Can't send HTML thru Exchange 5.5

Am I missing a setting somewhere?

We have MS Exchange 5.5 on our mail/proxy server, receiving HTML messages is no problem but when we try to send a message in HTML format it comes out as plain text, no colors or font changes anywhere. Internally the messages come out fine, but sent accross the Internet people receive them as plain text.

I don't even know where to begin looking for something like this. I'm hoping someone here can help!

TIA

Kevin

Just had a thought, since we receive the messages correctly internally could this be a problem in the router?

 

Check the IMS connector properties.

 

Thanks for the response, you're right there was no check mark in the HTML box there and a couple of other places as well.

All is working as it should.

Thanks again!
