unable to connect outlook to our exchange
Posted on 2010-11-29
Our current environment is exchange 2007; we have just installed exchange 2010 to coexist in the same domain to we can upgrade.
OWA works find on the exchange 2010 box and 2007. I am able to create users in 2010. And use OWA to send emails from it. But I am unable to connect outlook to our 2010 box.. I get an error message, "outlook could not be log on. Check and make sure your are connected to the network" I can ping my exchange 2010 box by name and IP.
Also when i tried to telnet, i was able to get through but when i do the command
i get 5.7.1 client was not authenticated. But this user is able to log on to the 2010 owa and send out emails fine.
I am not sure what I’m missing can anyone please point me in the right direction
thank you very much
