What to set as mx records

Hi all,

i am very new at office365 and have already a question.

I want to send amd receive EMails with my primary EMail Address, lets say anywhere@anything.de.

I am Owner of this Domain and can deal with the DNS entries. 

Good, sending as anywhere@anything.de is no Problem. 

But what to set as mx records on my Domain?

Now i found several Documentation what is to set. I should set the mx to "MS=msXXXXXXXX". For mor informations i should look at this link: https://portal.office.com/adminportal/home.

This Link i can not open, my account is there not known.

Can anyone help to find the right settings?
