Could not access CDO.Message

[James]

I'm using System.Web.Mail to generate e-mails and I'm adding attachments.
When I add a ~300KB *.doc file, it works as expected. When I attached a 1.2
MB PDF File, I get the following exception:

Any thoughts?

? ex.InnerException

{System.Reflection.TargetInvocationException}

[System.Reflection.TargetInvocationException]:

Is this possibly related to the max size for messages that is set in your
IIS SMTP server?

IIS Admin -> Default SMTP Virtual Server -> Properties -> Message Tab

The default on my Win Xp box is set at 10240K. You are exceeding that.
