Fix OneDrive Anyone Links Requiring Microsoft Account Sign-In

Question details

Users are experiencing an issue where OneDrive folder links set to anonymous access are unexpectedly prompting recipients to sign in with a Microsoft account.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Sharing OneDrive folders with external users, students, or clients who do not have a Microsoft account.
Observed behavior: Links previously configured to allow anonymous access (Anyone links) now incorrectly require recipients to authenticate with a Microsoft account before viewing the contents.

Before you start

Before troubleshooting, verify that the recipient is not accidentally opening the link in a browser where a different Microsoft account is already logged in, as cached tokens can sometimes trigger authentication conflicts.

Solution 1Recommended

Regenerate the Sharing Link and Test in Incognito Mode

Create a fresh link and test it without cached credentials to rule out browser-specific authentication glitches.

Generate a new link

Go to your OneDrive account and locate the folder you want to share. Click the 'Share' button, ensure the permission is set to 'Anyone with the link', and generate a new sharing link.

Open a private window

Open a new private or incognito browser window to ensure no previous Microsoft login sessions are active.

Test the new link

Paste the newly generated link into the address bar to verify if it allows access without prompting for a sign-in.

Instruct the recipient

If the link works for you in incognito mode, ask the recipient to clear their browser cache or use an incognito window when opening the link.

Browser Cache Issues: Sometimes old session data forces Microsoft servers to attempt an automatic sign-in, which results in an error or a prompt for anonymous users.

Solution 2

Share Individual Files Instead of the Entire Folder

If folder sharing continues to force sign-ins, sharing specific files often bypasses this bug.

Solution 3

Review Microsoft 365 External Sharing Policies

If you are in an enterprise or educational environment, backend policy changes might be overriding anonymous links.

Frequently Asked Questions

Why do my OneDrive 'Anyone' links suddenly ask for a login?

This is often caused by a temporary backend glitch in Microsoft's servers, a recent change in your organization's IT sharing policies, or browser cache issues on the recipient's device conflicting with Microsoft account tokens.

Can I share a OneDrive folder without requiring the recipient to have a Microsoft account?

Yes, by generating an 'Anyone with the link' URL. If it forces a sign-in unexpectedly, try regenerating the link, sharing the individual files instead, or asking the recipient to open the link in a private browsing window.

How can a Microsoft 365 admin check external sharing settings?

Your administrator can access the SharePoint Admin Center, navigate to the 'Policies' section, click on 'Sharing', and verify that the external sharing permissions for OneDrive and SharePoint are set to 'Anyone'.

Does clearing the browser cache fix OneDrive sharing link issues?

Yes, clearing the browser cache or opening the link in an incognito window removes saved authentication tokens that might mistakenly force a Microsoft sign-in prompt.
