Outlook VSTO 加载项：未应用 AutoFormatRule 筛选器

Question

我正在尝试以编程方式将自动格式规则应用于 Outlook 2016。首先，我手动创建了一个规则并读取过滤器属性，我有这样的过滤器：

"(\"urn:schemas:httpmail:read\" = 0 AND \"http://schemas.microsoft.com/mapi/proptag/0x001a001e\" = 'IPM.Note.MyMessage')"

然后我尝试以编程方式应用它：

Dictionary<string, OlColor> colorizationRules = new Dictionary<string, OlColor>()
        {
            {Resources.MsgClass1, OlColor.olColorRed},
            {Resources.MsgClass2, OlColor.olColorYellow},
            {Resources.MsgClass3, OlColor.olColorGreen}
        };

        Explorer explorer = Application.ActiveExplorer();

        if (explorer != null)
        {
            TableView tableView = explorer.CurrentView as TableView;

            if (tableView != null)
            {
                IEnumerable<AutoFormatRule> rules = tableView.AutoFormatRules.Cast<AutoFormatRule>();

                foreach (KeyValuePair<string, OlColor> coloriztionRule in colorizationRules)
                {                       
                    AutoFormatRule newRule = tableView.AutoFormatRules.Add(coloriztionRule.Key);

                    newRule.Filter = $"(\"urn:schemas:httpmail:read\"=0 AND \"http://schemas.microsoft.com/mapi/proptag/0x001a001e\"='{coloriztionRule.Key}')";
                    newRule.Font.Color = coloriztionRule.Value;
                    newRule.Enabled = true;

                    tableView.AutoFormatRules.Save();
                    tableView.Save();
                    tableView.Apply();
                }
            }
        }

已创建规则，但未应用过滤器值。

其中一个建议是过滤器值必须以“@SQL=...”为前缀。但那是行不通的。

然后我找到了这个话题Outlook 2010 AutoFormatRule.Filter property not saving

响应是：

I raised a premier call in response to this issue. The response was that it is a known bug in the Outlook Object Model. It will not be fixed in Outlook 2010 or Outlook 2013 as the risk is too great for the small change.

建议的解决方法是：

The workaround solution that Microsoft provided was to copy a rule from a Public Folder to the user's profile.

这是什么意思？是否有任何其他解决方法可以使规则在 C# 代码中起作用？

Answer 1

这是 Outlook 中的一个错误，MS 不打算修复它。

Answer 2

这个问题是有解决办法的，虽然有点乱。这绝对是一个 Outlook 错误，导致以编程方式创建的 AutoFormatRules（通过 Outlook UI 查看条件格式）在半损坏状态下创建，不会持续更改视图或重新加载应用程序。您可以通过向 Explorer.ViewSwitch 事件添加事件处理程序来解决此问题，该事件会在每次更改视图时删除并重新创建 AutoFormatRule。这将使您的条件格式规则看起来好像工作正常。

我们已使用此技术实现条件格式设置，通过具有基于邮件项目的 crmLinkState 自定义属性值的条件格式设置规则，突出显示待跟踪到 Dynamics CRM 的电子邮件。

    public partial class BrethertonsAddIn
    {
        Outlook.Explorer _activeExplorer;

        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            _activeExplorer = this.Application.ActiveExplorer();
            _activeExplorer.ViewSwitch += BrethertonsAddIn_ViewSwitch;
            BrethertonsAddIn_ViewSwitch();
        }

        private void BrethertonsAddIn_ViewSwitch()
        {
            Outlook.Explorer olExplorer = Application.ActiveExplorer();
            // Convert the Outlook view into a COM _TableView class which as the AutoFormatRules exposed as properties
            // return if this cast cannot be done
            Outlook._TableView tv = olExplorer.CurrentView as Outlook._TableView;
            if (tv == null) return;
            // Try to find an existing AutoFormatRule for CRM Tracking and delete it
            // Use of the loop is necessary as there is no delete method on the AutoFormatRule object
            // So it's necessary to use the Remove method of a collection object instead
            for (int n = tv.AutoFormatRules.Count; n > 1; n--)
            {
                if (tv.AutoFormatRules[n].Name == "CRM Tracking Pending")
                {
                    tv.AutoFormatRules.Remove(n);
                }
            }
            //Add a new rule and then configure it
            Outlook.AutoFormatRule afr = tv.AutoFormatRules.Add("CRM Tracking Pending");
            afr.Filter = "\"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/crmLinkState\" = 1";
            afr.Font.Italic = true;
            afr.Font.Bold = true;
            afr.Font.Color = Outlook.OlColor.olColorGreen;
            afr.Enabled = true;
            // Save and apply the changes to the rule
            tv.Save();
            afr.Filter = "\"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/crmLinkState\" = 1";
            tv.Apply();
            afr.Filter = "\"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/crmLinkState\" = 1";
        }
}
