My company has recently split into about 5 separate groups of companies all with different domains. I have updated each Exchange 2007 mailbox with the correct reply to email address, but when I look into my AD the email address that is showing in the General Tab is still the old email address of course.Does anyone know a way to update my AD with the default reply to address?I apologize if this is a newbie question, but I'm still learning.Thanks in advance for any direction you could provide.

If the reply to addresses are correct, open ems and type..get-mailbox | export-csv c:\user.csvopen the csv in excel, verify that the primarysmtpaddress column is correct, then..import-csv c:\users.csv | foreach {set-mailbox -identity $_.alias -WindowsEmailAddress $_.PrimarySmtpAddress}

Thanks LKeneston...The export worked perfectly, but when I run the import, I recieve:cmdlet set-mailbox at command pipeline position 1Supply values for the following parameters:Identity:Any ideas?Thanks for the help and quick responce!

My mistake..import-csv c:\users.csv | foreach {set-mailbox -identity $_.alias -WindowsEmailAddress $_.PrimarySmtpAddress}

LKeneston - Thanks so much for your assistance...That worked flawlessly!
