Deletes registered session configurations from the computer.
The Unregister-PSSessionConfiguration cmdlet deletes registered session configurations from the computer. This is an advanced cmdlet that is designed to be used by system administrators to manage customized session configurations for their users.

If you accidentally delete the default Microsoft.PowerShell or Microsoft.PowerShell32 session configurations, use the Enable-PSRemoting cmdlet to restore them.

Unregister-PSSessionConfiguration [-Name] <string> [-Force] [-NoServiceRestart] [-Confirm] [-WhatIf] [<CommonParameters>]

Use the Uninstall-TransportAgent cmdlet to unregister a transport agent that is no longer needed on a computer that has the Edge Transport server role or the Hub Transport server role installed in a Microsoft Exchange Server 2007 organization.
The Uninstall-TransportAgent cmdlet is used to unregister a transport agent that is no longer needed on an Edge Transport server or a Hub Transport server.
To run the Uninstall-TransportAgent cmdlet, the account you use must be delegated the following:
* Exchange Server Administrator role and local Administrators group for the target server
To run the Uninstall-TransportAgent cmdlet on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.
Uninstall-TransportAgent -Identity <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]

Cancels an event subscription.
The Unregister-Event cmdlet cancels an event subscription that was created by using the Register-EngineEvent, Register-ObjectEvent, or Register-WmiEvent cmdlet.

When an event subscription is canceled, the event subscriber is deleted from the session and the subscribed events are no longer added to the event queue. When you cancel a subscription to an event created by using the New-Event cmdlet, the new event is also deleted from the session.

Unregister-Event does not delete events from the event queue. To delete events, use the Remove-Event cmdlet.

Unregister-Event [-SubscriptionId] <int> [-Force] [-Confirm] [-WhatIf] [<CommonParameters>]

Unregister-Event [-SourceIdentifier] <string> [-Force] [-Confirm] [-WhatIf] [<CommonParameters>]

The Update-List cmdlet adds items to and removes items from a property value of an object, and then it returns the updated object. This cmdlet is designed for properties that contain collections of objects.

The Add and Remove parameters add individual items to and remove them from the collection. The Replace parameter replaces the entire collection.

If you do not specify a property in the command, Update-List returns an object that describes the update instead of updating the object. You can submit the update object to cmdlets that change objects, such as Set-* cmdlets.

This cmdlet works only when the property that is being updated supports the IList interface that Update-List uses. Also, any Set-* cmdlets that accept an update must support the IList interface. The core cmdlets that are installed with Windows PowerShell do not support this interface. To determine whether a cmdlet supports Update-List, see the cmdlet Help topic.

Update-List [-Add <Object[]>] [-Remove <Object[]>] [[-Property] <string>] [-InputObject <psobject>] [<CommonParameters>]

Update-List -Replace <Object[]> [[-Property] <string>] [-InputObject <psobject>] [<CommonParameters>]

Use the Update-FileDistributionService cmdlet to use the File Distribution Service to poll for offline address book (OAB) and Unified Messaging (UM) configuration and data.
This cmdlet will force the File Distribution Service to reload its configuration and poll for new data associated with OAB and UM configuration.
To run the Update-FileDistributionService cmdlet, the account you use must be delegated the following:
* Exchange Server Administrator role and local Administrators group for the target server

Update-FileDistributionService -Identity <ServerIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Type <String>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]

Use the Update-OfflineAddressBook cmdlet to update the offline address books (OABs) that are used by Microsoft Outlook clients.
This cmdlet allows administrators to update OABs.
To run the Update-OfflineAddressBook cmdlet, the account you use must be delegated the following:
* Exchange Server Administrator role and local Administrators group for the target server.
Update-OfflineAddressBook -Identity <OfflineAddressBookIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]

Use the Update-Recipient cmdlet to add Microsoft Exchange Server 2007 attributes to recipient objects that are created by the global address list (GAL) synchronization management agent in Identity Lifecycle Manager (ILM) 2007. The recipient objects you modify using this cmdlet must reside on an Exchange 2007 server.
Due to mergers and acquisitions or legal requirements, customers may have a need to deploy Exchange in a multiple Exchange forest topology. These deployments require the synchronization of recipient objects across disparate Active Directory directory service forests. To learn more about multiple Exchange forest topologies, see Planning for a Complex Exchange Organization.
Microsoft provides the GAL synchronization management agent for synchronizing recipient objects. The version of the GAL synchronization management agent that was included in Microsoft Identity Integration Server (MIIS) 2003 was designed to work with Exchange Server 2003 and relied on the Recipient Update Service (RUS). Because RUS is a deprecated feature and is no longer required for Exchange 2007, the new GAL synchronization management agent that is included in ILM 2007 is designed to function without RUS
As part of the synchronization process, the ILM 2007 GAL synchronization management agent creates recipient objects in both Active Directory forests. After the recipients are created, the management agent uses the Update-Recipient cmdlet to add the attributes required by Exchange 2007 to complete the provisioning of these recipients.
If you are using MIIS 2003, you must run various cmdlets to complete the provisioning process of the mail contacts created by the GAL synchronization management agent. For detailed information about provisioning mail contacts created by MIIS 2003, see How to Deploy Exchange 2007 in a Cross-Forest Topology. The Update-Recipient cmdlet provides an alternative and more efficient method to accomplish this. You can simply run the Update-Recipient cmdlet against the recipient objects created by the MIIS 2003 GAL synchronization management agent to complete their provisioning process.
To run the Update-Recipient cmdlet, the account you use must be delegated the following:
* Exchange Recipient Administrator role
Update-Recipient -Identity <RecipientIdParameter> [-Confirm [<SwitchParameter>]] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]

To use the Update-PublicFolder cmdlet, the account you use must be delegated the following:
* Exchange Public Folder Administrator role and local Administrators group for the target server.
Update-PublicFolder -Identity <PublicFolderIdParameter> -Server <ServerIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]

To use the Update-PublicFolderHierarchy cmdlet, the account you use must be delegated the following:
* Exchange Public Folder Administrator role and local Administrators group for the target server.

Update-PublicFolderHierarchy -Server <ServerIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]] [<CommonParameters>]
