You need to install MSOffice on your server for the interop to work.

This only worked on your local machine as it was client and server, and the website was running under your local account. To get this working on a remote server you'll need Outlook installed, which isn't supported by Microsoft, it's not going to work on an asp.net page. Even if you do install Outlook (ignoring the legal and licensing issues) and don't mind restarting IIS every 5 minutes as it keeps hanging, you still can't access the client's calendar as your code is not running under the client's context.

Basically, what you're doing isn't going to work. Outlook is a client application, not a server component. If your calendars are held in Exchange then use the Exchange Web Services (EWS) to interact with them, likewise if you are reading\sending email then use pop3\IMAP\SMTP\EWS components that will work under asp.net. You will not get your site working the way it is currently written, you need to redesign it.
