CDO.Message.1 error '80070005' Access is denied. - iis-7

Question

I am getting this error when I try to send via the local server
CDO.Message.1 error '80070005'
Access is denied.
/mail.asp, line xxx
Here is the code I am using
MailBodyText = "TEST"
Set objNewMail = CreateObject("CDO.Message")
objNewMail.To = sSendTo
objNewMail.From = "webmaster#EXAMPLE.com"
objNewMail.Cc = "webmaster#EXAMPLE.com"
objNewMail.Subject = "Information Request & Feedback"
objNewMail.HTMLBody = "The following information was sent from " & sEmail & ":" & "<br>" & CHR(13) & MailBodyText & "<br>copies of this mail we sent to :"& sSendTo
objNewMail.Send
Set objNewMail = Nothing
It looks like it is a permission error at the ISSUR doesn't have write permission to write to the mailroot/pickup folder.
But we have checked that and the services account that this site is using seems to have the rights.
Question is this error always a file permission error?
Question how to know / set the location that CDO is using? So we can confirm the permissions
What else should look at to fix this?

Answer 1

Use the .configuration property which allows for authentication and other fine tuning..
examples at : http://www.paulsadowski.com/wsh/cdo.htm
update
The .configuration property allows to set the pickup directory (as you request)
objNewMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 1
objNewMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory") = "c:\inetpub\mailroot\pickup"
objNewMail.Configuration.Fields.Update
objNewMail.Send

Answer 2

IF YOU DON'T WANT TO CHANGE YOUR CODE
Grant IIS_IUSRS group write access to c:\inetpub\mailroot\Pickup folder or whatever is your pickup dir.
It must be IIS_IUSRS Group, not the IUSR User (you got it mispelled probably).
I was getting this error after performing steps specified in option 3 at blog.msdn.com
I didn't have to change the ASP code. Your code works fine on my server.

Answer 3

I am migrating some old classic asp sites to a new (windows 2008R2) server and I had "exactly" the same problem (well at least the same error and basically the same code). The solution presented by Gaby:
objNewMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 1
objNewMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory") = "c:\inetpub\mailroot\pickup"
did not work for me, i still had the same error.
After some searching i found this suggestion:
myMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
myMail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "localhost"
(do NOT set the smtpserverpickupdirectory)
Now it works fine.
By the way if you need to set up the necessary SMTP service on Windows 2008 server (IIS7), I found this blog extremely helpfull.
UPDATE:
According to microsoft sendusing = 1 uses the SMTP server and sendusing 2 uses Outlook Express, I've looked on the server, and there doesn't seem to be outlookexpress or windows mail installed, still this setting workes for me. If anyone could explain that I'm curious to know.
