client side

by Churdoo In reply to Exchange 2003 Deployment

What client side settings do you need to change? During a normal migration from E55 to E2K/E2K3, Outlook is automatically redirected to the new mailbox store location.

Here's one of many articles on "the net" regarding the migration. is a great Exchange Server resource and/or post back more questions as needed.

We plan on changing the host name of the new Exchange server. Will the migration know the difference?

in-place upgrade or migration?

by Churdoo In reply to Host Name Change

Will you be doing an in-place upgrade of the Exchange Server or a migration onto new hardware?

Likely migration onto new hardware, and if so, it would have to have a different server name anyway. The answer is yes, Outlook will find the new server. When you get to the part of the migration where you re-home user mailboxes, of course Outlook is not connected when you rehome. Next time Outlook starts, it looks to the old server because it doesn't know any better, so the old server automatically redirects Outlook to the new server for the rehomed mailbox - again, it's automatic. Thereafter, the Outlook profile has been changed and now always looks to the new server.

The key is, plan to leave the old server online for several days after the last mailboxes have been rehomed off of it for the purpose of redirecting users' Outlook to the new server; so if someone had a day off or was on vacation from the time you rehomed their mailbox, the old server will be online to redirect their Outlook upon their return.

Once you're confident that all or most of the Outlook profiles have been redirected, you may proceed with the retirement process of the Exchange 5.5 server and bring your Exchange org up to 2003 level to complete the migration.
