Registered myself a Office 365 trial account some time ago:

As self education, i wanted to create a bulk administration script for Office 365. This to bether understand O365 and how PowerShell works with it.
I ended up writing a bulk administration script with the following features:
-Create Office 365 users from a list of users in a CSV file. Password from created users are exported to a txt file.
-Delete Office 365 users from a list of users in a CSV file.
-Choose what services to disable for all users or users from a list in a CSV file.
You can find the script over at TechNet:
