XADM: Extension DSAVUADM Could Not Be Loaded Accessing a Mailbox

ID: Q223279

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

If you use the Exchange Server Administrator program to view the properties of a mailbox, you may receive the following error message:

Extension DSAVUADM could not be loaded.
The extension for MS Exchange Administrator CPU type c1031667 could not be loaded.

After you click OK, a window appears with Abort, Retry, Ignore. If you click Ignore, you can access the mailbox.

The following event may be logged on the server.

Event ID 2037
Source: System Attendant
Description: The file version \\Add-ins\Dsavuad\I386\Dsavuadm.dll installed by the local server is not current. Unable to locate the current version on any server in the site.

CAUSE

This behavior may be caused by the installation and removal of GroupShield Exchange on Exchange Server computers. When you open a mailbox object and all of its associated properties, including the Anti-virus tab that GroupShield creates, the Exchange Server Administrator program looks for the Dsavuadm.dll file to display the properties of the Anti-virus tab.

When you install GroupShield, it creates a public folder called Quarantine to place infected messages in.

Dsavuadm.dll is a Network Associates GroupShield extension.

RESOLUTION

Please contact the software vendor Network Associates (formally McAfee) about completely removing GroupShield Exchange from your Exchange Server computer, so that it does not affect other servers in the organization.
