We have a couple of old user accounts which were created under Windows Server 2K and Outlook 2003. The accounts were renamed at some point prior to upgrade to Server 2008 and Exchange 2010. The original (old) usernames on the accounts appear in Outlook 2010 when using automatic name checking.
It appears as though Outlook is obtaining this old information from the LegacyExchangeDN field, which contains the original users name. Is it possible to rename the LegacyExchangeDN field under the users AD object to match the correct display name? If not, how would I go about correcting the issue.
Thanks!
