I have a laptop which is connected to our company wireless network. Unlike the other laptops it is not a member of the AD domain.
When I try to create an exchange account in outlook 2007 and enter the Exchange Server name or IP Address I get an error "The connection to Microsoft Exchange is unavailable" and the username check fails.
The strange thing is that if I enter the IP address of the DNS server, not the Mail Server, the username check works and the username and mail server names are underlines. It replaced the DNS server IP with the mail server name.
but I still can't access the exchange server.
I have checked DNS and the DNS setting on the laptop and they appear ok.
This problem has only occurred since we moved from Exchange 2003 SBS to 2013. Its like an old exchange record is in DNS or Active directory??
