Is it possible for me as the administrator to set up an Out of Office message on one of my user's accounts, without having to log in as the user and configure it through Outlook?Thanks,Gary

I do not believe this is possible at all on exchange 2003 (maybe a 3rd party tool). Exchange 2007, you could do a hub transport rule, but it'd be more a custom NDR than an OOF.

If you have an account with full admin access, I beleive you can get in to OWA and change it from there. Try your global admin account and log on to where you need to and see if it works.

XTSNJ, I have an admin account, but when I log in to OWA with that, the only options I can find related to Out of Office are for the admin account itself. Please can you advise me more specifically of the method you are proposing? Thanks, Gary

when you login to OWA use the following http://localservername/exchange/useraccount login name you are trying to access so for my account it would be http://server/exchange/xtsnj then use the admin login. try that
