Hi. I experienced the same when our company migrated to gmail, however, developed a solution that is straightforward.

All you need to do is add a parameter for each element. For example, to change the fill colour simply add a parameter and change the Default Value to the desired colour (eg #code or colour name). Set the parameter to Hidden prevents the user from seeing it when the report is run.

For borders, same concept except you need to add the colour (eg black), width (eg 1Pt) and style (eg Solid).

Hope this helps! [Richard Little]
