You can generate a .csv file containing a list of mailbox identities from the source forest. Then, you can pipe the content of this file into the script to bulk-create the target mail-enabled users.

For example, the content of the .csv file can be:

Identity

Ian@contoso.com

John@contoso.com

Cindy@contoso.com
