This article outlines the steps necessary to remove the first Microsoft Exchange Server computer installed in an Exchange Server site.
In addition to any mailboxes and public folders, by default the first server in a site contains and is responsible for the site folders. Site folders consist of the Offline Address Book (OAB) folder, the Schedule+ Free Busy Information folder, and the Organizational Forms folder, if one exists. Other servers installed in the site rely, by default, on the first server for this information. For example, in order for the third server in the site to generate the OAB, it must make a connection to the first server. If you remove the first server in the site without performing the steps in this article, the data contained in these site folders may be inaccessible or lost.
The first server in the site is also, by default, the routing calculation server. The routing calculation server is responsible for updating the site's Gateway Address Routing Table (GWART). You also must reassign this responsibility before you remove the first server from the site.

IMPORTANT: If there are any users or public folders (non-site) homed on this Exchange Server computer, you must move the mailboxes to another server in the site, and you must replicate any public folders to other servers in the site, to ensure that you do not lose data. Please refer to the Microsoft Exchange Server Administrator Guide, chapters 12 and 15, for more information.

To Include Schedule+ Free Busy Information:The Schedule+ Free Busy Information site folder is repopulated as users log on to Schedule+ and generate changes. During this period some users' free and busy information is temporarily unavailable.
Until a user logs on and makes an appointment (a "busy" time) there is no free and busy information to view.
