GetID(ABC334.PDF) is part of a macro I used to test the function I created to parse out the ID. I put in various strings to see what kind of results I would get. It's not part of the code that runs.

The document Inspection Feature? The only one I know is Files Inspect Document and that will tell you that there is potential personal information (hidden columns, etc.).

Normally when I see the code fail on this line
Set FldrIn = olNS.Folders(MailBox).Folders("Inbox").Folders(InFolder)
With this error message, "The attempted operation failed. AN object could not be found." it means I moved something from one Outlook Folder to another manually. The fix that works for me is to close Outlook and reopen it.
