外接程序代码可在Outlook 2007和2010中使用，但不能在Outlook 2013中使用

Question

I have an outlook addin code for when user right clicks on any email the addin option shows up in the right click menu. This happens for Outlook 2007 and Outlook 2010 but when I install the addin in Outlook 2013 the option does not show up in the right click menu.

here is my code :

Application.ItemContextMenuDisplay += ApplicationItemContextMenuDisplay; 

void ApplicationItemContextMenuDisplay(Office.CommandBar commandBar, Selection selection)
        {
            var cb = commandBar.Controls.Add(Office.MsoControlType.msoControlButton,missing, missing, missing, true) as Office.CommandBarButton;
            if (cb == null) return;
            cb.Visible = true;
            cb.FaceId = 1675;
            cb.Style = Office.MsoButtonStyle.msoButtonIconAndCaption;                                      
            cb.Click += new Office._CommandBarButtonEvents_ClickEventHandler(_oAddEmail_Click);
            ConvergeCRMSetting settings = StateManager.current.CRMSettings;

            if (selection.Count == 1 && selection[1] is Outlook.MailItem)
            {
                var item = (MailItem)selection[1];                         
                string subject = item.Subject;

                cb.Caption = "Add Email To ConvergeHub";
                cb.Enabled = true;                                        

            }
            else
            {
               cb.Enabled = false;
            }
            bool bflag = false;
            if (settings.Verified == true && settings.Active == true)
            {
                bflag = true;
            }
            switch (Convert.ToInt16(settings.Sd))
            {
                case 0:
                    cb.Enabled = false;
                    break;
                case 1:
                    cb.Enabled = bflag;
                    break;
                case 2:
                    cb.Enabled = bflag;
                    break;
                case 3:
                    //rbManual.Checked = true;
                    break;
                default:
                    break;
            }

        }

What must I do to make the addin option visible in Outlook 2013 ? Any suggestions ?

Answer 1

Command bars have been deprecated - you have to use IRibbonExtensibility to customize context menus for Outlook 2013+:

Answer 2

Eric is right on the depreciation of the command bar since Office 2013. And it has been a good thing I think.

I would recommend to use:

1. the Ribbon designer available with VSTO using Visual Studio. It has a friendly interface to create ribbons instead of command bars. Attaching events works as you are used to from the Windows Forms or WPF designer.

   Useful reading on MSDN here .

2. the Fluent UI and IRibbonExtensibility to bind to context menus, etc.

   Useful reading on MSDN here and here .

Answer 3

You could use an old approach (CommandBars) in Outlook 2007. But starting from Outlook 2010 the Fluent UI is used for customizing context menus in Outlook. You can read more about that in the following articles:

• Customizing Context Menus in Office 2010

• Extending the User Interface in Outlook 2010

The Fluent UI (aka Ribbon UI) is described in the following articles:

• Customizing the 2007 Office Fluent Ribbon for Developers (Part 1 of 3)

• Customizing the 2007 Office Fluent Ribbon for Developers (Part 2 of 3)

• Customizing the 2007 Office Fluent Ribbon for Developers (Part 3 of 3)

The Ribbon designer doesn't provide anything for context menus. You will need to use a ribbon XML markup for customizing context menus.
