Get Outlook email address through c#

Question

I need to be able to get the currently logged in user's email address with C# code.

I need the full address and not just the assumed email account (eg [email protected]), although this will work for most clients.

Any help will be greatly appreciated.

Try this, from http://msdn.microsoft.com/en-us/library/ff462091.aspx:

using System;
using System.Text;
using Outlook = Microsoft.Office.Interop.Outlook;

namespace OutlookAddIn1
{
    class Sample
    {
        public static void DisplayAccountInformation(Outlook.Application application)
        {

            // The Namespace Object (Session) has a collection of accounts.
            Outlook.Accounts accounts = application.Session.Accounts;

            // Concatenate a message with information about all accounts.
            StringBuilder builder = new StringBuilder();

            // Loop over all accounts and print detail account information.
            // All properties of the Account object are read-only.
            foreach (Outlook.Account account in accounts)
            {

                // The DisplayName property represents the friendly name of the account.
                builder.AppendFormat("DisplayName: {0}\n", account.DisplayName);

                // The UserName property provides an account-based context to determine identity.
                builder.AppendFormat("UserName: {0}\n", account.UserName);

                // The SmtpAddress property provides the SMTP address for the account.
                builder.AppendFormat("SmtpAddress: {0}\n", account.SmtpAddress);

                // The AccountType property indicates the type of the account.
                builder.Append("AccountType: ");
                switch (account.AccountType)
                {

                    case Outlook.OlAccountType.olExchange:
                        builder.AppendLine("Exchange");
                        break;

                    case Outlook.OlAccountType.olHttp:
                        builder.AppendLine("Http");
                        break;

                    case Outlook.OlAccountType.olImap:
                        builder.AppendLine("Imap");
                        break;

                    case Outlook.OlAccountType.olOtherAccount:
                        builder.AppendLine("Other");
                        break;

                    case Outlook.OlAccountType.olPop3:
                        builder.AppendLine("Pop3");
                        break;
                }

                builder.AppendLine();
            }

            // Display the account information.
            System.Windows.Forms.MessageBox.Show(builder.ToString());
        }
    }
}

Get email id from outlook

createdby = mailItem.UserProperties.Session.CurrentUser.Address;

or, we can use this

if (app.Session.CurrentUser.AddressEntry.Type == "EX") {
    createdby = app.Session.CurrentUser.AddressEntry.GetExchangeUser().PrimarySmtpAddress;
} else {
    createdby = app.Session.CurrentUser.AddressEntry.Address;
}
