Direct effects for Operations**
Change in Sender Email Address
The change in sender email address may lead to confusion among users who are accustomed to the old address, potentially causing missed incident reports or miscommunication regarding data loss incidents.

Integration with Downstream Systems
If organizations have automated systems or workflows that rely on the old sender email address, these may fail to function correctly, leading to disruptions in incident reporting and response processes.
- roles: IT Administrators, Security Analysts
- references: https://learn.microsoft.com/purview/dlp-microsoft-teams

Opportunities**
Email Notification Management Improvement
The change in sender email address for Teams DLP GIR emails presents an opportunity to enhance the management of email notifications. By updating downstream systems to recognize the new sender address, organizations can improve the reliability of incident reporting and ensure that alerts are not missed due to filtering or misclassification of emails.
- next-steps: Conduct an audit of existing systems that rely on the current sender address and create a migration plan to update these systems to recognize the new sender address. Schedule training for IT staff on managing these updates.
- roles: IT Administrators, Compliance Officers, Security Analysts
- references: https://learn.microsoft.com/purview/dlp-microsoft-teams
Enhanced User Awareness and Training
With the change in sender email address, there is an opportunity to enhance user awareness and training around Data Loss Prevention (DLP) protocols. Educating users on the significance of these emails and how to respond can lead to better compliance and security practices within the organization.
- next-steps: Develop a training module that covers the importance of DLP emails, the changes to the sender address, and best practices for responding to incidents. Schedule training sessions for all relevant staff.
- roles: Compliance Officers, HR Trainers, IT Support
- references: https://learn.microsoft.com/purview/dlp-microsoft-teams
Streamlined Incident Response Process
The transition to a new sender email address can be leveraged to review and streamline the incident response process associated with DLP alerts. By ensuring that the new emails are properly integrated into incident response workflows, organizations can reduce response times and improve overall incident management.
- next-steps: Review current incident response workflows and identify areas for improvement. Update processes to include the new sender address and ensure that all team members are aware of the changes.
