Good day
We are having a problem with Excel. When we send Excel files to people via email they can’t open them. The computer states that the file is a “.dat” file and cannot be opened.
What can this be? When the people send the files to me on my Mac then I can open it, but when it is sent to other people also working on Macs and some on PC then they can’t open the files. On the Macs we have Office 2008 and on the PC’s we have Office 2007.
Please help me. :-{
