This article refers to Barracuda Message Archiver Legacy Release firmware or higher, and Microsoft Exchange Server 2010 SP1 with shared or delegate mailboxes.
The Barracuda Message Archiver's Shared Mailbox Support feature allows a Barracuda Message Archiver user access to email based upon Microsoft Exchange Server's shared mailbox capability.
When a user searches for emails in the Barracuda Message Archiver web interface, Barracuda Archive Search for Outlook, or through a Barracuda Message Archiver Mobile Application, the search results include emails from both the user's mailbox as well as all mailboxes shared with that user.
Shared Mailbox Configuration
On your Exchange Server you can create a shared mailbox for use by multiple users. For Exchange Server 2010 SP1 and higher, the Barracuda Message Archiver supports shared mailboxes when one of the following is true:
- A user is assigned full access permissions to another mailbox via the Exchange Management Console (EMC). This action populates the LDAP attribute MSExchDelegateListLink, and is used to determine shared mailbox access.
- A user is assigned delegate access to another mailbox via Microsoft Outlook. This action populates the LDAP attribute PublicDelegates, and is used to determine shared mailbox access.
Conversely, the Barracuda Message Archiver does not support shared mailboxes if Send As permissions are enabled from the EMC. This action does not populate any LDAP fields, preventing the Barracuda Message Archiver from determining shared mailbox access.
Shared Mailbox Support - Auto-Mapping Enabled
Shared mailbox support is easily available when auto-mapping is enabled. Auto-mapping is typically enabled by default on Exchange Server 2010 SP1 and higher.
Shared Mailbox Support - Auto-Mapping Disabled
If auto-mapping is disabled on the Exchange Server, specific AD attributes that the Barracuda Message Archiver uses to determine shared mailbox details may not exist. Therefore, to ensure shared mailboxes function properly, you must manually create specific AD attributes. The Barracuda Message Archiver uses either the MSExchDelegateListLink or PublicDelegates AD attributes for a user to determine what mailboxes are being shared.
