Improve Your Message Mobility
Outlook generally displays only one folder at a time. However, to help facilitate easier transfers from folder to folder, it is possible to open multiple windows with different folders. To do so, just right click the folder icon and click Open in New Window from the context menu.

Customise Your Startup
If the Calendar or the Inbox folder is all that you start Outlook for, then make it your default folder. You can choose between Today, Inbox, Calendar, Contacts, Task, Journal or Notes to start up when you run Outlook. Click on Tools > Options > Other. Click Advanced Options and select the folder that you want to start with in the Startup in this folder dropdown list. Click OK to apply the changes.

Display Contacts by nickname
If you have a contact whose nickname means more to you than his or her real name, you can display the entry by nickname instead of the real name. To look up a contact using a nickname, open the person's entry in your Contacts list and in the "File as" area, type the nickname you want to use.

E-mailing Notes
Sending a note in your Notes folder to someone via e-mail takes only a right click. Select the note you want to forward, right click it and click on Forward. A new e-mail dialog will pop up with the note attached.

Archive Your Data
An unnecessarily huge inbox folder can clog up resources and increase loading time. If you do not wish to delete messages from your folder, you can archive them to a separate file. Dragging and dropping the selected files from the folders into archive folders can do this. Instead of manually doing this, you can use the AutoArchive feature in Outlook to do the work for you. To activate this feature, right click the folder, click Properties and then click the AutoArchive tab.
