I used below Microsoft link to configure Safe sender list for Outlook 2007 http://support.microsoft.com/default.aspx?scid=kb;EN-US;2252421 But after that I have problem in some users Safe sender list did not show in Outlook web Access. But it shows in outlook Client. After that client domain message which is in Safe sender domain are shows in Junk folder. I try some setting if I change manually safe sender list in outlook client than it shows all safe sender domain list in OWA as well. Is there any Update I am missing or some setting in client or server side Thanks in AdvanceManish Sain
