Office 365 Powershell

I have a local HR system. I want to update data in office 365 from the local system. I require a set of scripts to complete the following functions. So we can reset data incase of a problem. I need all scripts to have a 1st run option, where you will connect to office 365 and download the data into the database. In future all changes will then be one way from the local database to office 365. User Table ID Username - unique First name Last Name Display Name Job Title Department Office Office Phone Mobile Phone Fax Number Street Address City State or Province Zip or Postal Code Country or Region Last Login Mailbox Size Number of unread emails since last login Enabled ** if this is changed from Y to N you will disable the mailbox License type -------- Email Alias You will add remove alias email address, after 1st run. If there is an alias in o365 and its not in the database you will remove the alias from 365. If it exists in the database and not office 365 you will create it.
