Sorry if this is a silly question, but I am trying to work out a (temp) solution to enable outlook clients to access company/exchange email remotely over the internet using OUTLOOK (not OWA) ... (apparrently it is not available on exchange 2000 to use the rpc/http option..? Is this true..?) Here is what I came up with: (similar to iphone/imap/exchange) 1. Publish Exchange 2000 IMAPS (with a company/private Certificate) through ISA 2006... 2. Publish "smtp" to exchange server on a non 25 "forwarded port" ( we already have smtp/25 going to a seperate spam filter system) through ISA... 3. Outlook client uses IMAP/SSL(993) and smtp through the forwarded port number....(he has to say "yes" to the "certificate may be invalid" box...it is not a public certificate...) It seems to work...Am I missing something? Is this "secure" ? Is there a "better" way to have an outlook client access exchange2000 remotely over the internet? (with exchange 2000) (We do have OWA working...we have one user who has requested to use Outlook so he can share our email with his other POP email account (his private email domain) on one client ...I know it sounds confusing...) (We will be upgrading to Exchange 2007 later this year...) Thanks in advance !!
