Reset-ProvisioningCache

 

Applies to: Exchange Server 2013

Topic Last Modified: 2014-03-05

This cmdlet is available only in on-premises Exchange Server 2013.

The Reset-ProvisioningCache cmdlet clears the Windows PowerShell provisioning cache of frequently used Active Directory objects. This cmdlet is only used for diagnostic purposes.

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

Reset-ProvisioningCache -Application <String> -GlobalCache <SwitchParameter> -Server <Fqdn> <COMMON PARAMETERS>
Reset-ProvisioningCache -Application <String> -Server <Fqdn> [-CurrentOrganization <SwitchParameter>] [-Organizations <MultiValuedProperty>] <COMMON PARAMETERS>
COMMON PARAMETERS: [-CacheKeys <MultiValuedProperty>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

This example resets the provisioning cache for Windows PowerShell running on the server EXSRV1.contoso.com in an on-premises Exchange organization and specifies that all cache keys are cleared.

Reset-ProvisioningCache -Server EXSRV1.contoso.com -Application Powershell -GlobalCache

This example runs in a multi-tenant deployment by a data center administrator to reset the provisioning cache for Windows PowerShell for the adatum.com tenant and clear all cache keys.

Reset-ProvisioningCache -Application Powershell-Proxy -Server datacenter1.adatum.com -GlobalCache

The Reset-ProvisioningCache cmdlet is for diagnostic purposes only and is rarely used. Exchange administrators need to run this cmdlet only if incorrect links or properties are stamped on newly provisioned recipients, which can be caused by stale data in the provisioning cache. This is a rare occurrence because the provisioning cache has invalidation notification logic.

The Reset-ProvisioningCache cmdlet clears the Windows PowerShell provisioning cache of frequently used Active Directory objects. To reduce Active Directory requests, a provisioning cache is initialized in each Windows PowerShell runspace and is used to cache common objects that are frequently used by cmdlets and provisioning handlers. During Exchange cmdlet execution, the provisioning cache loads configuration objects from Active Directory to help run a cmdlet. For example, when you create a mailbox, the New-Mailbox cmdlet obtains properties from Active Directory. When running cmdlets, configuration objects such as database containers, administrative role groups, and LegacyDNs are retrieved from Active Directory. Because these types of objects are stable and don't change for months or years after they're created, they're stored in the provisioning cache used by Windows PowerShell. This increases provisioning efficiency and significantly improves cmdlet performance.

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 "Exchange server configuration settings" entry in the Exchange and Shell infrastructure permissions topic.

CacheKeys

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The CacheKeys parameter specifies the value for the cache key that you want to clear. The format for the values should contain 32 digits separated by four dashes: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Use the Dump-ProvisioningCache cmdlet to return a list of cache keys.

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 -Confirm:$False. You must include a colon ( : ) in the syntax.

CurrentOrganization

The Organizations parameter specifies the organizations that the provisioning cache will be reset. This parameter is used in multi-tenant deployments.

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.
