Error when sending email via outlook, Does this require a server application?

Requirement: My application has a requirement to send emails via outlook. I could accomplish this using Outlook = Microsoft.Office.Interop.Outlook;

The application works fine on development environment but iam getting an exception: System.Runtime.InteropServices.COMException (0x80040154): 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))

I do not have outlook installed on an application server. Do I need to install outlook on a server? or the exception is for some other reason? how to get rid of it?

The CLSID for Outlook is {0006F03A-0000-0000-C000-000000000046}. As the error code suggest, it cannot find the Class. You will need to install Outlook (the same version on you have on the development should be also installed on the application server).

(ps - please tick if i am correct, thank you!)
