Hi, You need to have SP1 fully installed before you start troubleshooting OWA. Did you do what the error message told you to: Error read: When the Authmechanism parameter on a receive connector is set to the valueExchange server, you must set the FQDN paramter on the receive connector to one of the following values: FQDN of the transport server:"grkms1.gorkana.local",the netbios nameof the transport server "grkms1", or $null.

Hi Leif,I am just to afraid to install it again.I did get the error started above but i simply don't know what to do from therePlease help. What should i do i simply don't know. I can't start the IMAP4 and POP3 services anymore please help.RegardsBK

You right i installed SP1 again in full and it solve the whole issue. I need to change the domain as suggested. on server configuration---hub transport---default and that change to the suggested. Also i think some services need to be stopped like most exchange and www. services during the installation. If you need help contact kebbay.brahim@gmail.com

I have this same issue, however when i try to run the setup again I get "Exchange Server setup encountered an error".I have downloaded the SP1....Any way to get around this?
