I need to setup a custom Outlook 2007 rule and push it to a system(s) without user interaction. I do NOT have access to the Exchange server. How would I do this? Reg key?
Outlook rules used to be housed on the client running Outlook in earlier versions of Outlook in a file known as a .rwz file. As of Outlook 2007 these are no longer used as they are now stored on the server instead. However the only way I know of would require the user to do an import of the .rwz file, which then copies the settings up to the server. So to answer without interaction there is no way of doing this that I know of.
The .RWZ file would indeed exist if it was migrated from another machine or the software was upgraded from another version of Outlook.
As far as getting it to another machine that could be done a myriad of ways, but would still require user intervention to import the .rwz
Outlook web access (webmail) will allow you to login as that user and set up a rule on the Exchange server. :)
