The reason is that the server that the application is talking to rejects the attachtment (wihout given a proper error message).
Tracing back the differences between what my applicaion sends out and what there apps sends, is the Content ID lines
There apps:
<documentFile href='cid:http://082142CB-493B-7DD9-B700-949C0E0D272B'>
Content-ID: <http://082142CB-493B-7DD9-B700-949C0E0D272B>
My apps:
<documentFile href="cid:BF16F1CE-418A-4FD0-8FF8-58218E33615A"/>
Content-ID: <BF16F1CE-418A-4FD0-8FF8-58218E33615A>
The only difference is the "http://" bit which is missing and needs to be added.
Can this be done??
Thanks
