How to: Word mail merge with Excel in groups

Hi all,

I hope that someone can help me. 

We promote the creation of groups, so we can close the network drives.

A lot of users are creating mail merge documents in Word and use an excel as source.

But when the excel file is in a group it is not possible to access it.

Does anyone know if its possible at all? or will be in te near future?

Kind regards,

René
