Arabic Support In Office 2004 For Mac Os


I recently purchased an Macintosh laptop with 10.4.2 OS version.

I want to know whether Office 2004 supports arabic language.
If i want to open my all the spreadsheets or documents created in office 2003 in office 2004 for Mac, then is it possible or not.

If no, then what is the soultion.

I downloaded something called Openoffice,but it does not have anything like Outlook mail client
