Add Ribbon Control In Outlook 2013 Using Outlook 2013 Add-in In Visual Studio

Here I am describing how to add ribbon control inside Outlook mail.

Step 1: Open Visual Studio 2013 and then click on Office Add-ins. After that click Outlook 2013 Add-in.



Step 2: Go to solution explorer and right click then add new items and new ribbon (XML).



Step 3: Then write the same code inside XML file.

<ribbon>
    <tabs>
        <tab id="TabAddIns" label="My Ribbon">
            <group id="Group1" label="Ribbon Options">
                <button id="btnSettings" onAction="btnSettings_Click" imageMso="AdministrationHome" label="Settings" size="normal" />
                <button id="btnHelp" onAction="btnHelp_Click" imageMso="Help" label="Get Help and Support" size="normal" /> </group>
            <group id="Group2">
                <button id="BtnMy" imageMso="HappyFace" onAction="BtnMy_Click" label="My Button" size="large" /> </group>
        </tab>
        <tab id="TabAddIns1" label="My Ribbon1">
            <group id="Group11" label="Ribbon Options1">
                <button id="btnSettings1" onAction="btnSettings_Click" imageMso="AdministrationHome" label="Settings" size="normal" />
                <button id="btnHelp1" onAction="btnHelp_Click" imageMso="Help" label="Get Help and Support" size="normal" /> </group>
        </tab>
    </tabs>
</ribbon>

Step 4: Then go to ribbon.cs file and write the same code.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;
using Office = Microsoft.Office.Core;
// TODO: Follow these steps to enable the Ribbon (XML) item:
// 1: Copy the following code block into the ThisAddin, ThisWorkbook, or ThisDocument class.
// protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
// {
// return new MyRibbon();
// }
// 2. Create callback methods in the "Ribbon Callbacks" region of this class to handle user
// actions, such as clicking a button. Note: if you have exported this Ribbon from the Ribbon designer,
// move your code from the event handlers to the callback methods and modify the code to work with the
// Ribbon extensibility (RibbonX) programming model.
// 3. Assign attributes to the control tags in the Ribbon XML file to identify the appropriate callback methods in your code.
// For more information, see the Ribbon XML documentation in the Visual Studio Tools for Office Help.
namespace OutlookAddIn2
{
    [ComVisible(true)]
    public class MyRibbon: Office.IRibbonExtensibility
    {
        private Office.IRibbonUI ribbon;
        public MyRibbon()
        {}
        public void btnSettings_Click(Office.IRibbonControl control)
        {
            MessageBox.Show("Settings ");
        }
        public void BtnMy_Click(Office.IRibbonControl control)
        {
            MessageBox.Show("MyButton ");
        }
        public void btnHelp_Click(Office.IRibbonControl control)
        {
            MessageBox.Show("Help ");
        }#region IRibbonExtensibility Members
        public string GetCustomUI(string ribbonID)
        {
            return GetResourceText("OutlookAddIn2.MyRibbon.xml");
        }#endregion# region Ribbon Callbacks
        //Create callback methods here. For more information about adding callback methods, visit http://go.microsoft.com/fwlink/?LinkID=271226
        public void Ribbon_Load(Office.IRibbonUI ribbonUI)
        {
            this.ribbon = ribbonUI;
        }#endregion# region Helpers
        private static string GetResourceText(string resourceName)
        {
            Assembly asm = Assembly.GetExecutingAssembly();
            string[] resourceNames = asm.GetManifestResourceNames();
            for (int i = 0; i < resourceNames.Length; ++i)
            {
                if (string.Compare(resourceName, resourceNames[i], StringComparison.OrdinalIgnoreCase) == 0)
                {
                    using(StreamReader resourceReader = new StreamReader(asm.GetManifestResourceStream(resourceNames[i])))
                    {
                        if (resourceReader != null)
                        {
                            return resourceReader.ReadToEnd();
                        }
                    }
                }
            }
            return null;
        }#endregion
    }
}

Step 5: Then build it and run the application.

After that all custom ribbon will be shown on top of the outlook mailbox.



Here I have described each line of the code plus posted all screenshots.

Please go through that and develop on your own.
