Error: Could not access CDO.Message object

 

Question:

I'm getting Could not access 'CDO.Message' object error when email to user or admin is sent.

Answer:

This error message is quite generic. Here are some suggestions on fixing this:

Suggestion 1

Specify a valid SMTP server in ASPRunner. If that property is not set, at least set it to 127.0.0.1 or to localhost.

Suggestion 2

If you are using "localhost" or "127.0.0.1" as SMTP server, you may not have permissions to relay through the IIS SMTP Service. To allow access, open up the IIS Admin MMC. Locate the SMTP Virtual Server, and right-click, then select Properties. On the Access tab, click the Relay button. In the Relay Restrictions dialog, grant your IP address (127.0.0.1) to the Computers listbox. Close down all dialogs, and restart the SMTP Service.

Suggestion 3

If you are using "localhost" or "127.0.0.1" as the SMTP server, make sure Anonymous access is allowed. To allow access, open up the IIS Admin MMC. Locate the SMTP Virtual Server, and right-click, then select Properties. On the Access tab, click the Authentication button. Be sure "Anonymous Access" is the only checkbox checked. Close down all dialogs, and restart the SMTP Service.

Suggestion 4

The email address does not have a valid TO address. No spaces in email address.

Suggestion 5

Use a real FROM address that exists on the SmtpMail.SmtpServer. Do not use something like "asdf@asdf.com", or some other bogus address as your FROM. Some mail servers will catch this, and will deny relaying.
