Hi Graham, thanks for the reply.


I just like how lightweight sumatra is and its worth the trade off with some other features I like.


Thanks for the link I have everything checked so I think its Sumatra itself.


Is it possible to have a diff default outlook previewer but keep sumatra is main default overall?


Previewer aside is it possible for a VBA solution as often I want to open the attachment to work on rather than just preview?


Thanks
