Thank you all for repling, I appreciate all your input. I finally got my new machine (Dell Precision M70 - very nice) and am now working hard on getting Evolution to talk to my Exchange 2K server. I have search this list and host found mixed results on whether the latest Evolution will talk to Exchange reliable. I currently have the following installed: # rpm -q -a | grep evolution evolution-webcal-2.2.0-1 evolution-data-server-1.2.2-2 evolution-connector-2.2.0-1 evolution-2.2.2-1 Based on the following Windows Login: login_name Windows Domain: domain Email Address on Exchange server: First_Last Fill Email Address: <a href="mailto:First_Last@mycompany.com">First_Last@mycompany.com</a> OWA server URL: <a href="https://myexchange-server.mycomany.com/exchange">https://myexchange-server.mycomany.com/exchange</a> What do I put into Evolutions text boxes? What I have below is failing: Identity Window: Full Name: First Last Email Address: <a href="mailto:First_Last@mycompany.com">First_Last@mycompany.com</a> Recieving Email: Server Type: Microsoft Exchange Username: domain\login_name OWA Url: <a href="https://myexchange-server.mycomany.com/exchange">https://myexchange-server.mycomany.com/exchange</a> When I press "Authenticate" the first time the window will prompt "Enter password for domain\login_name". At this point the authentication window goes away however the "Forward" buttom is still grayed out - no error message When I press "Authenticate" a second time the window will prompt "Enter password for First_Last". After typing my password again I get an error window that reads Could not authenticate to the Exchange server. Make sure the username and password are correct and try again. You may need to specify the Windows domain name as part of your username (eg, "MY-DOMAIN\First_Last"). I'm not sure what to do. If any one can point me in the right direction or give me some advice I would greatly appreciate it. Thank you very much
