Images in the email signature are shown as attachments on the received message

Scenario:

You use Exclaimer Signature Manager Exchange Edition, or Exclaimer Mail Disclaimers as follows:

  • In Exclaimer Signature Manager Exchange Edition, or Exclaimer Mail Disclaimers, you have configured a signature policy to append an email signature that contains embedded images
  • You have a Microsoft Exchange transport rule to append disclaimers to messages

When sending a message that has a signature policy (for a signature) and the transport rule (for a disclaimer) applied to it, images in the email signature are displayed as attachments on the received message. In addition, image placeholders (with a red x) are displayed in the message body, where the images should be.

Solution:

Disable the Microsoft Exchange Transport rule and use a signature policy (in Exclaimer Signature Manager Exchange Edition, or Exclaimer Mail Disclaimers) to append the signature AND disclaimer to the message instead (signature policies can be used to apply disclaimer content, as well as signature content. You can also apply more than one policy to an email).
