MS06-012 Unmaps PSTs - "Not implemented" error on New, Reply, ...
 

After installing MS06-012 on a Windows XP Pro system running both
Outlook 2002 (aka Outlook XP) and Outlook 2003 - Everything in Outlook
2003 running fine, but any New, Reply, etc in Outlook 2002 pops up a
"Not implemented" error dialog.

Fix for me turned out to be that the patch had upmaped my PSTs in the
current profile. Start - Control Panel - Mail. Look for any PST
mappings that are undefined/not specified. Remap them back to the right
file.
