Detailed Description
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"database availability group" entry in the High Availability Permissions topic.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
|
Identity |
Required |
Microsoft.Exchange.Configuration.Tasks.DatabaseAvailabilityGroupIdParameter |
The Identity parameter specifies the name of the DAG from which you are removing the server. |
|
MailboxServer |
Required |
Microsoft.Exchange.Configuration.Tasks.ServerIdParameter |
The MailboxServer parameter specifies the name of the Mailbox server being removed from the DAG. |
|
ConfigurationOnly |
Optional |
System.Management.Automation.SwitchParameter |
The ConfigurationOnly parameter should only be used if the Mailbox server has been lost and can no longer be contacted, or in situations when the Mailbox server will not be restored to operational service before the messaging service is needed. When used, it removes the Mailbox server from the DAG object in Active Directory. If the Mailbox server is offline but the DAG has quorum, the Mailbox server will be evicted from the DAG's cluster and removed from the DAG object in Active Directory. |
|
Confirm |
Optional |
System.Management.Automation.SwitchParameter |
The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch. |
|
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. |
|
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. |

Examples
EXAMPLE 1
This example removes a Mailbox server named MBX1 from a DAG named DAG3.
 Copy Code |
|
|---|---|
Remove-DatabaseAvailabilityGroupServer -Identity DAG3 -MailboxServer MBX1 |
|
EXAMPLE 2
This example removes the configuration settings for Mailbox server named MBX4 from a DAG named DAG2. MBX4 is expected to be offline for an extended period, so its configuration is being removed from the DAG while it is offline in order to establish quorum with the remaining online DAG members.
