• With people outside my organization
• Only with people inside my organization - Select Next, and on the Protection Actions page, displayed in Figure 4-52, configure the following options:

• When content matches the policy conditions, show policy tips to users and send them an email notification. You can also customize the tip and email message.
• Detect when a specific amount of sensitive info is being shared at one time. Defaults to 10 instances.
• Send incident reports in email.
• Send alerts if any of the DLP rules match.
• Restrict access or encrypt the content in Microsoft 365 locations.
- By default, users are blocked from sending email and Teams chats and channel messages that contain the type of content you’re protecting. On the Customize access and override settings page, you can choose who has access to shared SharePoint and OneDrive files. You can also decide if you want to let people override the policy’s restrictions. Select Next.
- On the Test or turn on the policy page, there are three options:
• I’d like to test it out first (Show policy tips while in test mode)
• Yes, turn it on right away
• No, keep it off. I’ll turn it on later - Select the appropriate option and select Next.
- Review your settings for this policy and select Submit.
- It might take a moment until the policy is created. Then select Done.
Depending on the size of your organization, you should consider rolling your DLP policies out gradually to assess their impact and test their effectiveness. A DLP policy could unintentionally block access to documents that staff require for their daily work. It is therefore recommended that you pilot the deployment of DLP policies and initially limit the location and scope.
Once the initial test deployment is successful, you can roll the DLP policies out to a wider audience. Throughout the process, you should monitor the DLP reports, incident reports, and any notifications to make sure that the results are what you intend.
