进程陷入oSession.Logoff（）

Question

Pstcreation在安装outlook时正常工作。

现在，我正在尝试使用独立版本的MAPI创建一个pst文件。但我的进程停留在 oSession.LogOff（）。此外，如果注释 oSession.LogOff（）行并随后调用 CreatePstWithRedemption 函数来创建其他pst，则该进程会陷入 oSession.LogonPstStore

private bool CreatePstWithRedemption(EmailJTableArgs objJTablArgs, EmailFilterArgs objFilterArgs,
                                     EmailExportRequestParams emailExportRequestParams)
{
    RDOSession oSession = null;
    IRDOStore store = null;
    RDOFolder fFOlder = null;
    RDOFolder childFolder = null;
    IRDOItems folderItems = null;
    var pstCreationStatus = false;
    try
    {
        oSession = new RDOSession();
        store = oSession.LogonPstStore(_fileName, 1, "PST");

        var folderName = Path.GetFileNameWithoutExtension(_fileName);

        if (store != null)
        {
            fFOlder = store.IPMRootFolder;

            foreach (RDOFolder folder in fFOlder.Folders)
            {
                folder.Delete();
            }
            childFolder = fFOlder.Folders.Add(folderName, Type.Missing);
            folderItems = childFolder.Items;


            var resultOfGetEmails = new ResultGetEmails();
            resultOfGetEmails.TotalCount = -1;

            do
            {
                var journalEmails = GetEmailList(objFilterArgs, objJTablArgs, emailExportRequestParams,
                                                 resultOfGetEmails);
                for (var i = 0; i < journalEmails.Count; i++)
                {
                    IRDOMail mail = null;
                    try
                    {
                        mail = folderItems.Add(rdoItemType.olMailItem);

                        // populate mail fields

                        mail.Sent = true;
                        mail.Save();
                    }
                    finally
                    {
                        if (mail != null)
                            Marshal.ReleaseComObject(mail);
                    }
                }

                resultOfGetEmails.TotalCount -= BatchSize;

                objJTablArgs.PageStartIndex += BatchSize;
            } while (resultOfGetEmails.TotalCount > 0);
            pstCreationStatus = true;
        }
    }

    finally
    {
          // Do cleanup
         if (oSession != null && oSession.LoggedOn)
            {
                try
                {
                    oSession.Logoff();
                    Marshal.ReleaseComObject(oSession);
                }
                catch
                {
                }
            }

    }
    return pstCreationStatus;
}

注意：在安装Outlook的环境中运行时，同样适用。
