PST/OST file integration with C# Issue

Question

I am using Microsoft.Office.Interop.Outlook Version 12.0.0.0 to read my outlook pst file but when compiler reaches this code outlookNs.AddStore(pstFilePath); it gives exception that “The Outlook data file (.pst) failed to load for this session.” i have triedoutlookNs.AddStoreEx(pstFilePath); also but the error was same ….any sugession ??

 

NOT ABLE TO READ PST/OST FILE THROUGH C# 

 

Here I pass PST File Path & Name 

IEnumerable<MailItem> mailItems = readPst(strSource[0].ToString(), strSource[1].ToString()); 

 

Here is the Method

private static IEnumerable<MailItem> readPst(string pstFilePath, string pstName)

{

List<MailItem> mailItems = new List<MailItem>();

try

{

Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();

NameSpace outlookNs = app.GetNamespace("MAPI");

// Add PST file (Outlook Data File) to Default Profile

outlookNs.AddStore(pstFilePath);

MAPIFolder rootFolder = outlookNs.Stores[pstName].GetRootFolder();

// Traverse through all folders in the PST file

// TODO: This is not recursive, refactor

Folders subFolders = rootFolder.Folders;

foreach (Folder folder in subFolders)

{

if (folder.Name == "Inbox")

{

Items items = folder.Items;

foreach (object item in items)

{

if (item is MailItem)

{

MailItem mailItem = item as MailItem;

mailItems.Add(mailItem);

}

}

}

}

// Remove PST file from Default Profile

//outlookNs.RemoveStore(rootFolder);

progressMaxVal =(int) mailItems.Count;

}

catch (System.Exception ex)

{

}

return mailItems;

}
