How to Fix SharePoint External User Sign-In Is Not Complete Error
Question details
External users are unable to access a SharePoint site due to an incomplete sign-in error, even when external sharing has already been enabled.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Attempting to grant site access and resolve sign-in blocks for an external guest user in SharePoint.
- Observed behavior
- The external user encounters an error stating that their sign-in is not complete, preventing them from viewing or collaborating on the shared SharePoint site.
Verify that you have administrative credentials for both the Microsoft 365 Admin Center and the specific SharePoint site collection before attempting to modify guest account permissions.
Remove and Re-Invite the External Guest Account
Clear the corrupted or incomplete provisioning data by deleting the guest account from both Microsoft 365 and the hidden SharePoint User Information list, then send a fresh invitation.
When an external user's provisioning process gets stuck, simply re-sending an invitation often fails to work. You must completely clear their existing profile from all Microsoft 365 and SharePoint directories before re-adding them.
Log in to the Microsoft 365 Admin Center. Navigate to the Users section, select Guest users, locate the problematic external account, and delete it completely.
Open your web browser and navigate to your SharePoint site URL. Append exactly '/_layouts/15/people.aspx/membershipGroupId=0' to the end of the address and press Enter.
In the hidden User Information List that appears, find the external user's profile, select it, and choose the option to remove the user from the site collection entirely.
Return to your standard SharePoint site permissions settings and re-invite the external guest account. Instruct the user to open the new invitation in an Incognito/Private window and accept it to trigger a fresh sign-in process.

Frequently Asked Questions
Why am I seeing the SharePoint external user sign-in is not complete error?
This usually happens when the initial guest account provisioning is interrupted, or if the external user attempts to sign into the SharePoint site using a different Microsoft account than the one that was originally invited.
Do I need special permissions to fix this SharePoint sign-in error?
Yes, you must have Microsoft 365 Administrator rights to remove the user from the admin center, and Site Collection Administrator rights to access and edit the hidden SharePoint User Information list.
How do I find the hidden User Information list in SharePoint?
You can access the hidden User Information list by appending '/_layouts/15/people.aspx/membershipGroupId=0' directly to the end of your main SharePoint site URL in the browser's address bar.
