The messaging/mail archiving solution we have is facing some new challenges for the client after they added the multiple domains from the recent acquisitions. Using Exchange Servers, now this company has multiple domains, one domain hosts the Active Directory for authentication, and other domains host the actual mailboxes, our method to logon to the mailbox fails. We assumed sending username/passwd directly to the Exchange Server where the mailbox resides should just work, but it doesn't. What do we need to do to access to the mailbox in this environment? We use IMAP/Pop3/WebDAV protocols to access Exchange mailboxes.
