How to Fix SharePoint Library Access Email Works but User Cannot Open It

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Attempting to access a shared SharePoint library or file using an email invitation link sent to an external or internal user.
Observed behavior: The sharing email is received successfully, but clicking the link results in an error or prompts the user to request access instead of opening the content.

Before you start

Ensure you have site owner or SharePoint administrator privileges to modify external sharing settings and manage user permissions.

Solution 1Recommended

Enable External Sharing in SharePoint Admin Center

Adjust the tenant or site-level settings to ensure external sharing is permitted, which is often the primary reason external users cannot open shared links.

If the SharePoint site is configured to prevent sharing with external users, invitations sent to outside accounts (like Gmail) will fail when clicked, even if the email arrives successfully.

Access SharePoint Admin Center

Locate Site Policies

Go to 'Sites' > 'Active sites', select the specific site you are trying to share from, and click on the 'Policies' tab.

Edit External Sharing

Click 'Edit' under External sharing and change the setting to 'New and existing guests' or 'Anyone', depending on your organizational requirements.

Save and Test

Save the changes, generate a new sharing link, and send it to the test user to verify access.

Enable External Sharing in SharePoint Admin Center

Admin Privileges Required: Only organization tenant administrators can change these overarching sharing policies in the SharePoint Admin Center.

Solution 2

Verify User Sign-In Account via Private Browsing

Ensure the user is signing into SharePoint with the exact email address that received the sharing invitation.

Solution 3

Check Library Level Permissions and Recreate the Link

Verify that the specific user has the correct permission level for the library and generate a fresh sharing link.

Frequently Asked Questions

Can a user with Read permission view document version history in SharePoint?

Yes, standard users with Read permission can view a document's version history and open previous versions. However, they cannot restore or delete past versions; at least an Editor or Contributor role is required for those actions.

Why is the 'Anyone' link greyed out in my SharePoint sharing settings?

The 'Anyone' option is usually greyed out because your organization's tenant-level or site-level administrator has restricted external sharing to prevent anonymous access. You must contact your IT administrator to enable 'Anyone' links for the site.

How do I fix the 'Request Access' loop for an external user?

This happens when the browser automatically authenticates using a different cached Microsoft account. To fix this, ask the external user to clear their browser cache or use an Incognito/Private window, then sign in with the exact email address that received the original sharing invitation.
