A situation where an Office 365 admin left the company

Handling a situation where an Office 365 admin has left the company without transferring admin rights can be critical, as it can prevent the organization from managing its Office 365 tenant and users. Fortunately, Microsoft provides a few options to regain control of the Office 365 admin account. Here's a detailed step-by-step process to help you regain access and transfer the admin rights.

Step 1: Check If Another Admin Account Exists

  1. Log In to Office 365: First, check if another person within the organization has administrative privileges in Office 365. You can check the admin roles by following these steps:

    • Go to the Microsoft 365 Admin Center (admin.microsoft.com).
    • Under the Users section, select Active users.
    • In the user list, check if there are any other Global Admin users. If yes, they can assign admin rights to another user or recover the account.

  2. Use Another Admin Account: If you find an active admin account:

    • Log in with the Global Admin credentials.
    • Assign a new admin account or restore the Global Admin role to a designated user.

If no other Global Admin exists, follow the steps below to recover the account.

Step 2: Try to Recover the Global Admin Account

If no admin rights exist, and the original admin has left, you will need to initiate the global admin account recovery. Here’s what you can do:

A. Use the “Global Administrator” Account Recovery Process

  1. Visit Microsoft’s Account Recovery Portal:

  2. Sign In to the Microsoft 365 Admin Center:

    • Use the email and password of the Global Admin account that was used by the previous administrator (if known). If you don’t have the credentials, you may need to use the admin recovery process.

  3. Account Recovery:

    • If you are unable to sign in, use the Forgot Password link on the Microsoft 365 sign-in page. Microsoft will ask you to verify your identity using any recovery methods set up, such as email, phone, or authentication app.

  4. Verify Identity:

    • If you're the designated recovery contact, provide the necessary details, such as the organization name, the user’s last known email, or other information about the account to help verify your identity.

  5. Reset Password:

    • Once identity verification is successful, you can reset the password and gain access to the admin account.

B. Utilize Microsoft’s Support for Admin Recovery

If you still cannot access the Global Admin account, Microsoft offers support to help you recover admin rights.

  1. Contact Microsoft Support:

    • Visit Microsoft Support at https://support.microsoft.com.
    • Choose Contact Support.
    • Select Office 365 or Microsoft 365.
    • Choose the appropriate option for admin recovery.

  2. Verify Ownership of the Organization:

    • Microsoft may ask you to provide proof of ownership of the domain or organization. This could include verifying your organization’s domain (e.g., through the domain registrar) or providing identification of the authorized owner.

  3. Provide Support Information:

    • You may need to prove that you are an authorized user of the organization (e.g., through identity verification or organization information) to complete the recovery process.

  4. Regain Access:

    • After a successful verification, Microsoft support will guide you through the process of gaining access to the Global Admin account or transferring the rights to another admin account.

Step 3: Assign New Global Admin Rights

Once you have recovered access to the Global Admin account, you should assign new admin rights to one or more users to ensure this situation does not repeat. Here’s how to do that:

  1. Login to Microsoft 365 Admin Center:

  2. Assign Global Admin Rights:

    • Go to Users > Active Users.
    • Find the user who will be given admin rights, click on their name to open their user details.
    • Under the Roles section, click Manage roles.
    • Select Global Administrator and save the changes.

  3. Verify New Admin Rights:

    • Log out and ask the new admin to log in and verify their admin rights have been applied successfully.

Step 4: Change Security Information and Recovery Options

To prevent similar situations in the future, it’s a good idea to change security settings and recovery options for the Global Admin account:

  1. Update Security Information:

    • In the Microsoft 365 Admin Center, navigate to Security & Privacy.
    • Ensure that your Global Admin account has up-to-date security information, such as a backup phone number, alternate email, and multi-factor authentication options.

  2. Enable Multi-Factor Authentication (MFA):

    • Go to Users > Active Users.
    • Select the user who is the Global Admin and enable Multi-Factor Authentication (MFA) to add an extra layer of security.

Step 5: Assign Additional Admin Roles (Optional)

It’s a good practice to assign additional admin roles to ensure that there is a backup in case another admin leaves unexpectedly:

  1. Assign Other Admin Roles:
    • You can assign roles such as Billing Administrator, User Management Administrator, or Compliance Administrator to other trusted users in the organization. These roles will allow different users to manage certain aspects of Office 365 without needing full Global Admin access.
  2. Create a Backup Admin:
    • Designate at least one backup admin who will be available to handle admin tasks if the primary admin leaves again. Make sure to document the recovery process and who holds the backup admin credentials.

Step 6: Audit the Global Admin Account Regularly

Once the admin rights are recovered, it’s important to perform regular audits of the admin accounts to ensure there are no issues in the future:

  1. Review Active Admin Accounts:
    • In the Microsoft 365 Admin Center, go to Users > Active Users and filter for users with admin roles.
    • Regularly review and ensure that only trusted users have Global Admin or other elevated privileges.
  2. Monitor Account Activity:
    • Use Azure AD Sign-ins or Audit Logs to monitor activity from admin accounts. Any unauthorized changes or login attempts should be flagged and investigated.

Conclusion

When an Office 365 admin leaves the company without transferring admin rights, it can pose significant risks, such as being unable to manage the Office 365 environment. However, by following these steps, you can regain access to the Global Admin account either through account recovery, Microsoft support, or by using backup admin accounts. Additionally, implementing security measures like multi-factor authentication (MFA) and assigning multiple admin roles can help prevent similar issues in the future.

By taking these proactive steps, you ensure the organization remains in control of its Office 365 environment and is better prepared for administrative challenges down the road.
