Add Users in Bulk to SharePoint Groups

The other day I had a user ask to add 600+ users to a SharePoint group. Immediately I knew PowerShell was going to save the day, again. So, here is the script I wrote. You can download the full script along with a sample answer file. All I ask is that you let me know if you run into issues, and know that this script is provided as-is with no warranty or guarantees. I haven’t taken into account all possible errors so my error handling is very limited here.

**Typically it is recommended you use an Active Directory security group, but sometimes we have to make exceptions**

Don’t freak out because of the amount of code. Most of the code is building the menu to make it easy for even the least experienced PowerShell user to use. I write a lot of PowerShell scripts, so I don’t like having to open a script and review it to determine what/how to run it. Yes, I could build a help menu for the script, but I prefer a menu that will simply give me and others on my team the options to choose from. The screenshots below should help you understand what the code is doing. The help menu will bring you to this article.


  • Run the file named Add-SPUser_Group.ps1 from the SharePoint CLI
  • Enter a path to a directory to store the activity log (see below)



  • Enter A at the menu (see below)



  • Enter the path and filename of the .csv answer file (example answer file included in script download)
  • Enter the URL of the site to add the users to
  • Enter the Group ID

You can find the Group ID of a SharePoint Group by navigating to the Group in the browser. The ID is in the URL of the group



  • The list of Usernames will be displayed to you (Usernames must be in DOMAIN\Username format in your answer file) (see below)



  • You will see one of the following messages for each user in your answer file
    • “DOMAIN\Username” created and added to “Group ID” (displayed if a user account did not exist in the site. The account is added to the site, then added to the group)
    • “DOMAIN\Username” has been added to “Group ID” (displayed if a user already exists in the site and is added to the group)


  • You will now be brought back to the main menu shown in STEP 2

  1. Hello,

    Just tried this and it works great.

    I do have a question.

    How can I make this that it works for external users? I see that this script reads users from the AD, but what if I want to add external users?

    Appreciate your time and help.
