Excel for a user of a MAC they’ll always get a winmail1dat.file
I am in HTML mode and currently using an Outlook 2003 in Win7 but every time I’m trying to send an excel for a user of a MAC they’ll always get an winmail1dat.file which is if you will email in a rich text format but I am not using that. In every plain text that I’ve send they’ll get an .xls and to my friend using Mac he gets the same .xls file too. What could you say about this? Is this fine? Or not?
And can you give me some suggestions on how could I send the xls.file in plain in just for one time user?
