Enable-MetaCacheDatabase

This cmdlet is available only in on-premises Exchange.

Use the Enable-MetaCacheDatabase cmdlet to enable the metacache database on Exchange 2019 Mailbox servers. The metacache database stores mailbox database indexes and secondary copies of metadata on solid state drives (SSDs) to improve search latency and user logons.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax (https://docs.microsoft.com/powershell/exchange/exchange-cmdlet-syntax).

Syntax

Description

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

This example enables the metacache database on the Exchange server named Mailbox01.

Parameters

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
