In Outlook 2002 and 2003, what is AutoComplete Addressing?
Outlook 2002 and 2003 come with an addressing feature called AutoComplete, which is turned on by default. AutoComplete remembers addresses you have recently used; when you type a minimum of three characters which match previously used addresses, it will complete the address with a unique match from the list of remembered addresses. These addresses are already resolved, and thus ignore any lookup in the Global Address List (GAL) or your Contacts.
Note: When you enter an address in the "From:" field,
it is critical that it resolves to the GAL, not to
the SMTP address; for example, "Fudd, Elmer" instead of
efudd@indiana.edu. If the "From:" field
resolves to username@indiana.edu, you will
see a permissions error. If you watch as you type the username, and
see username@indiana.edu display in the list,
highlight it and delete it. This effectively removes it from the list
of remembered addresses.
To disable AutoComplete:
- From the Outlook
Toolsmenu, clickOptions....
- Click the
Preferencestab, then clickEmail Options....
- Click
Advanced Email Options..., then deselect the checkbox next toSuggest names while completing To, Cc, and Bcc fields. Then clickOKto close each of the three open windows.
