Are you using a self signed cert on the Exchange server, are you connecting with an FQDN that isn't listed on the cert, or is the cert expired?My Book - Active Directory, 4th Edition My Blog - www.briandesmond.com

Thanks Brian, To answer your quesions, Are you using a self signed cert on the Exchange server -- Yes, but i don't know the certificate on exchange server. That was installed by exchange administrator. ( By the by this is test environment for FIM2010 and exhange 2010). Are you connecting with an FQDN that isn't listed on the cert - The certificate SANs are 'mail.domain.net' and 'autodiscover.domain.net" (Installed on FIM server) Is the cert expired - NoTek-Nerd

The cert being self signed is likely your problem. Get a copy of it from your Exchange admin and install it in the trusted root store on your FIM server.My Book - Active Directory, 4th Edition My Blog - www.briandesmond.com
