I have a question regarding Exchange server's IMAP support. I want to write a client application that talks to the exchange server using IMAP. The client application should authenticate with the server using a super user account and then should be able to select/scan individual user mailboxes and then if an event of interest has happened on the selected folder than it would send a notification out to the client with the contents of that event (i.e. e-mail arrived).Now, the key to this problem is to be able to authenticate as a super user and being able to scan user mailboxes using the super user credentials. I want to do that so that i maintain a pool of connections with the exchange server as against one authenticated imap connection with individual user credentials. Now, on the exchange server, I can pretty much create a mailbox and give me the read privs at the mailbox store level. All is fine until then, the problem is that when i then execute an imap namespace command to find out how i should select other user's mailboxes, exchange server doesn't tell me anything. The question is, does exchange server support namespaces in that if a client executes a namespace command (having authenticated as a super user), can it somehow expect to see a response from the server in which the second argument (which in IMAP should be the namespace for OTHER user's mboxes) contains other user's mbox namespace. If this is not possible, how can an super user who has access to all the folders, select individual user mailboxes.
