Enable automatically update email addresses based on email address policy
Before you enable the setting in Exchange Admin Center for the user, it’s good to know which options there are. For example, you can enable it for:
- A specific mailbox
- Mailboxes in an Organizational Unit
- Mailboxes in a text file
- Mailboxes in a CSV file
- All mailboxes (user mailboxes, resource mailboxes, and shared mailboxes)
Enable setting for a specific mailbox
Before you start, run Exchange Management Shell as administrator.
Run the Get-Mailbox cmdlet and check if the object EmailAddressPolicyEnabled shows the True or False value for the specific mailbox.
The policy option is not enabled for the user mailbox because it’s showing as False.
[PS] C:\>Get-Mailbox -Identity "Amanda.Morgan@exoip.com" | ft Name, EmailAddressPolicyEnabled
Name EmailAddressPolicyEnabled
---- -------------------------
Amanda Morgan False
Enable the email address policy option for the specific mailbox.
[PS] C:\>Get-Mailbox -Identity "Amanda.Morgan@exoip.com" | Set-Mailbox -EmailAddressPolicyEnabled $True
Enable setting for mailboxes in an Organizational Unit
Run the Get-Mailbox cmdlet and check if the object EmailAddressPolicyEnabled shows the True or False value for the mailboxes in an Organizational Unit.
Some mailboxes have the value False, and other mailboxes show the value as True.
[PS] C:\>Get-Mailbox -OrganizationalUnit "exoip.local/Company/Users/IT" | ft Name, EmailAddressPolicyEnabled
Name EmailAddressPolicyEnabled
---- -------------------------
Jake Cornish False
Julian Walsh True
James Paterson False
Piers Rees False
Jeff Allan True
List only the mailboxes that don’t have the setting enabled in the Organizational Unit.
[PS] C:\>Get-Mailbox -OrganizationalUnit "exoip.local/Company/Users/IT" | Where-Object {$_.EmailAddressPolicyEnabled -eq $False} | ft Name, EmailAddressPolicyEnabled
Name EmailAddressPolicyEnabled
---- -------------------------
Jake Cornish False
James Paterson False
Piers Rees False
Enable the email address policy setting for the mailboxes in the Organizational Unit that doesn’t have the setting enabled.
[PS] C:\>Get-Mailbox -OrganizationalUnit "exoip.local/Company/Users/IT" | Where-Object {$_.EmailAddressPolicyEnabled -eq $False} | Set-Mailbox -EmailAddressPolicyEnabled $True
Enable setting for mailboxes in a text file
Create a text file with the name users.txt in C:\temp. Put the names of the mailboxes or the email addresses in the text file. Read more on how to export a list of mailboxes to text file.
With the Get-Content cmdlet, you can read the information in the text file.
[PS] C:\>Get-Content "C:\temp\users.txt" | Get-Mailbox | Where-Object {$_.EmailAddressPolicyEnabled -eq $False} | ft Name, EmailAddressPolicyEnabled
Name EmailAddressPolicyEnabled
---- -------------------------
Amanda Morgan False
Benetiz Anees False
Enable the email address policy setting for the mailboxes in the text file that don’t have the setting enabled.
[PS] C:\>Get-Content "C:\temp\users.txt" | Get-Mailbox | Where-Object {$_.EmailAddressPolicyEnabled -eq $False} | Set-Mailbox -EmailAddressPolicyEnabled $True
Enable setting for mailboxes in a CSV file
If you followed the article List users not inheriting email address policy, you already have the CSV file exported. Place the NotInherting.csv file in C:\temp.

Ali, your articles are best, I wish you were writing directly for Microsoft. I do have a question on email address updates. We have a default company wide policy and then a second policy of higher rating for a subset of users to get a different domain. If a user already has the default applied and their criteria changes that the higher policy should take affect it doesnt automatically. If I uncheck the automatically apply on the user and save and the recheck and save again the second policy is applied. I would think it should auto apply on its own.
