I am building a Powershell script to create a company synchronized email signature so I don't have to ask users to manually edit theirs when information changes. It is set up to grab the contents of the signature template file in the shared network drive and combine it with the personal signature located locally on each machine.
My idea was to run this is a scheduled task in an effort to have these updated no later than 24 hours after any potential changes in the template.
If the script fails, it writes to a log and ultimately emails me so I immediately can remedy any problems on a per user basis.
The script runs perfectly, as is, assuming I run it manually . If I run it as a scheduled task in the user's context (still me), it doesn't send the email notification.
I'll link the script, but what about the scheduled task would cause it to behave differently when it comes to the Send-MailMessage?
My environment is a Server 2008r2 domain running on Windows 7 clients.
