Different Ways to Manage Microsoft 365 Users

Microsoft provides two primary ways to manage user accounts:

1. Using Microsoft 365 Admin Center

The Admin Center is best suited for manual tasks or when working with a few users. Here's a breakdown of what you can do:

👁️ Viewing Users

• Go to Users > Active users to view the complete list of users.
• See their sign-in status, assigned licenses, roles, and last activity.

➕ Creating Users

• Navigate to Users > Active users > Add a user.
• Enter name, username, location, password settings, and assign licenses.
• Optional: Force password change on first login.

📥 Creating Multiple Users (Bulk Import)

• Select Add multiple users > Download the CSV template.
• Fill in required fields (e.g., Display Name, Username, Location).
• Upload the filled CSV and complete the import process.
• Admin Center validates entries and highlights any errors for correction.

📝 Updating Users

• Select a user from the list and update the required info.
• Common updates include job titles, department, and location.

❌ Deleting Users

• Select a user > click Delete user.
• Deleted users can be restored within 30 days via the Deleted users tab.
2. Using Microsoft Graph PowerShell

For automation, bulk operations, and enterprise-level management, PowerShell is a powerful alternative. With a few cmdlets, you can manage thousands of users programmatically.

Here are the key cmdlets for user management:

• Get-MgUser – View user details and status
• New-MgUser– Create a new Microsoft 365 user
• Update-MgUser– Modify user properties
• Bulk Update Microsoft 365 User Attributes Using Update-MgUser
• Remove-MgUser – Delete a user account
• Bulk Remove Microsoft 365 Users Using Remove-MgUser

Conclusion

The Microsoft 365 Admin Center offers an approachable and powerful way to manage your organization’s users. It's perfect for day-to-day tasks, quick edits, and visual monitoring. However, as your environment grows, adopting Microsoft Graph PowerShell unlocks deeper control, speed, and automation.
