The mail app help!

Hi guys, thought id make a thread on this as i couldn't find it after searching on the forum and internet for an hour.

My question is, how do i get the mail app on my macbook to only show the top 50 recent messages from my hotmail account just like i do with my iPhone. Is this possible? Also I have two mailboxes, how to i view messages from both like i do on my iPhone, instead of individually selecting the mail box. Id like all of the mail to appear from both mailboxes when i open he mail app. I think i did something wrong as it used to do this before i clicked on 'display selected messages only' but i can't seem to reverse what i did.

Help would be greatly appreciated!
Thank you!

 

Thank you for the reply! still cant find how to only download the latest first 50 emails hmmm :L
