Easy. If I receive an email from them that contains an outlook 365 email header, then they use Outlook 365. So then just send them the command that works with outlook 365. It's literally that simple. I have a good idea of what the amount of work because I've sent the same request about 100 times and have learned quite a lot, both through conversations, email, litigation and other's litigation. If experience isn't helpful then I ask for a small slice and use that to calibrate their estimate. Estimates are usually very wrong, like it was with Seattle.
