Environment

Endpoint Security (ENS) Threat Prevention 10.x
Microsoft Office 2010 and 2007
Microsoft Outlook 2010 and 2007 Trust Center

Microsoft Antivirus API

Problem

Outlook Trust Center can report an inconsistent Antivirus status under Tools, Trust Center, Programmatic Access.

When this issue occurs, systems with valid ENS installations might report either of the following:

Antivirus status: Invalid

Antivirus status: Valid

Cause

Outlook Trust Center is not a supported feature of ENS. Outlook can sometimes detect the antivirus program via Windows Security Center. So, if the Security Center service is stopped, Outlook might not recognize ENS.

NOTE: If your Windows 10 version is earlier than 1709, this issue occurs unless you apply the Windows Security app Microsoft KB:

Solution

ENS does not currently support Outlook Trust Center. Outlook users are sent to the Windows Security Center for the status of the antivirus product. ENS continues to correctly scan emails regardless of the status shown in the Outlook Trust Center.

NOTE: Our customers report that starting the Windows Security Center service often allows Outlook to show the correct status in the Trust Center.

Customers can use the following workaround, but there is no guarantee that this workaround resolves the issue.
