Many corporate offices use Microsoft Exchange servers, whether in-house or hosted, to provide the valuable collaboration tools they depend on. email2 integrates seamlessly with all implementations of Exchange, right out-of-the-box. No special configuration on either end!
When a user sends or receives an email2 Message using the email2 Toolbar for Outlook, that message is automatically saved into that user's Exchange mailbox (or PST file). Exchange can implement any existing process on the message including encryption and archiving procedures.
In the event that your organization stops using email2, all the email2 Messages are still stored in your Exchange server. You never lose control of the data.
