How do I remove user access to Mailbox


In this article you will learn how to remove User Access to Mailbox using PowerShell and CoreView.

Using PowerShell:

Use the Remove-MailboxPermission cmdlet to remove permissions from a user's mailbox or from an Exchange Server 2016, Exchange Server 2019 or Exchange Online mail user. 

The Remove-MailboxPermission cmdlet allows you to remove permissions from a user's mailbox, for example, removing full access to another user's mailbox.

You need to be assigned permissions before you can run this cmdlet.

To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.




Remove-MailboxPermission -Identity "CoreView Demo" -User "Test User" -AccessRights FullAccess -InheritanceType All

This example removes Test User's full access permission to  CoreView Demo mailbox.
