The "This Is Spam" button is grayed in Unread Mail folders (w/Outlook 2003) (still).

It was working properly with NIS v18.1.0.37.

This became a problem when NIS v18.5.0.125 was pushed out. 

It is still not functioning with v18.6.0.29. 

The "This Is Spam" button is now functioning properly when looking at subfolders under the Inbox folder (This was also a problem with v18.5.0.125), but not when looking through the Unread Mail Folder. 

This is an absolutely necessary operation.
