Hello,

We have run across an odd issue with our user base. we recently migrated a large group of users from another domain into ours. We will call the original domain @olddomain. When they received their new PC's in the new domain (we will call this @newdomain) they kept their old email addresses for about 3 months. if you open up outlook it will display at the very top in the middle that the user is steve.smith@olddomain.com. It will also show this as the mailbox name off to the left.
We have since changed all of these users email address to steve.smith@newdomain.com BUT in outlook it still displays as steve.smith@olddomain.com both at the top middle and the pane to the left.
Does anyone know a good way to change this via script (maybe kix or powershell) so that outlook displays the new email address?? Basically we want:

steve.smith@olddomain.com to be ---->steve.smith@newdomain.com

Thanks in advance everyone,
Vince
