How do I make Outlook message rules be server based rather than client, so that they will work on web access, Smartphone etc...

Using SBS2003/Exchange 2003/Outlook 2003

By default Outlook/Exchange message rules are applied as server-side rules. They are evaluated even if Outlook is not running.

But there are certain rules that are always client-only – those involving some element from Outlook that does not exist on the Exchange Server.

There is a good article which explains Server-based vs. Client-based rules.

That was the problem - it was looking at recipient address and hence is client side only - cheers! – Jon Rhoades May 26 '09 at 13:46

Another gotcha is that Exchange will process rules server-side until the first client-side rule, so you can mix them, but be careful, some experimentation can often change client-side rules to server-side.

My first rule is to permanently delete "very spammy" mail, but for some reason "permanently delete" is client side, but "move to deleted items" is not.
