Hi all, we've got a new telephone number in our company and I have to change all phone numbers in the active directory orglobal address book in exchange. For example: All phone numbers must be changedfrom12345-xxxxto 3423123-xxxx, where xxxx is the users extension. Please help!

Hi,The following Exchange Management Shell code should give you an idea of how to approach this. It worked for me on limited testing.foreach ($user in $(get-user | where-object {$_.RecipientType -eq "UserMailbox"})){set-user -Identity $user.Identity -Phone $($user.Phone -replace "12345", "54321")}I hope that helps.
