MORE INFORMATION

This is by product design.

Steps to Reproduce the Behavior

For a Personal Distribution List:

1. Create three mailboxes in Exchange Administrator (user1,user2, user3).
2. Create a distribution list called All in Exchange Administrator.
3. From a client computer (the operating system doesn't matter), set up a profile for user1 and log on to the mailbox.
4. Open Notepad and type "user1, user2, user3" (one entry on each line).
5. Select all three users in Notepad and copy the text to the Clipboard by pressing CTRL+C.
6. Create a distribution list by using these steps.
   
   
   1. Open Address Book.
   2. On the File menu, click New Entry, or click the New Entry button.
   3. Select personal Distribution List.
   4. Click Add/Remove Members.
   5. In the Members list, press CTRL+V to paste the user names.
7. Click OK.
8. In the Show Names From The list box, select the Personal Distribution List.

Notice the Personal Distribution List has been created with all three members.

Try these same steps for a Global Distribution List:

1. Open the Address Book from the client.
2. In the Show Names From The list box, select Global Address List. Double-click the All Distribution List.
3. In the Members box, choose Modify.
4. Click Add.
5. Try to paste the same three users into the Add Users text box (to the right of the Add button) as was done with the Personal Distribution List. Note that nothing is pasted.
