Barracuda Backup

Why do I receive a connection failure when I try to setup Exchange 2007 Message Level Backup with the Yosemite Backup Server?

Solution #00004006



Barracuda Backup Servers, all firmware versions and associated MS Exchange 2007 Servers running Yosemite Backup, version 8.7.


Barracuda Backup Server Message Level Backups require Microsoft Outlook Web Access (OWA) be enabled on the Exchange Server. Microsoft Exchange Server 2003 uses the virtual directory entitled /exchange for OWA server objects. The release of Exchange 2007 renamed the virtual directory to /owa, as a result the CN=HTTP container under CN=Protocols is missing for the server object and the virtual directory for /exchange is missing.


Microsoft has provided a solution ( to this problem, as follows:

  1. Click Start, click Run, type adsiedit.msc (a windows 2000 support tool), and then click OK.
  2. Expand the following objects under the Configuration directory ? CN=Configuration, expand CN=Microsoft Exchange, expand CN=<OrganizationName>, expand CN=Administrative Groups, expand CN=Exchange Administrative Group, expand CN=Servers, and then expand CN=<ServerName>.
  3. Right-click CN=Protocols, click New, and then click Object.
  4. In the list, click msExchProtocolCfgHTTPContainer.
  5. Click Next, and then click HTTP in the Value box.
  6. On the affected Exchange 2007 server, start Exchange Management Shell (available from the Microsoft Exchange Server 2007 program menu).
  7. Run the following cmdlet to create the virtual directory in IIS and in Active Directory. Cmdlets are commands that are run from the command line in the Exchange Management Shell.
    New-Owavirtualdirectory -owaversion:exchange2003or2000 -virtualdirectorytype mailboxes -name exchange
  8. Use the new-owavirtualdirectory cmdlet to re-create the public virtual directory and the exadmin virtual directory.
