SharePoint – Using PowerShell to query the userinfo table

If you are a SharePoint engineer that needs to collect the user's information for a site collection straight from the content database and you don't have access to SQL. You can use a PowerShell script like below to query the content database for your site collection and all its users. It will provide you with the list of users from the site collection's userinfo table along with the authentication format of the user's account. This will help you troubleshoot permissions issues with users that have been added incorrectly or a failed migration.

Note - To run the script, update the site collection in Yellow below with the site collection you are troubleshooting. It will output the data to the screen and to a file called userinfo.txt in the local path.

############################################################################### # This script will return all the users in the Site collection's userinfo table
