Hello!

We're about to move mail from one 365 tenancy to another and we'd like to minimise downtime and NDRs. I was hoping to have mail delivered to pmg which would then hold it until we can release it, pointed at the new location. I'm sure I've done this before but I don't remember how - maybe I put in dummy destination details until it was time? Has anyone done this and if so, how'd it work?
