Other very viable option, as posted earlier in this thread, is to run OTRS on a tertiary domain.

Subject: [otrs] R: Latching onto Exchange Don't waste time considering this option. Seriously. I've had the same problem this summer, and I have tried to implement Openchange protocol. I have succeeded in connecting to mailboxes and in downloading messages on a local mailbox. I've also piped the mails collected through Postmaster script onto OTRS. I did a LOT of work but the issues remains simply too much to use this solution in a production environment. So definitely go and ask to enable POP3 or IMAP on per-mailbox basis: this is the only reliable way, now. If you really need it, your mail admins should (and could) do this. Period. Ciao, d.
