Thanks for the quick reply. I tried disabling the 'Keep messages in all folders for this account on this computer' option but embedded images are still included in the email messages. Any other advice?

I tested by sending myself a new message with an embedded image after the change was made. All new images should include the header only correct?

Ok. Not exactly the solution I was hoping for but I guess there is no other option. I just want to thank you very much for all of your help with this. I'm quite impressed with the amount of time and effort you put into assisting me here. Happy New Year!
