1 min read

Overview #

This article explains how to create a new user in Microsoft 365 and assign them the Global Administrator role. Global Administrator is the highest-level role and should only be given to trusted individuals as it grants full access to all Microsoft 365 services and settings.

Step 1: Sign in to Microsoft 365 Admin Center #

  1. Go to https://admin.microsoft.com.
  2. Sign in with an existing Global Administrator account.

Step 2: Create the New User #

  1. In the left-hand navigation pane, select Users > Active users.
  2. Click Add a user.
  3. Enter the required details:
  4. Choose the Automatically create a password option (recommended).
  5. Ensure Require this user to change their password when they first sign in is checked.
  6. Click Next.

Step 3: Assign the Global Administrator Role #

  1. On the Assign product licenses page, select a license if required.
  2. Continue to the Optional settings > Roles section.
  3. Select Admin center access.
  4. Choose Global Administrator from the list of roles.
  5. Click Next.

Step 4: Review and Finish #

  1. Review the details you entered.
  2. Click Finish adding.
  3. Copy or download the user’s credentials securely.

Step 5: Test the New Global Administrator Account #

  1. Sign out of the Admin Center.
  2. Log in with the new user’s credentials.
  3. Confirm that the account can access Admin Center and has full admin rights.

Security Best Practices #

  • Limit the number of Global Administrators to two or three maximum.
  • Use Privileged Identity Management (PIM) or enable Multi-Factor Authentication (MFA) on all admin accounts.
  • Do not use Global Admin accounts for day-to-day email or Teams activity.

⚠️ Important: Only assign the Global Administrator role when absolutely necessary. For everyday tasks, consider assigning more restrictive roles such as User Administrator, Exchange Administrator, or SharePoint Administrator.
