It is ok with Google mailbox, there are native Office 365 instruments that will help you to migrate your Gmail to Office 365. But as for Google Calendar, you will have to transfer your data manually. See the instructions how you can do this below.
First you need to sign up to your Google Apps account and open GCalendar of a user that you want to migrate to Office365.
Choose My calendar -> Settings on the left-hand pane.
Then click on the “Export calendar” link and safe the .ICAL file to some specific location. Note that the file will be compressed. You need to unzip it before you can use it with Office.
Now open Outlook desktop program.
