are you referring to NK2 cache?
do you mean outlook do not remember the email address once the user send emails ??
Rajkumar KamathIT ManagerAuthor Commented:
yes. outlook doesnt remeber the cached email address by first name last name format. only by emailaddress. and seems to be pretty much inconvenience for the user to type the first letter, select the email address and compose the message.

it shows properly in the right format for all the other users.

created local contact for the email addresses , cleared the old ones and send email individually
