Scheduled task to execute local script that has functions to execute a remote script

i want create script run every 3 or 4 hours. when executes, monitors user's mailbox new mail items containing "update available" in subject line. if find new mail item keywords, establishes connection remote server , executes update script located on remote server.

i've tried using invoke-command, doesn't seem work when try schedule script execute task. know of other methods this? below code have:

first of all, assume script works when run outside of scheduled task?

possibly long shot, since you're using

 $pass = convertto-securestring password -asplaintext -force

you've generated encrypted version of password elsewhere insert script. have made sure generated encrypted string using same profile 1 being used in scheduled task?

when did similar found same issue, though in case further complicated fact calling script our monitoring system. created script spit out encrypted string text file, , found when ran ise got 1 output, when ran monitoring software got different one.

if you're unsure easiest way use :

  $password = "<password>" $secure = convertto-securestring $password -force -asplaintext $bytes = convertfrom-securestring $secure $bytes | out-file c:\securepassword.txt  

encrypt password , spit out encrypted version text file, , run script same way you're trying run main one. if resulting string different 1 you're using that's answer, , can replace string new working scheduled task.
