I am getting an error that i am certain is being caused by the auto-complete cache having old info in it. I saw a posting about clearing this but it was for Exchange which i don't use. Can you tell me how to clear or reset this cache?

    Hello dheymann,

    If you want to delete one item, right click on empty area of To field and hight the name you want to delete.  Hit the Delete key.

    To reset the whole cache, the names are kept in a NK2 file.  With Outlook close, search for *.NK2 and rename the file.  When Outlook opens, a new one should be created once a user types a name in the To field.

    In Windows XP, .NK2 file is located in
    C:\Documents and Settings\\Application Data\Microsoft\Outlook folder. It is a hidden file. Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders".  Click OK.

    In Windows Vista, file is located in C:\Users\\AppData\Roaming\Microsoft\Outlook

    Hope this helps!
