The following example creates a new Rule and saves it to the messaging server. The rule contains an Actions and Conditions property. The Actions are:

  • The e-mail message is sent to the JunkEmail folder.
  • Assign a category of "Immediate".
  • Assign a category of "Internal use only".

The Conditions are:

  • The e-mail message contains the word "Interesting" in the subject.
// Create an inbox rule.
// If "Interesting" is in the e-mail's subject, move it into the Junk folder
// and assign two categories to the message.
Rule newRule = new Rule();
newRule.Actions.MoveToFolder = WellKnownFolderName.JunkEmail;
newRule.DisplayName = "MoveInterestingToJunk";
newRule.IsEnabled = true;

newRule.Priority = 1; newRule.Actions.AssignCategories.Add("Immediate"); newRule.Actions.AssignCategories.Add("Internal use only.");

// Create the CreateRuleOperation. CreateRuleOperation createRuleOperation = new CreateRuleOperation(newRule); service.UpdateInboxRules(new RuleOperation[] { createRuleOperation }, true);


An Inbox rule is a set of Conditions, Exceptions, and associated Actions that enable clients to automatically organize, categorize, and act on messages as the messages are delivered to a folder. For example, a Rule can be created to require that any incoming mail that contains a certain string in the subject be automatically moved to a predetermined folder. Rule evaluation is triggered when e-mail messages are delivered in a user's mailbox or when messages are first saved to a folder. The Conditions in a Rule are evaluated against the properties of the incoming message. If the Conditions evaluate to true, the rule Actions are executed by the server.
