Hi,

What the best was to create 100 New Exchange 2010 Mailboxes and Active Directory User Accounts.

Fields as follow:-

1 Firstname
2 Lastname
3 Mailbox Alias - firstname.lastname
4 Email Alias :- firstname.lastname@xxx.whatever
5 AD Account :- firstname.lastname
6 AD OU :- XXX.local/useraccounts
7 Password :- Xxxxx1234!   (Same password for all accounts.)


Thanks in advance !!
