Import data (Exchange Distribution list)

Hello,

I have an Exchange 5.5. Server. I want to import data to an Exchange Distribution list.

For example. I created a list called: LIST1. I added 30 mailboxes.

I created a LIST2 and I want to import the users from LIST1 to LIST2.

I clicked on modify option in LIST1 and I noticed that I can select the members of the list and I applied the COPY function.

But when I go to the LIST2 and can not PASTE (for some reason).

Furthermore, I have text files full of mailbox names that Iwant to import.

Thanks in advance.
