In Question ID 21639918 Changing a users name for the mailbox in Outlook was discussed, however after making that change the users name still shows incorrectly to email recipients.
I changed User Smith to User Jones in ADUC then went to Control Panel and used the Mail applet to rename the mailbox in Outlook, but when she sends mail the recipient still sees User Smith. I believe this is picked up by the name of the mailbox (visible in ESM). I have found no way to change that. Her PST is HUGE and cannot be lost. (yes it is backed up, but I am a coward) so deleting her mailbox and recreating it is a last resort. Is there some way in one of the highbrow programs like ADSI edit to rename it?
