hi, First you should create a csv file like this: Alias Primaryaddress secondaryaddress Tom @test.com @test1.com tony @just.com @just2.com Then run the cmd in the EMS: Import-Csv Your csv file name | Foreach-Object { $user = Get-Mailbox -Identity $_.Alias $user.EmailAddresses+="$_.Alias$_.Primaryaddress" $user.EmailAddresses+="$_.Alias$_.Secondayaddress" Set-Mailbox $user -EmailAddresses $user.EmailAddresses -EmailAddressPolicyEnabled $false set-mailbox $user -PrimarySMTpAddress "$_.Alias$_.Primaryaddress" -EmailAddressPolicyEnabled $false } hope can help you thanks, CastinLu TechNet Community Support

Castinlu, there are several things wrong with your codeblock. Besides this, it is overkill. As I already stated above, you can add email address policies without a complicated foreach block. e.g. Set-Mailbox tony -EmailAddresses @{Add="tony1@domain.com"} Set-Mailbox tony -EmailAddresses @{Add="tony2@domain.com"} and to set one as primary: Set-Mailbox tony -EmailAddressPolicyEnabled $false -PrimarySmtpAddress tony3@domain.com Mike Crowley | MVP My Blog -- Planet Technologies
