I am trying to run some logic as a user selects different folders in Outlook (e.g. - Inbox to a subfolder to another subfolder, etc.) I want to enable / dusable some commandbuttons, etc. The problem is that the event fires once and no more.
What is the best event to handle for this purpose Is it SelectionChange
Why would the event stop firing WHat could I have done wrong in my code
SelectionChange only fires once

Sounds a lot like "My button stopped working" problem as described here.
You need to make sure the object exposing the SelectionChange event is not a local variable inside your method. It is just getting Garbage Collected and you stop getting the event.

Misha is correct that this is a problem we have found before. You may also wish to take a look at our Outlook samples as they use the CommandBar OM to do the very type of thing you are attempting to do:

For example, in my tasks article, I have a global declaration for a custom menu item called _exportTasks. I use the FolderSwitch event, and in there I compare the ID for the folder to which the user has switched. If that ID matches the ID of the target folder, I enable the menu:
Private Sub _Explorer_FolderSwitch() _
Handles _Explorer.FolderSwitch
If _Explorer.CurrentFolder.EntryID = _
_mapiTasks.EntryID Then
_exportTasks.Enabled = False
Else
_exportTasks.Enabled = True
End If
End Sub
