Scenario
Occasionally, you notice that images in your signatures and/or message body are misplaced - for example, spurious resizing or a previously embedded image replaces the correct image.
Reason
There are two possible reasons for this behaviour, as summarized below:
-
Original image name clashes with an Outlook generated name
At the time of creating a signature template, you used a simple image name; for example, image001.png. By default, Outlook changes the names of embedded images into the format: image001@someID, image002@someID and so on. If the name of your image happens to match the one generated by Outlook, the images are swapped and displayed incorrectly.
-
Messages are sent using Samsung Galaxy S5 or Samsung Galaxy Note 3 with Android v. 5.0
Email clients on some mobile devices remove all CID elements in the message source. If a message thread includes multiple images, they will be available as attachments - but the last attached image will be inserted into every single empty CID element within the message thread.
Note: This is a known issue with Samsung Galaxy S5 or Samsung Galaxy Note 3 running Android v. 5.0, however, the issue may be present with other devices.
Resolution
To resolve the issues for the above scenarios:
Original image name clashes with an Outlook generated name
If you use Signature Manager Outlook Edition or Signature Manager Exchange Edition, avoid overly simple names (such as, image001); instead, use something that is likely to be unique.
Messages are sent using Samsung Galaxy S5 or Samsung Galaxy Note 3 running Android v. 5.0
This issue occurs independently of Exclaimer software.
If you wish to test this, simply disable the Exclaimer signature policies on your server then send a number of test emails (containing embedded images) back and forth between Outlook and one of the problem devices. In doing so, you will see the issue with images.
