Cannot open saved zip files extracted from Outlook Mail

Hi Everyone,
I've created a small C# application which extracts attachments from outlook emails and saves them to a network location. I can open all of the saved files except for compressed files with "zip" extension.
Files with the "zip" extension can only be opened/extracted via Windows Explorer. If I try to use WinRAR, I get the following error: "The archive is either in unknown format or damaged". WinZip does not work either. If however, I open the email within outlook manually and copy the zip file to my PC, I am able to open the zipped file using WinRAR, WinZip as well as windows explorer.
Part of the code used to save the attachment is shown below.
Microsoft.Office.Interop.Outlook.MailItem _mailItem;
...
...
_AttachFileName = _mailItem.Attachments[j].FileName;
_TempAttachmentFile = Path.Combine(_tempFolder.Path, _AttachFileName);
_mailItem.Attachments[j].SaveAsFile(_TempAttachmentFile);
...
...
Has anyone faced a similar issue with compressed zip files? If so were you able to resolve the issue?
Any ideas or help on this will be appreciated.
Thanks
Navnit
