Syntax

Set-MailboxIRMAccess
   -AccessLevel <IRMAccessLevel>
   [-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 topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not 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

Set-MailboxIRMAccess -Identity lynette@contoso.onmicrosoft.com -User chris@contoso.onmicrosoft.com -AccessLevel Block

This example prevents delegate Chris from reading IRM-protected messages in Lynette's mailbox.

Parameters

-AccessLevel

The AccessLevel parameter specifies what delegates can do to IRM-protected messages in the mailbox that's specified by the Identity parameter.

The only value for this parameter is Block, which means you can only use this cmdlet to block delegate access to IRM-protected messages in the mailbox.

To allow access to IRM-protected messages in the mailbox, use the Remove-MailboxIRMAccess cmdlet.
