All Barracuda Message Archivers, firmware versions greater than 2.0.
Barracuda Message Archiver features Exchange Stubbing. This document attempts to explain what Exchange Stubbing is and its benefits.
Exchange Stubbing is a process where the Barracuda Message Archiver interacts with your Microsoft Exchange server via a Microsoft protocol called MAPI. During this process the Barracuda Message Archiver searches for emails that match a criteria that is set by you. An example of this criteria would be all emails that are larger than 5 MB and older than 6 months. Attachments are stripped from emails that match the policy and are replaced by a stub.
Benefits of Exchange Stubbing
1. Exchange Stubbing allows administrators to realize tremendous space savings since the attachments are removed from Exchange and replaced with very small stubbed emails.
2. Postpones upgrading to a more expensive license of Microsoft Exchange.
3. Email users appreciate the fact that emails are still in the same folder as they had placed it in.
4. Access to stubbed emails is seamless.
How to Setup Exchange Stubbing
Administrators can setup Exchange Stubbing by logging into the Barracuda Message Archiver and navigator to Mail Sources>Exchange Integration. This page allows you to setup the policies which controls which emails get stubbed.
Within Outlook, stubbed emails are displayed with a different icon. When you try to forward a stubbed email, attachments are automatically included. Even opening the email by double clicking the email has the same behavior. In the preview pane a list of attachments shows the original attachments. User have the ability to 'un-stub' emails for a period of 30 day (for offline access) and also selectively 'stub' messages.
