Hi, Can anyone advise if there is a way of attaching X509 certs to GAL entries, the method the company uses at the moment is to subscribe to Versign and purchase a cert, then when a signed mail is received add the sender to their contacts list. This seems a waste of effort when the entries are already in the Exchange GAL. Environment: Exchange 5.5 NT 4.0 Domain Outlook 98 & 2000 Oh...they would prefer not to use KMS or purchase the Verisign Exchange plug-in :) Thanks -- Enrico
