Nickname cache - LegacyDN

Outlook caching is a convenience, as well as a curse. Here is a quick registry setting that will turn off the Nickname Cache for all those LegacyDN issues that pop-up.
------------------------------------------------------------------------------------------------
The registry change, listed below, will turn off your nickname cache. It does not delete it and if you set the value back to 0 it will still be there.

Note that the AutoNameCheck key and the NoNicknames value are not created by default, at least no since Office 97 (8.0). You must make the change at the appropriate level for the Office version, 10.0 is Office XP and 11.0 is Office 2003.


[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\AutoNameCheck]
"NoNicknames"=dword:00000001
