How to add a HTML email signature (including embedded image) to Outlook Web Access
Outlook web access does not allow the inclusion of images by default. However it is possible to embed the image within the signature.
First upload the image you wish to include to a web server and make a note of the full path. ie, http://www.yourdomain.com/images/companylogo.jpg.
Then create a new signature in Outlook and ensure the path of the image on the signature points to your webserver. You can find the raw signature files in “C:\documents and settings\username.domain\application data\microsoft\signatures” on Office 2007/XP.
You can then edit the raw signature in Notepad.This is an ideal opportunity to tidy up the messy html created by Outlook when designing the signature in the first place. Find the image src and edit to point to the full path of the hosted image

Send an email with the signature embedded to the users email address and open the email within OWA (in IE). Copy the signature then go into Options -> Email Signatures and paste in the signature.
Thank you so much =) This was VERY helpful ^_^

All I’m getting is a red X with the URL where the image should be. Is there a setting I can’t find or am I SOL? I feel like I’m so close…

Hi Mike,
If you right click/properties the red box, does it show the path of http://www.yourdomain.com/images/logo.jpg
Can you browse to this path using ie or firefox? It sounds like the logo is not available on your webserver from the public internet.
If you email me the html from your signature I’ll happily check it
Thanks for the comment and thanks for reading.

When I do this, the image does not show up in places like Live mail or Gmail. If I look at the properties of the image, it shows a weird attachment email (I paste it) instead of the simple URL that I entered into the signature source .htm and .xml files. Here is the url that shows: [https://mail.solutioncenter.biz/owa/attachment.ashx?id=RgAAAACC0uvJm3kqQJgQsFkFx4OfBwC2HU8uP94HQ5DjAPgDz%2bTJAAAAcmdoAAB9oxa4uJuTTI%2fbaY4YEEAPAD6Hr5vrAAAJ&attcnt=1&attid0=EAB05YFbTPIyRIJa222%2fabkz]

I have been trying to get this to work on my network for some OWA users but emailing gmail or yahoo just attaches the logo instead of embedding it like Outlook does. Any ideas there? The logo is accessible but just as an attachment and not in the email body.

@Russell – If the users use a mail client in gmail it works…but for the embedded signature it just looks like that’s the way the browser based client handles any embedded content….it is odd though….

Hi I created my html sig successfully and I was hoping that each time i update the image on our web server, the image in each of my new emails would update…It doesnt, it seems that after you set your sig, outlook somehow embeds the image rather than pulling it from the server.
Is there any way round this so that i can have my sig update automatically when i update my image online?

See if the path to the image contains the filename and if your new replacement has the identical filename. If not, fix the path accordingly.

go to options, under privacy and junk email, uncheck ‘Block external content in HTML email messages’
