Access users outlook email from IIS application

We have hosted a .net application on our IIS server. This application tries to read the emails from the current logged in users outlook.

I am using the library using Microsoft.Office.Interop.Outlook; and below is my code.

I am able to view the emails when this code runs from my VS. The moment I deploy this application on IIS then I am unable to top read any emails.

This is the error which is logged.

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

Am i following the correct approach on accessing the emails or are there any different ways to archive this? please enlighten.

Below is the whole code.

try
        {

            outlookApplication = new Application();
            outlookNamespace = outlookApplication.GetNamespace("MAPI");
            inboxFolder = outlookNamespace.GetDefaultFolder(OlDefaultFolders.olFolderInbox);
            mailItems = inboxFolder.Items;

            foreach (object item in inboxFolder.Items)
            {

              if (item is Microsoft.Office.Interop.Outlook.MailItem)
                {
                        Microsoft.Office.Interop.Outlook.MailItem mailitem = (Microsoft.Office.Interop.Outlook.MailItem)item;
                        if(mailitem.ReceivedTime.Date ==DateTime.Today)
                        {
                            TempEmail objTempEmail = new TempEmail();
                            objTempEmail.From = mailitem.SenderEmailAddress;
                            objTempEmail.To = mailitem.To;
                            objTempEmail.CC = mailitem.CC;
                            objTempEmail.Subject = mailitem.Subject;
                            objTempEmail.Body = mailitem.Body;

                            lTempEmail.Add(objTempEmail);
                            Marshal.ReleaseComObject(mailitem);
                        }
                }

            }

        }
        catch (System.Exception ex)
        {
            log.Error(ex.Message + "" + ex.InnerException);
        }
        finally
        {
            ReleaseComObject(mailItems);
            ReleaseComObject(inboxFolder);
            ReleaseComObject(outlookNamespace);
            ReleaseComObject(outlookApplication);
        }

"Am i following the correct approach"

No. Outlook interop will only work on the local machine. All you will achieve is checking the AppPool's inbox, which won't exist.
