You can get, create, update, and delete Inbox rules by using the EWS Managed API or EWS. Regardless of the technology you use, you get and modify Inbox rules as a collection, rather than individually. You use the same method or operation to create new rules, update existing rules, and delete rules.

ExchangeService.UpdateInboxRules

UpdateInboxRules

In order to create, update, or delete Inbox rules by using the EWS Managed API or EWS, you must remove the Outlook rule, if it exists. If you’re using the EWS Managed API, you do this by setting the removeOutlookRulesBlob parameter to true in the ExchangeService.UpdateInboxRules method call. If you're using EWS, you set the value of the RemoveOutlookRuleBlob element to true in the UpdateInboxRules operation. We recommend that your application check the RuleCollection.OutlookRuleBlobExists property (if you are using the EWS Managed API), or the OutlookRuleBlobExists element (if you’re using EWS) before updating Inbox rules. If this property or element has a value of true, your application should alert the user that any disabled rules will be lost as part of the update, and only proceed with their permission.

When you call the UpdateInboxRules method, EWS deletes client-side send rules. Client-side send rules are stored on the client in the rule Folder Associated Information (FAI) Message and nowhere else. EWS deletes this rule FAI message by default, based on the expectation that Outlook will recreate it. However, Outlook can't recreate rules that don't also exist as an extended rule, and client-side send rules don't exist as extended rules. As a result, these rules are lost. We suggest you consider this when designing your solution.

Note Note

The EWS Managed API code examples in this article use a common set of utility methods. These methods are omitted from the code samples for brevity.

To get the current Inbox rules, use the ExchangeService.GetInboxRules method. This method returns a RuleCollection object that contains all the current Inbox rules.

In this example, each rule in the current Inbox is passed to a helper function (ParseRuleDetails) to display the details of the rule.

using System;
using System.Collections.Generic;
using Microsoft.Exchange.WebServices.Data;

private static void GetInboxRules(ExchangeService service, string emailAddress)
{
    RuleCollection inboxRules = null;

    Console.WriteLine("Retrieving inbox rules...");
    // Get the rules from the user's Inbox.
    try
    {
        inboxRules = service.GetInboxRules(emailAddress);
    }
    catch (ServiceResponseException ex)
    {
        Console.WriteLine("Error getting inbox rules: {0}", ex.ErrorCode.ToString());
        return;
    }

    // Loop through the rules and print out the details of each.
    foreach (Rule rule in inboxRules)
    {
        Console.WriteLine("\n***************************************************************");
        Console.WriteLine("Rule: {0}", rule.DisplayName);
        Console.WriteLine("Rule ID: {0}", rule.Id);
        Console.WriteLine("Priority: {0}", rule.Priority);
        Console.WriteLine("Enabled: {0}", rule.IsEnabled.ToString());
        Console.WriteLine("Error: {0}", rule.IsInError.ToString());
        Console.WriteLine("Supported: {0}", (!rule.IsNotSupported).ToString());

        ParseRuleDetails(service, rule);
    }
}

The following EWS SOAP request uses the GetInboxRules operation to retrieve the Inbox rules for sadie@contoso.com.

To create a rule, include a CreateRuleOperation object in the collection of RuleOperation objects passed to the ExchangeService.UpdateInboxRules method.

In this example, a new rule is created to move mail sent to a distribution list called "Sales" to a subfolder of the Inbox, also called "Sales".

using System;
using System.Collections.Generic;
using Microsoft.Exchange.WebServices.Data;

private static void CreateInboxRule(ExchangeService service, string emailAddress)
{
    // Before modifying the rules on the server, determine
    // whether an Outlook rules BLOB exists. Updating rules
    // via EWS requires removal of the Outlook BLOB. This can
    // result in any rules that the user has disabled via the Outlook
    // UI to be lost.
    RuleCollection currentRules = null;

    try
    {
        currentRules = service.GetInboxRules(emailAddress);
    }
    catch (ServiceResponseException ex)
    {
        Console.WriteLine("Error getting inbox rules: {0}", ex.ErrorCode.ToString());
    }

    if (currentRules != null && currentRules.OutlookRuleBlobExists)
    {
        Console.WriteLine("WARNING: Adding a new rule will delete the Outlook rule BLOB.");
        Console.WriteLine("This can lead to a loss of any disabled rules.");
        Console.Write("Hit Y to proceed (any other key to cancel): ");
        ConsoleKeyInfo cki = Console.ReadKey();
        if (cki.KeyChar != 'Y' && cki.KeyChar != 'y')
        {
            Console.WriteLine("\nCanceling addition of new rule...");
            return;
        }
        Console.WriteLine();
    }

    Console.WriteLine("Adding \"Sales\" rule.");

    Rule newRule = new Rule();

    // Creating a rule called "Sales"
    newRule.DisplayName = "Sales";

    // Conditions
    // When messages are sent to the "Sales" address (sales@contoso.com),
    newRule.Conditions.SentToAddresses.Add("Sales", "sales@contoso.com");

    FolderId moveToFolderId = GetFolderIdByName(service, WellKnownFolderName.Inbox, "Sales");
    if (moveToFolderId == null)
    {
        throw new ArgumentException("Invalid subfolder specified");
    }

