Please confirm me my daily sending limit, and also tell me if the limit is same for sending emails through browser/outlook.com and microsoft outlook (part of MS Office). Moreover, is the limit aggregated if I send through both sources i.e. 300 from outlook.com plus 300 from microsoft outlook, total 600 per day. Moreover, if I subscribe to Hotmail plus, what will be my daily sending limit?

Also, if I've already sent 300 emails a day and have to reply to a response that I received against previously sent emails (or reply to a response received against an email sent that same day), will I be restricted from doing so?
