Question details

Recipients using a SharePoint 'Anyone with the link' share URL are being prompted to sign in with a Microsoft account instead of accessing the document directly.

SharePoint Anyone Link Redirects to Microsoft Sign-In

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Sharing a PDF or other document with external users using the 'Anyone with the link' permission level.
Observed behavior: When the external user clicks the shared link, they are redirected to a Microsoft login screen instead of bypassing authentication as expected.

Before you start

Verify that you have actually selected the 'Anyone with the link' option when generating the URL, and ensure you have sufficient site permissions to share files externally.

Solution 1Recommended

Test the Link in an Incognito Window

Use a private browsing window to rule out issues caused by cached Microsoft 365 credentials in your browser.

Sometimes a browser's cached credentials can interfere with how a SharePoint link routes a user, mistakenly prompting a login. Testing in an incognito window simulates a true external user experience.

Copy the shared link

Locate the file in SharePoint, click the 'Share' button, ensure the permission is set to 'Anyone with the link can view', and click 'Copy link'.

Open a private window

Launch an Incognito (Chrome), InPrivate (Edge), or Private (Safari/Firefox) browsing window.

Paste and test the link

Paste the copied link into the address bar and press Enter to see if the document opens without a Microsoft sign-in prompt.

Tip: If the document opens perfectly in the incognito window, the recipient simply needs to clear their browser cache or use a private window themselves.

Solution 2

Check Organization Tenant Sharing Restrictions

Determine if your organization's Microsoft 365 administrator has disabled external or anonymous sharing.

Frequently Asked Questions

Why is the 'Anyone with the link' option grayed out in SharePoint?

This option is grayed out when your organization's Microsoft 365 administrator has disabled anonymous external sharing at the tenant or site level for security reasons. You will need admin approval to enable it.

Does an 'Anyone' link expire automatically in SharePoint?

Yes, it can. IT administrators can enforce a mandatory expiration limit (e.g., 30 days) for all 'Anyone' links in the SharePoint Admin Center. Once expired, the link will no longer provide access.

Can external users edit documents using an 'Anyone' link?

Yes, if the link is specifically configured with 'Allow editing' checked during its creation, external users can edit the document without needing to sign in to a Microsoft account.
