Recall or replace a message you've already sent
This feature requires you to be using a Microsoft Exchange Server e-mail
account

After furious head scratching, Vanguard asked:

|| "recall" option in ms outlook 2000 or outlook express.

| The included help within Outlook itself when searching on "recall"
| should already mention that this features requires the use of the MS
| Exchange mail server. Without Exchange, the method used is to send
| yet *another* new e-mail trying to recall the first one, and it
| rarely works. See:

| Recall isn't even an option available in Outlook EXPRESS.
