Outlook is forgetting auto remembered / cached email addresses

We recently started noticing that outlook (2007) is no longer remembering some email addresses. So I open a new message, start typing the name of the person I want to email and it should bring up options of remembered email addresses. Unfortunately, recently people that I email often are dissapearing and I've gotten complaints from some of our other people as well. These are people we often email on a daily basis. What's causing this and how do I fix it? I'm assuming there are parameters somewhere for how the auto recall of email addresses works, I'd like to edit those parameters for fix whatever is faulty. FYI this is on two completely separate MS 2003 terminal servers.
Thanks!

Hello earth-traveler,

The nickname file where Outlook keeps the autofill addresses may be corrupt.  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.

.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!

So there are no settings that control how long it remembers a name? Does it just always remember? If outlook creates a new nk2 file does that mean it won't remember any previously typed users? Is there a way to repair a corrupt file as opposed to replacing it? Once the file gets corrupted, does it make sense that it would start randomly losing names?
