Would anyone be able to help me understand why permissions in the security of a Domain user account is being automatically removed after say an hour? Its a Windows SBS 2003 Standard server, and its a 'BESAdmin' user account that 's been added to a SBS user account with SendAs permissions so that it will work with a Blackberry Server installed on the network. I've not been too involved with this until it stopped working so not sure on the full in's and out's but everytime we add this account, its removed about an hour later. We noticed that when this account is added to the SBS user's security group's wth SendAs the Blackberry works, but not without? I've come across this M$ KB Article but dont quite understand it enough?
817433 Delegated permissions are not available and inheritance is automatically disabled
I know of the implications that Exchange SP2 has on the SendAs feature with Blackberry and have following the M$ arctile on this, and the Blackberry KB article on installing hotfix KB895949?
Any help much appreciated!
