Use the Remove-UMCallAnsweringRule cmdlet to remove an existing Unified Messaging (UM) call answering rule.

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

Remove-UMCallAnsweringRule -Identity <UMCallAnsweringRuleIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Mailbox <MailboxIdParameter>] [-WhatIf [<SwitchParameter>]]

This example removes the call answering rule MyUMCallAnsweringRule from a user's mailbox. The user's mailbox is the mailbox of the user running the cmdlet.

Remove-UMCallAnsweringRule -Identity MyUMCallAnsweringRule

This example removes the call answering rule MyUMCallAnsweringRule from the mailbox of tonysmith.

Remove-UMCallAnsweringRule -Identity MyUMCallAnsweringRule -Mailbox tonysmith

The Remove-UMCallAnsweringRule cmdlet removes an existing UM call answering rule that has been created and stored in a UM-enabled user's mailbox. When you remove an existing call answering rule, all of the remaining call answering rules are still processed in order of their priority.

After this task is completed, the cmdlet sets the parameters and the values specified.

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 "UM call answering rules" entry in the Unified Messaging permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identifier for a call answering rule being removed.




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.




This parameter is available only in on-premises Exchange 2013.

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The Mailbox parameter specifies the UM-enabled mailbox where the call answering rule is changed. The default is the user's mailbox running the cmdlet.
