Probably before 2792, when the Dominatus Wars start and the galaxy wouldn't exactly be a nice place to colonise. In would say the period in betwen 2762 (Return of THEM) and 2789 (the Great Deceiver) is your best bet - the Galaxy was peaceful and relatively stable then, with the eyes of it's mayor inhabitants focussed abroad.
