When an alarm is sent to an email alarm handler, no email is received.
No email system alarms are indicated in Vista.
An entry in the b0warlog.txt is created and will look like this: "Mon May 21 10:40:27 2012 alrdisp >> Error while instantiating MAPI server: -2147221164"
It has been found that if using Norton 360 antivirus software, this prevents the mail handler file "tacalarmmailer.exe" from being installed. To check to see if this is the case, check for this file under the Vista 5.x.x default directory.
For Windows 7 and Windows XP the default path is C:\Program Files\Schneider Electric\TAC Vista 5.x.x.
Check for the file "tacalarmmailer.exe" in the TAC Vista installation folder, if this file is not installed the easiest solution is to disable the Norton 360 and reinstall Vista.
