Q: My workstations were patched with 931386 10 days ago, my Exchange servers have 931386, but not 926666, can I use the Exchange Server tool or do I have to have my users run the Outlook update tool?

A: You can use either tool.  The Outook tool is used typically by individual users, either interactively or in quiet mode.  The Exchange tool is a wrapper for the Outlook tool and is typically used by administrators to rebase large batches of mailboxes.
