Hello,

	You could do the following:

Setup to two contacts for each person:
personA-local
personA-remote

personA-local goes to their main e-mail address (ours is our exchange 
mail box). Time frame 24hrs

personA-remote goes to their mobilie device (ours goes to our phone).
Time frame 7-23

That way in the evening between 23-7 I do not get messages to my phone 
and when I am awake and check my main e-mail account I see all the 
notifications that came through.
