Description

You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't 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

New-MailboxDatabase -Server Server1 -Name "DB1" -EdbFilePath D:\ExchangeDatabases\DB1\DB1.edb

This example creates the mailbox database DB1 on the Mailbox server named Server1. This example also uses a non-default location for the database file.

Parameters

-AutoDagExcludeFromMonitoring

Applicable: Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE

The AutoDagExcludeFromMonitoring parameter specifies that the database being created should not be monitored by managed availability.

Parameter properties

Type:Boolean
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

NonRecovery
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Confirm

Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE

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.
