There is a lot of documentation out there for interacting with Microsoft Office including Outlook, Excel, Word, etc with Visual Basic for Applications (VBA). A lot of time you may only be able to find VBA examples. VBA's require template files to be sent to the desktop and are a real hassle when trying to automate across multiple machines.
There are not many A to B examples of translating VBA to PowerShell so I took a problem I had solved in the past and presented the before and after. Hopefully it will provide enough information to allow others to convert VBA code into PowerShell for their scenarios.
