Created PST file using Redemption API is empty when loaded in Microsoft Outlook

问题

Environment: I have a windows console application and I am running the exe from command line. Below is my code:

 static void Main(string[] args)
 {
   CreatePSTUsingRedemption(args[0], args[1]);
 }
 private static void CreatePSTUsingRedemption(string messageFilePath, string pstPath)
 {       
   RDOSession pstSession = new RDOSession();
   RDOPstStore store = null;
   store = pstSession.LogonPstStore(pstPath, 1, "combinedPST");
   //actually there is a loop here to loop through each message files.
   RDOMail rdo_Mail = pstSession.GetMessageFromMsgFile(messageFilePath);
   rdo_Mail.CopyTo(store.IPMRootFolder);
   rdo_Mail.Save();
   store.Save();
   completedCount++;
   Console.WriteLine("FILES_PROCESSED:" + completedCount);
   pstSession.Logoff();
 }

Main purpose of this code is to create a single pst file combining email message(.msg) files. Now when I run the exe, a pst file is created in the given location and its size keeps increasing as the code runs. After all the message files are processed application exists. There is no any error. Now, when I try to load this pst file in Outlook 2013. Pst is empty and its size is also reduced to 265KB every time. I don't think any process is using this pst because I can copy and move it anywhere I want. What might be the issue? Any suggestion, please?

UPDATE 1

private static void CreatePSTUsingRedemption(XmlNodeList nodelist, string pstPath)
    {
        System.Diagnostics.Debugger.Launch();
        RDOSession pstSession = null;
        RDOPstStore store = null;
        RDOFolder folder = null;
        RDOMail rdo_Mail = null;
        try
        {
            pstSession = new RDOSession();
            store = pstSession.LogonPstStore(pstPath, 1, Path.GetFileNameWithoutExtension(pstPath));             
            var enumerator = store.IPMRootFolder.Folders.GetEnumerator(); //DELETE DEFAULT FOLDERS
            while (enumerator.MoveNext())
            {
                var defaultFolders = enumerator.Current as RDOFolder;
                    defaultFolders.Delete();
            }
            int completedCount = 0;
            folder = store.IPMRootFolder;
            foreach (XmlNode node in nodelist)
            {
                rdo_Mail = pstSession.GetMessageFromMsgFile(node["FullPath"].InnerText);              
                rdo_Mail.CopyTo(folder);
                rdo_Mail.Save();
                store.Save();
                completedCount++;
                Console.WriteLine("FILES_PROCESSED:" + completedCount);                              
            }            
        }
        finally
        {
            Marshal.ReleaseComObject(rdo_Mail);
            Marshal.ReleaseComObject(folder);
            Marshal.ReleaseComObject(store);
        }
        pstSession.Logoff();
        Marshal.ReleaseComObject(pstSession);
        GC.Collect();
    }

Above is my code for the actual loop. I am loading all the email messages file path from an xml file. I still encounter same issue as above.

回答1:

This is an indication that the PST store is not fully flushed to the disk and Outlook "fixes' the PST file by resetting it.

Try to explicitly release all Redemption objects first before logging off and call GC.Collect(). If you have a loop processing multiple files, release the message on each step of the loop.

 private static void CreatePSTUsingRedemption(string messageFilePath, string pstPath)
 {       
   RDOSession pstSession;
   try
   {
     RDOPstStore store;
     RDOFolder folder;
     RDOMail rdo_Mail;
     pstSession = new RDOSession();
     store = pstSession.LogonPstStore(pstPath, 1, "combinedPST");
     //actually there is a loop here to loop through each message files.
     rdo_Mail = pstSession.GetMessageFromMsgFile(messageFilePath);
     folder = store.IPMRootFolder;
     rdo_Mail.CopyTo(folder);
     rdo_Mail.Save();
     store.Save();
     completedCount++;
     Console.WriteLine("FILES_PROCESSED:" + completedCount);
   }
   finally
   {
     Marshal.ReleaseComObject(rdo_Mail);
     Marshal.ReleaseComObject(folder);
     Marshal.ReleaseComObject(store);
   }
   pstSession.Logoff(); 
   Marshal.ReleaseComObject(pstSession);
   GC.Collect();
 }
