Clearing the Outlook AutoComplete Cache


Recently, the company I work for switched our email host. So far, it has been great, with one exception. The "AutoComplete" feature that Outlook uses to show addresses while you type a new email was using old addresses based on the old host. Whenever you try to send to those addresses, they bounce back in your face. The easiest way around this is to dial-up the Outlook cache file and kick them nasty names:

  1. Close Outlook
  2. Click Start > Run
  3. *Type C:\Documents and Settings\YOUR-USERNAME\Application Data\Microsoft\Outlook
  4. Click OK
  5. Delete or Rename all files ending in *.nk2
Be sure to substitute "YOUR-USERNAME" with your system username.

You have rescued my sanity - the problem that has been plaguing myself and a colleague has disappeared.

Thank you, thank you, thank you.
