The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine whether debug mode is enabled in ScanMail for Microsoft Exchange by Trend Micro:

HKEY_LOCAL_MACHINE\Software\TrendMicro\ScanMail for Exchange\CurrentVersion\DebugModule

If the value data for DebugModule contains one or more of the following strings, the Exchange Server Analyzer displays a warning:

  • HOST:1

  • CONFIG:1

  • MASTER:1


  • STORE:1


  • TCHER:1

  • MON:1


This warning indicates that debug mode is currently enabled for one or more ScanMail for Microsoft Exchange module.
