Hello everybody, I have a problem with the new IT structur from my company. We found in the AD2 Mail servers, which is not correct currently. In fact we are talking about mail-01 from the administrative group mail-01, which is correct and uptodate. All our users mailbox are stored there. However before I joined the company, there were another mail server (nt22, administrative group: nt22), which was turned off and deleted, without doing anything in the AD. Now we have problem if we are generating a new mailling list (I dont know the exact name, a group with one email adress and 10 users mailbox, i hope this was understandable), the administrative group is the old one and the current users can not see it. Example: list@domain (several users mail adresse inside) AG is: nt22 and it should be mail-01. Therefore nobody can see them only Domain admins. How can I bring the exchange server to generating the correct administrative group for mailling lists? It should be noted the the AG is correct for new mailboxes for users. Thank you for any answers. gabor
