Hi everyone, some days ago I install one exchange server 2010 on my new 2008 domain, after some days the exchange server fails and then I had to re-install my exchange from scratch.. i put the same hostname on the server. but the problem now is when on exchange management console I try to re-create the mailbox for one user.. but I can't see all the users I had created mailboxes before, If I create a new user on active directory then i can create the mailbox and works fine, but not with the old users the old server doesn't exist because I reinstall on the same machine. How can I re-create the mailbox on this new server.???

Hi JPCF, Did you un-install exchage without any error, Its look some issue when you removed old server. Looking old exchange attribue still in old AD accounts.
