The Microsoft® Exchange Server Analyzer Tool queries the Win32_Service Microsoft Windows® Management Instrumentation (WMI) class to determine whether Trend Micro ScanMail for Exchange is installed and if the ScanMail_MailAction service is running on the Exchange computer.
The Exchange Server Analyzer also queries the Win32_Service WMI class to determine whether the value set for the Started key in the Microsoft Exchange Information Store service is set to True or False.
A value of False indicates that the Microsoft Exchange Information Store service is not running on this Exchange Server computer. A value of True indicates that the Microsoft Exchange Information Store service is running.
If the Exchange Server Analyzer finds that the Microsoft Exchange Information Store service is running, and that Trend Micro ScanMail for Exchange is installed, but the ScanMail_MailAction service is not started, a warning is displayed.
Trend Micro ScanMail for Exchange provides antivirus protection for Exchange Server. Some reasons the Trend ScanMail service may have been stopped, together with solutions, are listed here.
- The software you are running on your Exchange server may be an
evaluation or trial version that has expired. In this case, you may
need to reinstall Trend ScanMail. At a minimum, to continue using
the software, you must activate it.
- An administrator may have unintentionally stopped the
ScanMail_MailAction service. Verify that the service is set
to start automatically, and then start the service.
- A malicious worm, virus, or other program may have stopped the
service. Verify that the service is set to start automatically, and
start the service. If the service continues to stop unexpectedly
without relevant error events, verify that the computer is not
infected with a malicious worm and disinfect the system if
It is generally recommended that you deploy antivirus software designed for messaging systems at either the Simple Mail Transfer Protocol (SMTP) gateway or at the Exchange servers that host mailboxes. For the most protection, run antivirus software at the gateway that scans the incoming MIME messages, and a scanner on the Exchange server that uses VSAPI 2.5. Additionally, you should be running client antivirus software on the user desktop. If you are running antivirus software designed for messaging systems (it can parse and scan MIME) at the gateway or on the Exchange server, running a file-level scanner at the desktop is sufficient.
To start the ScanMail_MailAction service
Open the Services MMC snap-in.
Right-click the ScanMail_MailAction service, and then click Properties.
On the General tab of the ScanMail_MailAction property page, make sure the Start-up type is set to Automatic. If it is not, set it to Automatic, click Apply, and then click OK.
Right-click the ScanMail_MailAction service, and then click Start.
Close the Services snap-in.
