Modifying organizational sharing policies ensures that anonymous links function correctly without requesting a login from external users.

By default, tenant administrators might have strict security protocols enabled that override standard anonymous link behaviors. Disabling the forced guest sign-in allows "Anyone" links to work properly.

Access SharePoint Admin Center

Log in to the Microsoft 365 Admin Center with admin credentials, then navigate to the SharePoint Admin Center from the side menu.

Navigate to Sharing Policies

On the left sidebar, click on 'Policies' and then select 'Sharing'.

Adjust External Sharing Settings

Scroll down to 'More external sharing settings' and expand the menu. Look for the 'Guest must sign in' option and uncheck it.

Save Changes

Click 'Save' at the bottom of the page. Generate a new 'Anyone with the link' URL and test it in an incognito window.

Disable the Guest Sign-In Requirement in SharePoint Admin Center

Security Compliance: Only disable this requirement if your organization's data governance and security policies explicitly permit anonymous access to shared files.

Solution 2

Enable Anonymous Links in the Microsoft 365 Admin Center

Check individual user settings to ensure external sharing is permitted for their specific OneDrive account.

Solution 3

Review MFA and Conditional Access Policies

Strict Multifactor Authentication (MFA) or Conditional Access policies might override standard sharing configurations.

Frequently Asked Questions

Why does my "Anyone with the link" require a login?

Your organization's SharePoint admin settings or Microsoft Entra ID Conditional Access policies may have overridden the default sharing behavior to enforce guest authentication for security reasons.

Can I share a OneDrive file securely without requiring a Microsoft account?

Yes. If your IT administrator has enabled anonymous external sharing, you can generate an "Anyone with the link" URL. For added security, you can set an expiration date or an access password on the link before sharing it.

Do these policy changes affect previously shared links?

Yes. If an administrator disables anonymous sharing or enforces guest sign-ins at the tenant level, any previously generated "Anyone" links will instantly require external users to log in when they try to access the file.
