The people on your team each need a user account before they can sign in and access Office 365 for business. The easiest way to add user accounts is to add them one at a time in the Microsoft 365 admin center. After you do this step, your users will have Office 365 licenses, sign in credentials, and Office 365 mailboxes.

After you add a user, you'll get an email notification from the Microsoft Online Services Team. The email will contain the person's Office 365 user ID and password so they can sign in to Office 365. You need to tell your new user about their Office 365 sign in information. Use your normal process for communicating new passwords.


If you create users by migrating mail boxes, you will need to activate Office 365 user accounts by assigning licenses. If you don't assign a license to a user, their mailbox will be disabled after a grace period of 30 days. See how to assign licenses to users using the Microsoft 365 admin center.

Have hundreds or thousands of users to add?

To add multiple users at the same time, follow these steps:

  • Use a spreadsheet to add people in bulk. See Add several users at the same time.

  • Automate adding accounts and assigning licenses. See Create user accounts with Office 365 PowerShell. Choose this method if you're already familiar with using Windows PowerShell cmdlets.

  • Using ActiveDirectory? Set up directory synchronization for Office 365. Use the Azure AD Connect tool to replicate Active Directory user accounts (and other Active Directory objects) in Office 365. The sync only adds the user accounts. You will need to assign licenses to the synced users before they can use email and other Office apps.

  • Migrating from Exchange? Ways to migrate multiple email accounts to Office 365. When you migrate multiple mailboxes to Office 365 by using either cutover, staged, or a hybrid Exchange method, you will add users automatically as part of the migration. The migration only adds the user accounts. You will need assign licenses to the users before they can use email and other Office apps.
