Antivirus status shown as Unavailable (This version of Windows does not support antivirus detection)
Original KB number: 3190315
Symptoms
You have a program running that sends out automated emails in Microsoft Outlook. When doing so, you receive the following error:
A program is trying to send an e-mail message on your behalf. If this is unexpected, click Deny and verify your antivirus software is up-to-date.
The Outlook Trust Center Programmatic Access option shows your antivirus status as:
Unavailable. This version of Windows does not support antivirus detection.
Cause
Windows Security Center is not supported on server operating system versions. For this reason Outlook is unable to check antivirus status when installed on a Windows Server.
More information
Outlook depends upon the Windows Security Center (WSC) on the operating system to detect the status of the antivirus software on the machine. Since the antivirus status isn't listed within the WSC on Windows Server Operating Systems, it can't obtain this information that results in the message we see within Outlook. You can confirm it if you log into the Windows Server console. In the Action Center, you don't see any antivirus information.
