| Parameter | Required | Type | Description |
|---|---|---|---|
|
AccessRights |
Required |
Microsoft.Exchange.Management.RecipientTasks.MailboxRights[] |
The AccessRights parameter specifies the rights needed to perform the operation. Valid values include:
|
|
Identity |
Required |
Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter |
The Identity parameter specifies the identity of the mailbox that's getting permissions added. You can use the following values:
|
|
Instance |
Required |
Microsoft.Exchange.Management.RecipientTasks.MailboxAcePresentationObject |
The Instance parameter is no longer used and will be deprecated. |
|
Owner |
Required |
Microsoft.Exchange.Configuration.Tasks.SecurityPrincipalIdParameter |
The Owner parameter specifies the owner of the mailbox object. |
|
User |
Required |
Microsoft.Exchange.Configuration.Tasks.SecurityPrincipalIdParameter |
The User parameter specifies the user mailbox that the permissions are being granted to on the other mailbox. |
|
Confirm |
Optional |
System.Management.Automation.SwitchParameter |
The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax |
|
Deny |
Optional |
System.Management.Automation.SwitchParameter |
The Deny switch specifies whether to deny permissions to the user on the mailbox. |
|
DomainController |
Optional |
Microsoft.Exchange.Data.Fqdn |
The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory. |
|
IgnoreDefaultScope |
Optional |
System.Management.Automation.SwitchParameter |
The IgnoreDefaultScope parameter instructs the command to ignore the default recipient scope setting for the Exchange Management Shell session and use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently in the default scope. Using the IgnoreDefaultScope parameter introduces the following restrictions:
|
|
InheritanceType |
Optional |
System.DirectoryServices.ActiveDirectorySecurityInheritance |
The InheritanceType parameter specifies whether permissions are inherited by folders within the mailbox. |
|
WhatIf |
Optional |
System.Management.Automation.SwitchParameter |
The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch. |
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Permissions and delegation" entry in the Mailbox Permissions topic.
