We've added a logo to our outgoing e-mail signature, and this is not a problem on PCs using standard Outlook.
For users using OWA, I have been able to incorporate the logo by hosting the image externally (ie not on the internal network), and using HTML to reference it in the signature.
This works fine when the user sends an e-mail to someone on the same domain, but when an e-mail is sent outside of the domain, the recipient just gets the url shown in the e-mail (eg [http://domain/img/image.png
] ) - doesn't even get the usual 'red x in a box' that normally indicates an image that's not valid.
We are using Exchange 2007 on Server 2008 - is there a setting somewhere that I'm missing that allows the image to be sent to external recipients?
