The information in this article applies to:
If you enter many friendly nicknames in your Personal, or Outlook Address Book, Microsoft Outlook 97 may not correctly resolve the least recently used entries.
Outlook caches nicknames; when you use a nickname, it moves to the head of the cache list. If you fill the cache, the least recently used nicknames are removed. If you try to use a nickname which is no longer in the cache, it may not resolve correctly.
For more information on how to clear the nickname cache, please see the following article in the Microsoft Knowledge Base:

Title : OL07: How to Clear the AutoNameCheck List
Microsoft has confirmed this to be a problem in Microsoft Outlook 97 for Windows. This problem was corrected in Microsoft Outlook 97 version 8.02 for Windows.
Outlook 97, Service version 8.02 improves the nickname cache the following ways:
HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Outlook\AutoNameCheck
NicknamePath = <full path to nickname file>
The new cache size defaults to a 64 entry limit unless you specify
another size in the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Outlook\AutoNameCheck
MaxNicknames = <maximum number of entries (defaults to 64 if key does not
exist)>
Additional query words: auto name check list
