Retention Labels Inheritance in SharePoint library, folder or document
In Microsoft Purview Data Lifecycle Management, you can create and publish retention labels (ex. Retain for 10 years and then dispose of them) for files within the SharePoint platform (ie. SharePoint, Teams OneDrive).
When dealing with Manual labeling of documents within the SharePoint platform, does each file need to be manual labeled?
The simple answer is NO. Let us look two options for applying retention labels:
- Manual retention labeling - You can manually apply retention labels for each file. This will require the employee to be trained on how to apply a published label.
Apply retention labels to files in SharePoint or OneDrive - Microsoft Support
- Label Inheritance – Here is where the NO comes into play. You can have users apply a retention label to a folder, and then have the users move files into that folder. All files in that folder will inherit the folder’s retention label.
Note - Remember check the licensing required for this Folder Inheritance functionality (see "Service Descriptions" link below) to be sure this will work in your tenant.

Data Loss Prevention (DLP) - Notifications with Exchange thick client and the M365 web client.
Can an organization allow its users to override a Microsoft Purview DLP block in Outlook for Exchange Online? The simple answer is YES.
Here is a screenshot of how you set that up in your DLP Rule (which is part of your DLP policy).
Thick Client Experience
Here is a screenshot of what the user will see in the Outlook thick client if they try to send an email containing data that is part of a DLP policy.
At the top of an email, the user will see a policy tip that explains the reason for the DLP block, and if you have the override enabled in the policy, the user will have a link to Override the DLP policy. Here is an example.
When you click on the Override link, here is where you can enter the reason for the Override.
Once the override is done, then you can send the email.
Web Client Experience
Here is a screenshot of what the user will see in the Outlook thick client if they try to send an email containing data that is part of a DLP policy.
At the top of an email, the user will see a policy tip that explains the reason for the DLP block, and if you have the override enabled in the policy, the user will have a link to Override the DLP policy. Here is an example.

Once the override is done, then you can send the email.
