Question details

Administrators and users are unable to open SharePoint and are instead being redirected or caught in a continuous sign-in loop.

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: A user or global administrator with a Microsoft 365 E3 account attempts to access SharePoint.
Observed behavior: The user is unexpectedly redirected to the Microsoft 365 home page or is repeatedly prompted to sign in without successfully loading SharePoint.

Before you start

Ensure you have access to the Microsoft 365 Admin Center with global administrator privileges to verify and manage active user licenses.

Solution 1Recommended

Verify and Assign the Microsoft 365 E3 License

Ensure the correct license is actively assigned to the affected account, as missing or pending licenses frequently cause access redirection.

SharePoint access requires an active license assignment, even for users holding global administrator roles. Reassigning the license and waiting for server propagation is often the most effective fix.

Access Active Users

Select the Affected Account

Search for and select the specific user account that is experiencing the SharePoint sign-in loop or redirection.

Assign the License

Navigate to the 'Licenses and apps' tab in the user properties panel. Ensure that the 'Office 365 E3' or 'Microsoft 365 E3' license box is checked, then save your changes.

Wait for Propagation

Sign out of the account completely. Allow up to 24 hours for the license changes to fully propagate across Microsoft's servers before signing back in.

Propagation Time: While licenses often apply within minutes, backend synchronization for SharePoint services can sometimes take up to 24 hours to take full effect.

Solution 2

Clear Browser Cache and Check Roles

Remove outdated browser session data that might be causing a persistent login loop and verify there are no conflicting administrative roles.

Frequently Asked Questions

Why am I caught in a sign-in loop when opening SharePoint?

A sign-in loop usually occurs when your browser's cookies are corrupted, your session has expired, or there is a delay in the Microsoft 365 license propagation. Clearing your browser cache or using an Incognito window can often bypass this issue.

How long does it take for a Microsoft 365 E3 license to activate for SharePoint?

After assigning a Microsoft 365 E3 license in the admin center, it typically activates within a few minutes. However, it can occasionally take up to 24 hours for the changes to fully propagate across all Microsoft services, including SharePoint.

Can a global administrator lose access to SharePoint?

Yes, even a global administrator can lose access or face sign-in loops if they are not explicitly assigned a valid SharePoint or Microsoft 365 license, or if there are conflicting administrative roles applied to their specific account.
