How to uninstall Legacy Exchange 2003

[Dharmesh Arora]

I had recently done a migration from SBS 2003 to SBS 2008. All seemed to
go quite well except the un-installation part of the Exchange 2003 on my system. So, can any body tell me that how to uninstall Legacy Exchange 2003? Does any body knows about it? Kindly provide me the correct solution for the above issue. Any kind of help on the above issue would be appreciated.

For doing so, you need to go to the Configuration--> Services--> Microsoft Exchange--> [Exchange organization]--> [Administrative Group]--> [AG name] --> Servers --> [server name] --> Information Store --> Storage Group.

To remove the public folder mailbox and stores, on the Exchange 2003 or you need to use Exchange System Manager. If you remove the old mailbox server before users have had a chance to log onto the new server, then there's a good chance that Outlook will not be able to automatically redirect the users profile to the new mailbox location. You need to follow the below steps mention.
1. Expand the server, expand the storage group that contains the public folder store, right-click the public folder store, and then click Delete.
2. In the dialog box that notifies you that the public folder store is the default store for one or more mailbox stores or users, click OK to select a new public folder store. In the Select Public Store dialog box, select a public folder store on an Exchange 2007 server, and then click OK.

Before you remove a Microsoft Exchange Server 2003 server from a production environment that has multiple servers in the site, make sure that you know all the roles that are held by the server. Take steps to move those roles to another server before you follow the steps in this article to remove the Exchange Server. For example, the server may hold special roles such as site folder server or routing group master, or the server could be listed as a bridgehead server on a connector such as an SMTP connector or a routing group connector. If you do not transfer these roles to another server before you remove the Exchange server, you may experience adverse effects including the following:

• Mail flow may stop if the server is a messaging bridgehead server.
• Free/busy problems may occur if the server is the site folder server.
• Mail flow may be adversely affected if the server is the routing group master, because the link state data for the remaining servers in the site is not updated for each other and the link state data for the remaining servers in the site is not updated to other sites.
• Other adverse effects may occur depending on the role the server holds.

If this Exchange server is the only server in the site, role transfers are not an issue.
