SUMMARY
In some cases, the Microsoft Exchange Server Administrator may need to delete all SMTP proxy addresses for all users in the Microsoft Exchange Server site. By default, SMTP addresses are created for every user based on the Organization, Site, and Server name.

This article describes the different procedures for deleting SMTP addresses for all users in Microsoft Exchange Server versions 4.0 and 5.0.



Exchange 4.0
Microsoft Exchange Server version 4.0 allows an administrator using the Administrator program to delete the SMTP addresses for the entire site or server.

To do this using the Administrator program, perform the following steps:


 * 1) In the Administrator menu, click Site, and then click Configuration.
 * 2) In the Site Addressing properties dialog box, click the Site Addressing tab, and then click Remove.
 * 3) When you are prompted for the e-mail address type to delete, enter SMTP and click Yes in the Warning dialog box.

NOTE: By doing the above procedure, you remove ALL instances of SMTP proxy addresses for a user on the site or server. You also disable Site Addressing to regenerate SMTP addresses for the site or server even though the SMTP option remains in the Site Addressing properties. This only reflects changes for new users created after you have selected to delete the addresses.

Exchange 5.0
Exchange 5.0 does not allow the deletion of SMTP addresses on the Site Configuration level. The only way to remove SMTP addresses is to delete them manually for each user.

NOTE: It is possible to remove all SMTP addresses without removing the SMTP attribute for all users by blanking the address instead of deleting. Refer to the Microsoft Knowledge Base article 170378, XADM: Blanking SMTP Addresses for All Users.
