I have Exchange 2003sp1 running on Windows 2000 fully patched. Everything is working fine except ActiveSync. I have Check Moble Services properties all looks good here, check potocols,http, Exchange Virtual Server properties of Exadmin, Exchange, and public look fine but Microsoft-server-ActiveSync and OMA properties are grayed out and I cannot change them is this a problem or are the properties grayed out due to configuration effected from another interface. I am not running SSL or Forms based Authentication. When a user tries to sync he gets "your account in Microsoft exchange server does not have permission to synchronize with your current settings. I checked User Account and Active-Sync is enabled. Any Ideas or leads greatly appreciated. Thanks Bruce Rose MCSE2k,CNE6, CCNA,ect Echosat Dir. Engineering. 859-389-8900
