Issuing X.509 V3 Certificates on Mail Between Sites

If you have installed KM server in an organization with multiple sites and are issuing X.509 V3 certificates to clients, you must first install Microsoft Exchange Server 5.5 Service Pack 1 on at least one computer in each site within your organization. X.509 V3 certificates cannot replicate across sites without an updated installation in each site.

To enable X.509 V3 mail between sites, you must also complete the following procedure in each site.

1. In the Administrator window, choose Configuration.
2. Double-click DS Site Configuration, and then select the Attributes tab.
3. In the Configure box, select Inter-site replication.
4. In the attributes list, select the Tagged-X509-Cert box, and then choose OK.
