If your Office 365 users are in the cloud, you can easily delete them via the admin center.

Take a look at the video demo above, or follow these steps:

1. From the admin center, go to Users, and select Active Users.
2. Select the name of the user you wish to delete, and click DELETE.
3. Click Yes when the confirmation box appears.

Things to note:

• If you’re using directory synchronization, you have to delete your users from the local Active Directory.
• When an account is deleted, it goes into a 30-day holding period until “hard delete.” Information can be retrieved within that period.
• If an employee leaves the company, deleting their user profile should be part of an overall Office 365 deprovisioning process.
