One of the biggest mistakes in Office 365 management is the assignment of the Global Admin permission to user accounts. Because, even though you manage Office 365 from your browser which automatically signs you in with your user account, you should always perform administration with your admin account. So, change it, and fast.

Data Loss Prevention is one of the powerful security and compliancy options within Office 365. In this post I'll configure two policies based on templates that are maintained by Microsoft. Please note that you need to take a few things in consideration when configuring data prevention:
- Privacy - All emails will be scanned and especially during testing and tuning phase it might be required you read (parts) of the emails that are being sent. You need to discuss these matters with you compliancy and privacy officers
- SOC mailbox - You need to place to which alerts need to be sent. This could be your compliancy mailbox or the mailbox of your SOC team but it needs to be accessible ONLY by authorized employees.
- Updates to the policy might take 24 hours to take into effect, but as far as I have seen 15 minutes is more common
- All configuration is done in the Security and Compliance portal found at: https://protection.office.com
