SharePoint Online: Permission Report for Specific User in a Site Collection using PowerShell

Requirement:  Generate a permission report to audit a specific user's permissions in given SharePoint Online site collection, sub-sites, all its lists, libraries and list items.

How to Check User Permissions in SharePoint Online?
To get user permissions in SharePoint Online,
  • Navigate to the SharePoint Online site on which you want to check permissions.
  • Click on Settings Gear >> Site Settings >> Click on "Site Permissions" link.
  • On the Site permissions page, under Permissions tab, click "Check Permissions" icon in the top ribbon.
  • In the User/Group field, Enter the User Name which you want to verify permissions, and click on "Check Now" button
  • In a moment, You will see list of permissions the user has on a site.

But the problem is: This method of checking user permissions shows access to one site at a time. You should repeat these steps in each site, if you want to check user access for a site collection. So lets use PowerShell to generate user permissions report for SharePoint Online.

Here is how to check user permissions using PowerShell in SharePoint Online. Please note, there is a limitation in the script: This PowerShell script doesn't scan Active Directory security groups!

  1. awesome script !!! thank you.

  2. wonderfull.. you saved my day..

    Adding one more If condition to full Security groups is working absolutely fine.
    $RoleAssignment.Member.PrincipalType -eq "SecurityGroup"

  3. Hi Salaudeen,

    Thanks for your script.

    As the result, it only shows the site permission information not including library and folder. Is it possible you can help to list the library permission with users and groups?

    Appreciate it if you can help.

  4. Script working for small lists. Having problems with large lists. I am new to PowerShell. Can you please update the script to use linq to resolve performance issues?

  5. Absolutamente bueno. Solo tengo un problema y es la conexion con el office 365

    1. Reducing the Row Limit from 2000 to 500 resolves the problem: Exception calling "ExecuteQuery" with "0" argument(s): "The underlying connection was closed: An unexpected error occurred on a receive."

    2. Hi Salaudeen, I'm getting the below error
      "Error Generating User Permission Report! Exception calling "ExecuteQuery" with "0" argument(s): "The underlying connection was closed:
      An unexpected error occurred on a send."

      Please provide your comments and also how to change the row limit as mentioned above

    3. In Line#9, set the $BatchSize to 100 from 500. Also, run the PowerShell console as "Administrator".

  6. Hi..

    $RoleAssignment.Member.Users is available???. Seems to be not working..

  7. Hi Salaudeen, I'm getting the error as mentioned above.. can you please let me know where to change the row limit?

    1. Thanks for your reply. But it's not working. I guess csom related scripts we can't run in our environment. So do you have any other scripts which can pull the permission of a user in online sharepoint?

    2. Can you elaborate the problem please? CSOM-PowerShell scripts can be run on any desktops with CSOM SDK installed.
