Open your contacts by either clicking Contacts icon on the left pane, or choose Go> contacts from the toolbar. For each contact do the following:
Double click the contact name, choose the “Details” Tab, and in the nickname field type some nickname, click save and close.
For example for contact “Gopesh Tiwari”, double click and then in details choose nick name as “gt”, save and close
Now when you want to send a mail to Gopesh Tiwari, type gt; (observe the semicolon mark) in the TO: field and then fill subject and type the message. You will observe that Outlook replaces the nickname “gt” by “Gopesh Tiwari” as soon as you leave the To: field.
Open your addressbook
using the address book icon
(like a
small diary). You will find this icon to the left of “type a contact to
find” In the window labeled “address book” click
tools->options. In the “show this address list first” select Contacts. Then in “when sending mails check names using these…” ensure that “contacts” is on the top. You can change the order by clicking on “contacts” and then clicking the up arrow on the right. After this close your Outlook and restart it.
Note: You can use the nicknames using the OWA also
