I have successfully used CDO mail methods and had to have our System Administator install the CDONTS.dll file on the IIS server using the IMS wizard.<BR>...now I want to use the MAPI mail method. I ran a test and got this error when I tried to create the object.<BR><BR>Server object error &#039;ASP 0177 : 800401f3&#039; <BR><BR>Server.CreateObject Failed <BR><BR>/GPDataClear/Beta/EmailSend.asp, line 20 <BR><BR>Invalid class string <BR><BR> What file/s need to be installed on the server for this to function? and how do we install this file/s?<BR><BR>Jose
