You receive a "Error reading nickname cache" error message when you use the Outlook Nickname tool in Outlook 2002 (318827)


The information in this article applies to:

  • Microsoft Outlook 2002
This article was previously published under Q318827

SYMPTOMS

When you run the Outlook Nickname tool (Nick2k.exe) in Outlook 2002, you receive the following error message:
Error reading nickname cache. Perhaps the file does not yet exist.

CAUSE

This problem occurs because the Outlook Nickname tool for Microsoft Outlook 2000 is incompatible with Outlook 2002. The nickname cache in Outlook 2002 stores items (for example, entries created by the AutoComplete feature) that are not found in the nickname cache in previous versions of Microsoft Outlook.

RESOLUTION

An updated version of the Outlook Nickname tool that is compatible with Outlook 2002 has been created, but you should review the details in the "More Information" section of this article before you decide to obtain the updated version. The new AutoComplete feature provides functionality that makes the use of the Outlook Nickname tool basically unnecessary.

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

To resolve this problem, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

WORKAROUND

To work around this problem, delete a name that is stored in the nickname cache. To do this:
  1. Open a new message.
  2. In the To box, type the first three letters of the name that you want to delete from the cache. The list of cached names that start with these three letters automatically appears below the name.

  3. Use the arrow keys on your keyboard to move the selection in this list to the name that you want to delete.
  4. Press the Delete key.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

The AutoComplete Feature and the Outlook Nickname Tool

If you are using previous versions of Outlook, you can use the Outlook Nickname tool to verify recipients' e-mail addresses and to remove any incorrect entries in the nickname cache. In Outlook 2002, the chance of incorrect entries is rare or even non-existent. The reasons for this are as follows:
  • The AutoComplete feature overlaps and replaces the older Nickname functionality. Although the nickname entries that you created in previous versions of Outlook may appear in the nickname cache, each nickname entry is replaced with an AutoComplete entry during the first use of Outlook 2002.
  • The AutoComplete entry resolves an e-mail address or alias to the full name or the display name of a Microsoft Exchange recipient or Outlook contact. This is more accurate than an arbitrary nickname.
  • If the AutoComplete feature is turned on, you can visually confirm the recipient after you type at least three characters of the name. The AutoComplete entries always resolve based on the full name or alias. This lowers, if not completely removes, the possibility of sending a message to an incorrect recipient.
