Logo in OWA issues

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?

I would that this is more a problem of how the recipient is reading the emails.
If mail client is outlook and has blocked images then it would be blocked. Then can be if user is reading emails in plain text, also image will not be displayed.
Also can an issue with retrieving the image from your server, e.g. Recipient not connected or blocked to reach your domain, or your server can be too much loaded and so on.
webmail struggles with html signatures, mainly because you're using an html webpage to edit the html signature in the first place.....

There's not a way around it without resorting to a centralised signature or disclaimer facility added by the server to all messages.
Exchange 2007 can do this if necessary.

lciprianionut - I'm pretty sure this isn't the case - there's plenty of articles on the web to suggest that it should work, and I sent the instructions to the admin of another Exchange 2007 server and they tried it - worked fine on their setup.

totallytonto - again, plenty of discussion and instructions on the web on how to do this, so saying it's 'not possible' isn't correct. And Exchange 2007 can only send a standard, plain text message - it can't interrogate AD for user name, phone no etc which is what's required in the signature.

So any ideas as to why my Exchange 2007 OWA sends the logo OK internally, but not externally?
I never said its 'not possible', I just said it's a struggle. officially I don't think embedded images in OWA signatures are supported by Microsoft so that kinda supports my view that its a bit of a pain.

And Exchange 2007 can only send a standard, plain text message - it can't interrogate AD for user name, phone no etc which is what's required in the signature.

I know, but you didn't specify that was a requirement......



I recommend checking you can access the image in a web browser using the link you're adding to the signature from an external connection as it seems interesting it works internally and not externally.

Also, try forwarding a working internal message to an external recipient to see if it continues to work outside the office.

apparently OWA changes the image source reference to reference it from the internal mail server itself.
this means that internal staff will be able to see the image, due to their ability to authenticate against the source path.
external parties cannot :)

looking into this myself at the moment, so hope this helps...
