Relevant Products: Signature Manager Exchange Edition | Signature Manager Outlook Edition
WARNING! From 1st April 2021 Exclaimer will no longer be renewing any Software Maintenance Agreement (SMA) for Mail Disclaimers.
Please be assured that the Exclaimer Support team will provide support until your SMA is active.
However, we recommend that you contact the Exclaimer Sales team to discuss your requirements for an upgrade to Signature Management Exchange Edition or Exclaimer Cloud - Signatures for Exchange.
If you are using an Exclaimer On-premises product, you can use embedded and/or web hosted images when creating signature content.
Please see the pros, cons and other considerations for both image types summarized below:
Embedded images
Embedded Images
Pros
- Displayed automatically in Outlook
- Easy to manage
Cons
- Adds to the file size of the message
- iOS devices strip out embedded images when replying to or forwarding messages, and they can be added as attachments
File Format
The recommended formats are:
- JPG
- JPEG
- PNG
- GIF
Size
For optimal mail client support and to stop signature images from appearing larger than expected - an image should be the actual size you want it to be displayed in signatures.
For example, if your company logo should be displayed at 200 x 100 pixels in the signature, ensure that the image file you choose is already at 200 x 100 pixels.
For compatibility with mobile devices, we recommend that banner images should be no more than 600 pixels in width.
Location
Ideally, images should be stored locally on the machine where the Exclaimer product is installed.
For example:
If necessary, network drives can be used. In this case, you must specify the full UNC path to the image;
for example:
Mapped network drives are not supported.
Permissions
If an image is stored locally, ensure that the Network Service account has read permission to its location.
If the image is stored on a network drive, ensure that Everyone has read access to its location.
Web hosted images
Pros
- No considerable increase to the message size
- Will not be stripped out by iOS devices
Cons
By default, Outlook blocks the automatic download of web hosted images, so recipients must click on Outlook’s security banner to display them.
File Format
The recommended formats are:
- JPG
- JPEG
- PNG

Location
You can upload images to your own website, or use one of the many image hosting services available online. Having done this, you need to specify the URL for the image within your Exclaimer product.
For example:
Permissions
Your chosen location for uploaded images must be publicly accessible.
