Reset Outlook nicknames

Microsoft Outlook maintains a nickname list that is used by the automatic name checking and completion features. The nickname list is automatically generated as you use Outlook. If the nickname cache becomes corrupted, Outlook may not be able to identify recipients, may offer incorrect recipients when automatically completing the e-mail address, or may send the message to the wrong person. Additionally, if one of your contacts changes their email address, Outlook will continue to remember their old address indefinitely. Use this procedure to reset the Outlook nickname cache in MS Windows XP:

  1. Quit Outlook
  2. Click Start and then Search
  3. In the left-side panel of the Search Results window, click All files and folders
  4. In the All or part of the file name text box, type *.nk2
  5. In the Look in selection box, select Local Hard Drives
  6. Click More advanced options and click the Search hidden files and folders check box
  7. Click Search
  8. Once found, right-click the appropriate NK2 file (most probably “Outlook.NK2”) and select Rename
  9. Rename the file to Outlook.bak and then press Enter
  10. Close Windows Explorer
  11. Launch MS Outlook

Outlook will now generate a brand new nickname cache.
