Add a new style to the default excel styles

[jcmckeon]

Hello All

This should be easy but I can't get it to work. I made and style in a workbook called Full Date Time. I want to have this be available in all Excel sheets I open from now on.

I saved this workbook as a template file, called it Book.xltx and put it in the XLSTART file but it doesn't show up in new Excel files.

Can someone give me guidance please?
