How do I include images for an OWA signature?
Any images used in templates for OWA signatures must be linked using a URL and must not be embedded. To do this, choose the insert image option from the template editor toolbar to open the image window:
In the location field, type the required address for the image. Alternatively, if the required address is stored in an Active Directory field, you can use the arrow associated with the location to select the appropriate field.
Required images must be available on a computer that can be viewed externally - for example, on a web server.
