When using the "Send page by email" feature in Internet Explorer for pages within our application that include a Crystal Reports ASP.Net viewer, it drafts the email in Outlook with the web page as an attachment, rather than as the body of the email.
With a previous version of the framework (v1.1), and associated Crystal report viewer, this was not the case. Given those older versions are now unsupported, I'd like to know if there is any way I can "encourage" the "Send page by email" feature of Internet Explorer to send my ASP.Net page as the body instead of as an attachment?
For reference, the source for the viewer is simply:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="GeneralReport.aspx.vb" Inherits="MyApplication.GeneralReportForm"%>
<%@ Register TagPrefix="cr" Namespace="CrystalDecisions.Web" Assembly="CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %>

In the code behind, we simply have:
Dim rpt As New MyReport()
rpt.SetDataSource(ds)
CrystalReportViewer.ReportSource = rpt
CrystalReportViewer.Visible = True

To use this Internet Explorer function go to the web page you want to email, then click on File in the Menu Bar at the top of the Internet Explorer screen, then click on “Send” from the drop down list, and then select “Page by Email” or “Link by Email” from the new list that appears.
However, you can use Internet Explorer if you wish to and if you want to send a page or a link to someone via e-mail from Edge, go to top right corner of the browser, you'll find a share option, just click on that and send the webpage to the desired email address. You can also copy paste the URL as usual.
This may not be a direct answer to your question, but I suggest making your solution not too dependent on a browser feature that may not be or be differently supported in future versions of your preferred browser.
If your web application supports something like a permanent URL for each specific report rendering, an email with the URL as a link should be enough.
Another option would be to render your report as PDF (or XLS) to get a snapshot that can be safely attached to your email.
Still another option is to not depend on the client's browser an email abilities but to send emails by the web application itself through an SMTP server.
Here is an example of how to send an email with an attachment in VB.NET
In case all of the above is not an option to you, in some cases I had success budging IE to change its guess-how-to-handle-page-content behavior by sending an additional http header (as defined in http://www.ietf.org/rfc/rfc2183.txt)
content-disposition: inline versus content-disposition: attachment
Example (C#) to put before final report rendering
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "text/html";
HttpContext.Current.Response.AddHeader("content-disposition", "inline; filename=report.htm");
