This past week fellow SharePoint MVP Yaroslav Pentsarskyy posted an excellent PowerShell script for doing bulk updates on the UserProfile properties via PowerShell. The Bulk Update SharePoint 2010 User Profile Properties is a great script that makes it extremely easy to populate any new fields that are not set to synchronize.
My team has been doing a lot of client work promoting the user of User Profiles for use within customizations or to drive business processes. For a quick overview check out my blog post Permanent Link to User Profiles – Driving Business Process or sit in on my Developing Reusable Workflow Features presentation at SharePoint Saturday NY on July 30th or SharePoint Saturday The Conference 2011 August 11-13th.
This also demonstrates another great example of the value that PowerShell can bring to Building and Maintaining a high functioning SharePoint environment.
