removed from your Exchange server and replaced with the stubs so that any requests to access the file or message is automatically redirected to,
and served from, the Barracuda Message Archiver. A short message containing the names and sizes of the stubbed content is placed in every
"stubbed" email, along with a hyperlink from which users can easily access the attachments regardless of what email client is used, including
Outlook Web Access and mobile devices.

End-User Controls
The Barracuda Message Archiver Outlook add-in is available to all users of Microsoft Outlook 2003 and higher, and retrieves the attachment and
places it inline to ensure that email messages and attachments appear as they would prior to Exchange stubbing. The add-in can also be used to
temporarily unstub and re-stub specific messages. Any message unstubbed via the add-in remains so for 30 days, after which time it is
re-stubbed during the next automatic stubbing process.
Unstubbing
Unstubbing a message causes the Barracuda Message Archiver to place the attachment back into the body of the message. This is most useful
when individual end-users are on the road and need immediate access to all attachments in a message even while not directly connected to the
mail server. Any message that is unstubbed by the user remains so until it is re-stubbed by that user, or after 30 days; it is not re-stubbed by
If there are no attachments in the message, then nothing is stubbed and the entire message is left intact.
