I'm having problems opening excel files with Office 2007created in Mac Office 2008, I get the following message: "The file you are trying to open "XXXXXXXX" is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"
The excel files have the unknown file icon also, the excel documents are stored on a NETGEAR ReadyNas NV+ with full rename & delete permissions.
I think this is related to Mac Office 2008 excel files only cause the message does not appear when opening excel document made in Mac Office 2004 but I will confirm this tomorrow afternoon.

Thanks

In my experience this error ususally occurs when you open an Office 2007 file where the filename extension is set as '.xls'. Normally Office 2007 expects files saved in the latest format to be denoted as '.xlsx'. However, the file should still open okay if you accept that warning message.

I have personally had no problems exchanging files between Office 2007 (Windows) and Office 2008 (Mac).

What's the file extension on the files where you're seeing this message?

When you're saving the files in Office 2007, what format are you saving them as? (e.g. Office 2007 .XLSX, Office 2000/2003 compatible .XLS, or .CSV etc)
