Manage Microsoft 365 Users Using Bulk Operations

Managing users in Microsoft 365 can become time-consuming and error-prone—especially when you're handling dozens or hundreds of accounts. That’s where bulk operations with PowerShell come in. With just a few lines of script, you can create, modify, or even delete user accounts efficiently.

This guide introduces you to bulk operations for user management and provides helpful resources to get started—using trusted, real-world examples from M365Corner.

What are Bulk Operations?

Bulk operations refer to performing a specific task—such as user creation, license assignment, or password reset—for multiple users at once, instead of handling each user individually.

These operations are typically driven by PowerShell scripts and are especially useful in large organizations where manual handling is impractical.

Bulk operations are valuable for IT administrators because they:

• Save Time: Handle hundreds of user accounts in seconds.
• Ensure Accuracy: Avoid repetitive errors due to manual inputs.
• Support Automation: Easily integrate with onboarding and offboarding processes.
• Improve Efficiency: Respond quickly to changes like department shifts or compliance needs.
• Enable Scaling: Perfect for growing organizations managing users across departments and regions.