    // Actions
    // Move the message to the "Sales" folder
    newRule.Actions.MoveToFolder = moveToFolderId;
    // And stop processing more rules
    newRule.Actions.StopProcessingRules = true;

    // Exceptions
    // Except if the message is from Hope Gross (hope@contoso.com).
    newRule.Exceptions.FromAddresses.Add("Hope Gross", "hope@contoso.com");

    Console.WriteLine("Rule: {0}", newRule.DisplayName);
    ParseRuleDetails(service, newRule);

    // Add the new rule to the CreateRule operation.
    CreateRuleOperation createMoveIfFromSalesRule = new CreateRuleOperation(newRule);

    try
    {
        // Update rules. Note that this method can accept
        // an array of rule operations, enabling you to batch
        // updates.
        service.UpdateInboxRules(new RuleOperation[] { createMoveIfFromSalesRule }, true);
    }
    catch (UpdateInboxRulesException ex)
    {
        Console.WriteLine("Error updating Inbox rules: {0}", ex.ErrorCode.ToString());
        return;
    }

    Console.WriteLine("Rule added.");
}

The following EWS SOAP request creates the "Sales" rule in sadie@contoso.com's Inbox.

To update a rule, include a SetRuleOperation object in the collection of RuleOperation objects passed to the UpdateInboxRules method.

In this example, the "Sales" rule is updated to add an exception. If the subject contains the word "Urgent", the messages will not be moved to the "Sales" subfolder.

using System;
using System.Collections.Generic;
using Microsoft.Exchange.WebServices.Data;

private static void UpdateInboxRule(ExchangeService service, string emailAddress)
{
    // Before modifying the rules on the server, determine
    // whether an Outlook rules BLOB exists. Updating rules
    // via EWS requires removal of the Outlook BLOB. This can
    // result in any rules that the user has disabled via the Outlook
    // UI to be lost.
    RuleCollection currentRules = null;

    try
    {
        currentRules = service.GetInboxRules(emailAddress);
    }
    catch (ServiceResponseException ex)
    {
        Console.WriteLine("Error getting inbox rules: {0}", ex.ErrorCode.ToString());
    }

    if (currentRules != null && currentRules.OutlookRuleBlobExists)
    {
        Console.WriteLine("WARNING: Updating an existing rule will delete the Outlook rule BLOB.");
        Console.WriteLine("This can lead to a loss of any disabled rules.");
        Console.Write("Hit Y to proceed (any other key to cancel): ");
        ConsoleKeyInfo cki = Console.ReadKey();
        if (cki.KeyChar != 'Y' && cki.KeyChar != 'y')
        {
            Console.WriteLine("\nCanceling update of rule...");
            return;
        }
        Console.WriteLine();
    }

    // Look for the rule called "Sales" and modify it
    // to add an exception if "Urgent" is in the subject.
    Console.WriteLine("Updating rule \"Sales\"...");
    Rule ruleToUpdate = null;

    foreach (Rule rule in currentRules)
    {
        if (rule.DisplayName == "Sales")
        {
            ruleToUpdate = rule;
            break;
        }
    }

    if (ruleToUpdate == null)
    {
        Console.WriteLine("Could not find a rule called \"Sales\", canceling update.");
        return;
    }

    // Add the exception.
    ruleToUpdate.Exceptions.ContainsSubjectStrings.Add("Urgent");

    SetRuleOperation setRuleOperation = new SetRuleOperation(ruleToUpdate);

    try
    {
        // Update rules. Note that this method can accept
        // an array of rule operations, enabling you to batch
        // updates.
        service.UpdateInboxRules(new RuleOperation[] { setRuleOperation }, true);
    }
    catch (UpdateInboxRulesException ex)
    {
        Console.WriteLine("Error updating Inbox rules: {0}", ex.ErrorCode.ToString());
        return;
    }

    Console.WriteLine("Rule updated.");
}

The following EWS SOAP request updates the "Sales" rule in sadie@contoso.com's Inbox.

To delete a rule, include a DeleteRuleOperation object in the collection of RuleOperation objects passed to the UpdateInboxRules method.

In this example, the "Sales" rule is deleted.

using System;
using System.Collections.Generic;
using Microsoft.Exchange.WebServices.Data;

            return;
        }
        Console.WriteLine();
    }

    // Look for the rule called "Sales" and delete it.
    Console.WriteLine("Deleting rule \"Sales\"...");
    string ruleId = string.Empty;

    foreach (Rule rule in currentRules)
    {
        if (rule.DisplayName == "Sales")
        {
            ruleId = rule.Id;
            break;
        }
    }

    if (string.IsNullOrEmpty(ruleId))
    {
        Console.WriteLine("Could not find a rule called \"Sales\", canceling delete.");
        return;
    }

    DeleteRuleOperation deleteRuleOperation = new DeleteRuleOperation(ruleId);

    catch (UpdateInboxRulesException ex)
    {
        Console.WriteLine("Error updating Inbox rules: {0}", ex.ErrorCode.ToString());
        return;
    }

    Console.WriteLine("Rule deleted.");
}

The following EWS SOAP request deletes the "Sales" rules from sadie@contoso.com's inbox.
