Module:
Exchange PowerShell

This cmdlet is available only in the cloud-based service.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Syntax

Default (Default) 

Remove-MailboxIRMAccess
    [-Identity] <MailboxIdParameter>
    -User <SecurityPrincipalIdParameter>
    [<CommonParameters>]

Description

Note

This cmdlet works only for delegates who already have Full Access permission to the mailbox. For more information, see Manage permissions for recipients in Exchange Online.

You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Remove-MailboxIRMAccess -Identity lynette@contoso.onmicrosoft.com -User chris@contoso.onmicrosoft.com

This example removes the restriction from IRM-protected messages in Lynette's mailbox for delegate Chris. In other words, delegate Chris can now access IRM-protected messages in Lynette's mailbox.
