I have a client who received in email in Outlook from another Exchange User with 2 embedded images. The issue was that the source of the images are from the users exchange mailbox: (see below):
<p><font size=2 color=navy face=Arial><span style='font-size:10.0pt;fo
Arial;color:navy'><img border=0 width=96 height=75 id="_x0000_i1026"
As such the recipient is asked for a login if they attempt to access the image. Does anyone have any idea how this can occur?
