Detailed Description

The Update-EmailAddressPolicy cmdlet queries for all recipients that match the specified email address policy and saves the objects to Active Directory. Use the Update-EmailAddressPolicy cmdlet after you use the Set-EmailAddressPolicy cmdlet to apply all changes. For more information about the Set-EmailAddressPolicy cmdlet, see Set-EmailAddressPolicy.

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 "Email address policies" entry in the Email Address and Address Book Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the GUID, distinguished name (DN), or email address policy name that represents a specific email address policy. You can also include the path by using the format Path\EmailAddressPolicy.

You can omit the parameter label Identity so that only the email address policy name or GUID is supplied.




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.




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




The FixMissingAlias switch repairs recipients that don't have an alias. The alias is generated based on the name of the recipient. You need to use the FixMissingAlias parameter if you receive an error message when you attempt to update an email address policy, global address list, or address list.




The UpdateSecondaryAddressesOnly switch parameter specifies to update the secondary email addresses only. If you specify this parameter, the primary proxy email address isn't updated.




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.
