Cannot send mail from within word document

[tasuooooo]

Hello,

I'm using MS Office 2007.
When I'm trying to send a mail from a word document by clicking the office button on the top left and then "Send" -> "Email"
I get the following error: "Word could't send mail because of MAPI failure: "Attachment open failure""
I have no problem opening the file.
I get this message on all Word file I'm trying to send.



I was looking for a solution on the net but didn't find anything regarding to my issue, but all was talking about Office 2003 and hotfix not suitable to my office 2007.

Thanks a lot for your help...
Eli
