We are looking for a method of adding an email address to multiple users' Outlook 2007/2010 (we have a mixed environment) Safe Sender's list without the users having to do anything. Is there a Microsoft approved method of doing this? We have a software distribution tool that we can utilize to copy files, insert registry entries, run scripts, MSIs, EXEs, etc. to accomplish this; we are just missing the file/registry entry/script/MSI/EXE. Any help is appreciated.

Edit: Also, we do not want to overwrite any existing entries that users may have already added to their Safe Sender List.

What type of mail server are you using? Why would you need to do this in the clients? – Zoredache Apr 25 '12 at 7:32
@Zoredache We are using Exchange 2010. I was under the impression this was not something that can be controlled by Exchange and that it was a client setting. Is this not the case? Thanks. – Chck Apr 28 '12 at 19:20

Are you wanting to append? I don't think this is very easy to do ... I think Outlook Profiler has a hidden ini file option, SafeSenders, that can do this ...
