赎回的MAPI\ U E\ U FAILONEPROVIDER

cdo.message outlook-redemption exchange-server outlook c#

RossFabricant · 技术社区 · 16 年前

当我以自己的身份登录运行它时,此代码起作用:

public OutlookFolders(string outlookRootFolder, string exchangeUser, string mailServer)
{
    var session = new RDOSessionClass();
    session.LogonExchangeMailbox(exchangeUser, mailServer);
    session.Stores.FindExchangePublicFoldersStore();
    var store = session.GetSharedMailbox(exchangeUser);
    //...
}

我尝试以第三个用户“测试用户”身份登录,该用户不是我,也不是“目标用户”。当我的程序到达FindExchangePublicFoldersStore时,它会在运行时显示一个密码提示,如果我不填写凭据,它将失败,并出现以下错误:

System.Runtime.InteropServices.COMException (0x8004011D): Error in 
    IMAPISession.OpenMsgStore(pbExchangeProviderPrimaryUserGuid):
    MAPI_E_FAILONEPROVIDER

经验法则是以可以访问相关邮箱的用户身份运行代码,请致电LogonExchangeMailbox以获取 现在的 用户,然后使用GetSharedMailbox打开其他用户的邮箱。

它还使用 Milan's blog .

        public OutlookFolders(string exchangeUser, string mailServer)
        {
            var session = new RDOSessionClass();
            var userFullName = GetFullName("DOMAIN-NT\\" + Environment.UserName);
            session.LogonExchangeMailbox(userFullName, mailServer);
            session.Stores.FindExchangePublicFoldersStore();
            var store = session.GetSharedMailbox(exchangeUser);
            rootFolder = store.GetDefaultFolder((rdoDefaultFolders)OlDefaultFolders.olFolderContacts);
        }

        public static string GetFullName(string strLogin)
        {
            string str = "";
            string strDomain;
            string strName;

            // Parse the string to check if domain name is present.
            int idx = strLogin.IndexOf('\\');
            if (idx == -1)
            {
                idx = strLogin.IndexOf('@');
            }

            if (idx != -1)
            {
                strDomain = strLogin.Substring(0, idx);
                strName = strLogin.Substring(idx + 1);
            }
            else
            {
                strDomain = Environment.MachineName;
                strName = strLogin;
            }

            DirectoryEntry obDirEntry = null;
            try
            {
                obDirEntry = new DirectoryEntry("WinNT://" + strDomain + "/" + strName);
                PropertyCollection coll = obDirEntry.Properties;
                object obVal = coll["FullName"].Value;
                str = obVal.ToString();
            }
            catch (System.Exception ex)
            {
                str = ex.Message;
            }
            return str;
        }
