We have added the following lines of coding in our MVC project for open outlook with an attached file.

C#

Outlook.AppointmentItem tempApp =  (Outlook.AppointmentItem)olook.CreateItem(Outlook.OlItemType.olAppointmentItem);
Outlook.Application objApp = new Outlook.Application();
Outlook.MailItem mail = null;
mail = (Outlook.MailItem)objApp.CreateItem(Outlook.OlItemType.olMailItem);
mail.Attachments.Add((object)@"" + FilePath + "", Outlook.OlAttachmentType.olEmbeddeditem, 1, (object)"Attachment");
mail.Display();

it works perfectly by locally,But when it moves to Live server it says the following error

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Please help.
Thanks & Regards,

That simply means that Outlook is not installed on your live server, which is not a bad thing per se.

There's a package that can be deployed to servers allowing applications to access core MAPI objects.

Search for "MAPI CDO" on your favorite search engine, and find the suitable version for your Windows/Exchange.

Good luck.

we have installed Microsoft Exchange Server MAPI Client and Collaboration Data Objects from below link

That didn't help me.Still it shows the same error.

The way you are thinking your process is biased, IMHO. The code you showed is more appropriate for a client machine on which Oulook is installed.
On a server, though, installing an application like Outlook is not recommended. If your goal is only to send emails, then you should use object in System.Net.Mail namespace: it will then rely on core .NET Framework objects rather than on a client application dirtyly installed on a web server.
