Hi , I'm trying to bulk mail enable a group of users belonging to several OU but I'm having problem with Exchange management shell The command I'm trying to use is get-user | enable-mailuser . My problem is that I did not find a way to pass the external amil address I want to assign to each user . I wish to create an external address in the form InitialFirstName.Lastname@domain.com I've tried the following get-user -OrganizationalUnit "TESTEXCH" -recipienttypedetails user | enable-MailUser -ExternalEmailAddress smtp_.FirstName@domain.com but it fails . Essentially I failed to find a way to pass the $_ variabile ( or someting similar ) as the left part of the -externalEmail address Can Anyone help me ? Thanks

You might want to try creating an array of users: $users = Get-User -OrganizationalUnit "TESTEXCH" -RecipientTypeDetails user Then run a foreach to generate an email variable and mail-enable the user: ForEach($u in $users) { $mail = "SMTP:" $mail += $u.FirstName #(or $u.givenName) $mail += "@domain.com" Enable-MailUser $u -ExternalEmailAddress $mail }

For Initial First Name & Last Name in external SMTP address, you can edit the below line into Jim's code. $mail += $u.FirstName.substring(0,1) #(or $u.givenName.substring(0,1)) $mail += "." $mail += $u.LastName

thanks to all for the help , it worked fine
