Microsoft Outlook Express problems

I created (with all your help) a fairly complex excel spreadsheet complete with many macros for a client. Part of the program will automatically email his daily updated sheets to me with just a click of the mouse but I seem to be having a problem with it getting to me correctly.

He uses outlook express and I use outlook. Would that be a problem? Because his �Sent� box does not show that the sheet has been sent. I helped him though the settings of express to see if he had his �copy message to sent box� checkmark was checked and it was. It shows that he sends all his email that he sends regularly just not the one that is automatically via the macro.

Thanks in advance for your help in this matter.

Sorry for the bump. Really need to resolve this issue. Does anyone have any ideas? Please.

Anyone.... please.... i beg of ya.... I have tryed several different things. None seem to get it to work correctly.
