Groupwise & Exchange

[murat]

Dear All,

Situation:
I need to have full communication ( mail, calander, appointments etc. ) between my organization ( Exchange) and an other one (Groupwise)

Does somebody has a good advise from real world before I decide which option to implement.? Or any other idea?

Options

Connection through an Novell GroupWise Interface Server (GroupWise gateway)

Connection through an SMTP connector/ GroupWise Internet Agent
( SMTP gateway)

Connection through an X.400 connector/X.400 Agent
( X.400 gateway )

Comparing the options above for the following criteria:

Layout
Communication
Investment
Traffic
Conversion
Security
Continuïty
Administer
Flexibility
Adresbooks
Implementation
Troubleshooting

What will be the best solution?

greetings
