Corrupt PST files


We are using the Aspose.Email product for .Net to create PST files and insert MSG files into them. This is the code we are using:

private List WriteToFolder(List mapiMessageItems, string folderPath, string pathToPstFile)
PersonalStorage _personalStorage = PersonalStorage.Create(pathToPstFile, FileFormatVersion.Unicode);
if (string.IsNullOrEmpty(folderPath))
return _personalStorage.RootFolder;

string[] folders = folderPath.Split(new[] { Path.DirectorySeparatorChar }, StringSplitOptions.RemoveEmptyEntries);
FolderInfo folderInfo = null;
FolderInfo parentFolder = _personalStorage.RootFolder;
for (int i = 0; i < folders.Length; i++)
string fldName = folders[i];

var existsFolder = parentFolder.GetSubFolder(fldName);
if (existsFolder == null)
FolderInfo folderInfo = null;
string key = StandardIpmFolders.Keys.FirstOrDefault(x => string.Compare(x, fldName, StringComparison.OrdinalIgnoreCase) == 0);
if (!string.IsNullOrEmpty(key) && currentFolder == _personalStorage.RootFolder)
folderInfo = _personalStorage.CreatePredefinedFolder(fldName, StandardIpmFolders[key]);
else if (currentFolder != null)
folderInfo = currentFolder.AddSubFolder(fldName);
parentFolder = folderInfo;
parentFolder = existsFolder;
if (i == folders.Length - 1 && folderInfo == null)
folderInfo = parentFolder;
IEnumerable mapiMessages = mapiMessageItems.Select(i => i.Message).ToList();
return mapiMessageItems;
catch (Exception ex)
Logger.Error("Failed to add multiple items to PST! Exception: " + ex);

//-----------------Class MapiMessageItem has the following public properties---------------------//

public class MapiMessageItem : Item
/// Message content
public MapiMessage Message { get; set; }

/// Used for Envelope reconstructor and verification (only P2 should be verified)
public MapiMessage P2 { get; set; }

The created PST file can be opened in Outlook 2010/2013/2016 and I can see and open all emails but when I check the PST file with the tool “scanpst.exe” which is part of the Outlook installation I get the message that there are errors in the PST. This is the output of “scanpst.exe”:

We are sending these PST files to another vendor for ingestion, and their ingestion tool is failing to ingest most of these files. Our project is in a seriously bad situation, so i request that this be prioritized and resolved as quickly as possible.

We have been able to reproduce this issue with the last three releases of Aspose.Email, including 6.2.

Please advise.
