Document Expiration Monitor - Automation with PowerShell Script
Requirement: There are bunch of document libraries with several documents loaded on various site collections. We've to monitor their expiry date based on a column and send e-mail notification to all members of a SharePoint Group. Also all E-mails sent should be logged in a tracking list.
Solution: Lets write a PowerShell script to scan required document libraries and send E-mail. BTW - Its for MOSS 2007 (But the script works on any SharePoint versions, of course!)
