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.
