processes the request and returns the attachment data to the BlackBerry Attachment Connector. The BlackBerry
Enterprise Server requests the attachment data from the BlackBerry Attachment Connector and sends the
attachment data to the user's BlackBerry device.
By associating multiple BlackBerry Attachment Service instances with a single BlackBerry Attachment Connector, you
can create a BlackBerry Attachment Service pool. You can configure different BlackBerry Attachment Service
instances as dedicated servers for processing specific file formats. For example, you can create a BlackBerry
Attachment Service pool that contains three BlackBerry Attachment Service instances, where one instance processes
email message attachments that are in audio file formats, one instance processes email message attachments that
are in image file formats, and one instance processes email message attachments that are in all other file formats.
For more information about configuring high availability for the BlackBerry Attachment Service, see the BlackBerry
Enterprise Server Planning Guide.
You can change how a BlackBerry Attachment Connector processes attachment requests that it cannot deliver to a
BlackBerry Attachment Service, and you can change how a BlackBerry Attachment Connector restores a lost
connection to a BlackBerry Attachment Service.

The BlackBerry® Attachment Connector sends requests to view attachments from users' BlackBerry devices to a
BlackBerry Attachment Service. You can change how a BlackBerry Attachment Connector processes attachment
requests that it cannot deliver to a BlackBerry Attachment Service.
Depending on the number of users in your organization's environment, if you change the BlackBerry Attachment
Connector settings, your organization's environment might experience a performance impact.
