Hi,

I have a problem with safe sender file. I made the gpo for safe sender list (safesender.txt) and it is all working well. Clients get the file and it is appended to their manual entries. The file they get is stored on domain controller, sysvol folder. Trouble starts when i update safesender.txt on domain controller (add more mail addresses), outlook clients don't get updated. It is like outlook is still using first version of safesender.txt. So i tried to make another files, safsender01.txt, changed the GPO to point to new file and guess what, first version (safesender.txt)  is still in use. Is there some safe sender cache in junk filter ? How do i apply changes to clients and why outlook is not accepting this change?

Thank you in advance.
