Outlook autocompletes frequently used email addresses or aliases that is, addresses or aliases you enter repeatedly are cached and appear automatically after you type the first few letters. Occasionally you need to delete one of the autocomplete addresses e.g., when it is a misspelling or an alias changes. You can either delete individual cached autocomplete addresses or empty the entire cache. Follow the appropriate steps below. Delete an individual address from the autocompletion cache 1. In Outlook, start typing the address as usual until the list of autocomplete addresses come up. Often the list contains only one address, but there may be many more. 2. Use the arrow keys on the keyboard to select the address you want to delete. If the list has only one item, that item should already be highlighted. 3. Press the Delete or Del key. Clear the entire autocomplete cache Occasionally, especially in the case of misspellings, you have to clear the entire autocomplete cache. Occasionally that cache is corrupted, and attempting to delete an individual entry fails. In other cases, you may want to delete so many entries that itand39s easier to clear the whole autocomplete cache. To clear the cache, follow these steps: 1. Close Outlook. 2. Configure Windows to show hidden files. 3. Search for files on your hard drive that contain the keyword .nk2. The specific steps depend on your version of Windows and in Windows XP, on how you have your Taskbar configured, but in any case, you need to enter .nk2 in the search field. 4. In the search results, find the .nk2 file with the name of the profile that you want to reset. Rightclick the filename and select Rename. For example, if your Outlook profile is named dvader, rightclick dvader.nk2 and select Rename. Keep in mind that, unless you specifically named your Outlook profile after your username, you probably wonand39t find yourusername.nk2 in the search. You will have to know your profileand39s name to identify the correct file in the search returns. In most cases, only one file will be found. 5. Change the fileand39s extension to anything other than .nk2. For example, if the file you located is named dvader.nk2, change it to something like dvader.bak or dvader.old . CCIT recommends against deleting the .nk2 file entirely. If Outlook wonand39t launch, or something within Outlook malfunctions, you may need to recreate your .nk2 file by restoring the .nk2 at the end of the renamed fileand39s name. 6. Restart Outlook. A new .nk2 file will automatically regenerate.
