Performing Bulk Operations

Bulk Microsoft Entra ID operations refer to the ability to perform a single action or update across multiple users, groups, or other objects in Microsoft Entra ID. This can be especially useful for larger organizations with hundreds or thousands of users, where manual updates to each individual object would be time-consuming and inefficient. Bulk operations in Microsoft Entra ID can be performed using PowerShell, Graph API, or other supported methods. Common bulk operations include adding or removing users from groups, updating user attributes, and managing device settings. We will explore more about the bulk operations you can perform and how they work in the following section.

Some of the popular operations you will learn about in this book perform bulk updates, such as the following:

• Bulk user creation
• Bulk user invitation
• Bulk user deletion
• Bulk user downloads

Performing Bulk Updates Using the Azure Portal

Performing bulk user updates is like managing single users (such as internal and guest users). The only property that can’t be set for multiple users is resetting a password, which must be done for a single user.

Azure has also improved its bulk user settings by adding a drop-down menu that enables you to perform updates via the downloadable CSV template, which you then re-upload.

Downloading a User List

To download a user list, you can follow the given steps:

1. Navigate to the Users overview blade again in Microsoft Entra ID. You should automatically go into the All users blade; if not, select that option.
2. Click Download users from the top menu.

3. Enter a desired filename and click Start. This will be saved as a .csv file, which can be opened in Microsoft Excel if you desire for easy editing. A free version can be used with Microsoft 365 Office online. You can read more about this at this link: https://www.microsoft.com/en-us/microsoft-365/free-office-online-for-the-web. Being a comma-separated file type, where each value is separated by a comma, you can use any text editor, such as Windows Notepad.

4. Once complete, the option to download the file will appear. Click the blue text to download.

When opening the file, if you are presented with what looks like gibberish, you can do the following in Excel to format it neatly for yourself:

1. Click the A column to select all the data:

2. Then, select the Data tab from the top menu bar, and then select Text to Columns from the Data Tools context.

3. On the screen that pops up, click Delimited and then Next.

4. Select Comma, and then click Next >.

5. Click General for Column data format, and then click Finish.

Now, your data will be organized neatly into columns. Next, you will learn how to use this sheet to perform bulk deletion operations in Microsoft Entra ID.

Bulk User Deletion Operations

To demonstrate a bulk deletion, you will select and keep the users you want to retain in the sheet and delete the rows with the remaining users:

1. Navigate back to the Users blade and select All users.
2. Click Bulk operations and then Bulk delete.

3. Click Download.

4. Modify the sheet and paste in the user principal name for each user, from row 3 downward. You can copy these users from the sheet you downloaded in the last exercise. Click Save once you are finished and close the Excel sheet.

5. Back in the Azure portal, click the Select a file option from the previous screen. From the open file dialog that pops up, navigate to your file, and then click Open.
6. In the Azure portal, select Yes for the Are you sure you want to perform the delete operation? option, and then click Submit. You will be presented with a success notification once completed successfully.
7. That concludes the bulk user delete operation demonstration. Next, you will briefly explore other possible ways to modify Microsoft Entra ID user accounts.

Updating Multiple Users

You can also update multiple users by selecting them and choosing to delete them, or you can configure MFA for each user from the Azure portal in the Users blade:

This concludes our demonstration of how to perform bulk user deletion operations using the Azure portal. Next, we will take a look at a PowerShell script that I think can help you achieve bulk user creation.

Performing Bulk Creations Using PowerShell

You will now experience running a PowerShell script to enable you to create Microsoft Entra ID users quickly and programmatically in your environment. The following script will create several demo users with a predefined password for you:

1. Start by opening your favorite code editor or notepad; I recommend VS Code, which you can download from here: https://code.visualstudio.com/download.
2. Paste the following code and save the file as a .ps1 file, with whatever name prefix you want. To follow this exercise, it is advised that you save the file in C:\Scripts on your computer and name it Create_AzureAD_Users.ps1. You will need to populate the $TenantId and $DomainSuffix details in between the inverted commas on the right.

Create_AzureAD_Users.ps1

# Enter the Tenant ID for your Azure AD
$TenantId = ""
# Populate your Domain Suffix
$DomainSuffix = ""
# List of usernames to create
$UserNames = @(
    "John Smith",
    "Jane Doe",
    "Robert Johnson",

The complete code is available at https://packt.link/CEwga

3. Note the location of your script (e.g., C:\Scripts), and then open PowerShell.
4. Type in cd and the path to your script, and then press the Enter key.

5. Now, to run the script, enter .\ and start typing your script name. The .\ notation means that you will look in the path that you are currently in – in my example, C:\Scripts. Click Enter once you have your script.

6. A prompt will pop up, asking you to authenticate; enter your details and sign in.

7. Return to the Azure portal and navigate to Microsoft Entra ID, and then the Users blade. You should see your new users there.

This concludes our demonstration on how to perform bulk user creations using a PowerShell script, helping you to achieve a consistent deployment methodology that can also save you time.
