c#: Exchange Mailbox Processing

This is a windows service that processes mailbox on an Exchange Server. Since the introduction of Outlook Security feature, accessing certain properties (like email) will trigger the Outlook prompt. To circumvent this prompt, we are using Redemption Extended MAPI library to fetch outlook messages.

We can use a profile to login to the mailbox or use profile-less (LogonExchangeMailbox) method to login. As I am processing the mails in a mailbox, I am moving them to a Processed Folder. I am fetching all messages into an array and then sort them on date sent descending order.


All attachments are saved to the file system and a pointer is saved in the database.


The windows service that hosts this library has a timer which calls the StartMailBoxProcessor code on a user defined time intervals. This service is deployed to two servers with fail over capability.
