Hi I am using Evolution mail client. I could login to exchange server before SSL & FBA authentication was enabled. Thru OWA i am able login using url https://computer-name.domain name/exchange. When i try to login using 'Evolution' mail client, throws error authentication failed for already configured user or unable to connect to server for new mail id configured. I am not sure its evolution problem or i am missing some configuration in client machine. Thanks poornima
