Error Sending Emails with vba

Need a help trouble shooting my outlook vba code process (below)

Before I run this code I create a series of emails using Microsoft Mail merge

I run the process and it creates the emails (may as few as one email or hundreds of emails )

This is done with outlook enterprise offline

I the move the emails to a subfolder of the inbox and run the following code to add attachments and build in a delay if there are a lot of emails to send

At .send the macro stalls and give me an error message "Runtime error '-2147467259 (80004005): This method can't be used with an inline response mail item."

It may not be the cause of your problem but 'maiItem' is not defined which points out that you should always have OPTION EXPLICIT at the top of you code.
