Outlook's autocompletion cache is maintained in a separate file, commonly called
the nickname or NK2 file. You can manually delete an entry, if you're lucky
enough to activate the drop down list in the To or Cc fields. You can use the
arrow keys to select the address and then press the Delete key to remove it. You
can also delete the existing NK2 file (or rename the extension) to completely
clear the cache and start with a clean cache file. Do this with Outlook closed.
When you open Outlook again, a new NK2 will be generated.

Here's a few good reads on this subject:

If you delete or rename the existing NK2 file and then you wish to repopulate it
with the content of your Contacts, here's a procedure I found using Google that
reportedly works well to populate the NK2 file again:

You can quickly and easily create a new NK2 (autocomplete file) using the
following work-around:

In Outlook, go to tools, options, mail setup, send/receive. Uncheck the
"Send immediately when connected" box. Next, press the Send/Receive Button
(in Options) and uncheck "Schedule an automatic send/receive". Next
disconnect your computer from the internet by removing your network and/or
telephone connection. Open a new e-mail, press the bcc or to or cc button,
select the contact folder you would like to bring into your NK2
(autocomplete) file. Select all names by highlighting first and last
contact and then add them by pressing the OK button at the bottom. With
your computer disconnected, press the send button. This will automatically
populate your autocomplete file with all of the selected e-mail addresses.
Next, go to your Outbox and delete the e-mail(s) that you just created. Go
back into your Tools, Options, Mail Setup, Send/Receive and change your
options back to the original settings. Remember to put your mail settings
back and plug in your removed cables.

Good luck!
