I had an installation of exchange 2003 that quit working. I only had a few mailboxes (mostly just a test environment) on that server, one of which was my main account. I built a new installation of exchange on a new server and it is running fine for any NEW user i create. however, existing users are still pointing themselves to the old exchange server I had up and have since removed. is there a way to change the home server field on the Exchange General tab (on the properties page of the ADUC user)? or am i stuck deleting that user and re-creating it? if I right-click and select exchange tasks, the only I option I get is to remove exchange attributes. I know I screwed up my not migrating the mailbox from my old server before removing exchange from it. just wondering if I can correct my mistake. TIA Charast

You can do it by editinng below three attributes on problematic user accounts through ADSIEdit.msc Open the ADSIEdit -> expand Domain Configuration partition -> go to the user object whose attributes you want to change -> Right click and Properties homeMTA homeMDB msExchHomeServerName Give the correct entries for the correct server and database here (you can compare some users these three attributes which are working fine on same server and database)

Hi Charast, You can run Remove Exchange Attributes and recreate the mailbox on the new Exchange server. Then update email address by using RUS. This method does not need to recreate an user. Mike

I changed the homeMTA and the msExchHomeServerName attributes only. since it was a new mailbox I was setting up and testing with OL07, i did not need to change the homeMDB since OL would be creating that when I went thru the mailbox setup (the old mailbox that got removed when I killed the old server did not contain mail I needed anyway). OL found my mailbox name right away and everything is good. emails are going in and out now. thanks again! charast
