Email attachments – An event was unable to invoke any of the subscribers 0x80040201

Table of Contents

Symptom #

When using a variable to save email attachments the following error is produced:

An event was unable to invoke any of the subscribers 0x80040201

Cause #

There are two separate causes:

  1. The attachment file size is zero bytes, this normally indicates a blank file.
  2. The data file variable has not been setup as an Array type.

Resolution #

Make sure that the file attachments from the email are greater than zero bytes.

To store attachments in a variable you a require a ‘data file’ variable which needs to be setup as an Array type. Using array allows a variable to store any number of file attachments from an inbound SMTP email.

The following shows how the variable should be configured:
