Re-Enabling PST functionality in your Outlook session.

Scenario:  You cannot open or create a PST within your Outlook.  The options are missing OR it does not allow to complete a PST operation. If you try to Integrate SharePoint with your Outlook, you may receive the following error:

Outlook cannot add the folder because creating a new Outlook data file (.pst) file isn't allowed on this computer.

Solution:  The registry has a DisablePST value that is set to not allow PST functionality.  The data for this key is:
0 = Enables PST functionality
1 = Disable PST Functionality Completely
2 = Disables creating PST's, but allows to open PST's.

1. Open up the registry (regedit).
2. Click on Edit-Find and type in DisablePST. Perform a find.  Keep hitting F3 to perform a 'find next' if this doesn't take you directly to the key.
3. Delete the Key or Set it to the corresponding value.  Deleting the key or giving it a 0 are one in the same.

Searching it take you to a location similar to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\<version>\Outlook.   This location may be different if using a 64 bit version of Outlook.
