This user sends the files in attachment as XLSX; but when the the receiver while saving it saves as ZIP. I tried the IE 8 Internet Option but it s not working. File sending in MS office 2010 and received using Office 2010. Please suggest Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
