When I had this problem, I had to configure in ADUC, for the user with IM enabled, a logon name (since I was migrating, the users had only pre-Windows 2000 logon names). In the MSN Messenger, the e-mail I put was this new_logon_name@domain, where domain is the Windows 2000 domain. -----Mensagem original----- De: Andrea Coppini [mailto:AndreaCoppini@xxxxxxxx] Enviada em: segunda-feira, 26 de agosto de 2002 17:27 Para: [ExchangeList] Assunto: [exchangelist] IM not connecting http://www.MSExchange.org/ Hi gurus, I'm (still) setting up a new Exchange 2k server to migrate our existing 5.5 server. Everything's working fine, BUT IM. I have created (and recreated around 20 times by now) an IM virtual server, installed IM client, checked the DNS entries, etc. as per microsoft step-by-step documentation... I have installed IM client on the Exchange server itself (to avoid routing/port/firewall issues). But I keep getting the 'Sign In To Exchange' dialog box telling me that "The person logged on to this computer does not have permission to use the specified e-mail address. Please type your e-mail address and password" asking me for my E-Mail, Username, Password and Domain. I'm logged in as myself, and I'm a Schema/Domain/Enterprise admin. I'm trying to connect using my own IM account. Any ideas?
