In the Microsoft Outlook e-mail application, users have the ability to create distribution lists. A distribution list is a group of contacts that can be used to send e-mail messages to multiple people. Distribution list data is stored on your local computer, but you can share the lists you've created with other Outlook users. When you share a distribution list, recipients have the option to save the list on their computer for future use.
Launch Microsoft Outlook on your PC computer.
Click on the "New" button at the top of the screen to open a blank composition window.
Enter the email address of the person with whom you want to share a distribution list in the "To" field.
Press the "Contacts" or "Address Book" button in the top toolbar. This will open a new window with a list of the contacts and distribution lists saved on your computer.
Find the distribution list you want to share and click on the name of it to highlight it.
Drag and drop the highlighted distribution list into the body of the blank e-mail message.
Send the message like you normally would. The receiver will be able to save the distribution list on his or her computer.
