Your best bet is the Export-DlpPolicyCollection cmdlet: https://learn.microsoft.com/en-us/powershell/module/exchange/export-dlppolicycollection?view=exchange-ps
You can also take a look at M365 DSC, which includes DLP policies configuration: https://github.com/microsoft/Microsoft365DSC

Hi Michev,

Thanks for your quick reply, we have tried Export-DlpPolicyCollection as well. but unfortunately not working. Tried the below code snippet as resultant below xml schema got exported to xml file at given location.

$file = Export-DlpPolicyCollection
Set-Content -Path "C:\My Documents\Contoso PII.xml" -Value $file.FileData -Encoding Byte

Result:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<dlpPolicies />

Though our policy containing multiple rules and actions, nothing was exporting.

Also when ever there is a change in any particular DLP policy we have to apply the same changes to the policies created based on this particular policy template using PowerShell, can you help over this scenario as well.

Hi @Koteswararao Kata ,
Please try to create a new DLP policy in Exchange admin center and try to run the above command again. Then check to see if the correct XML file is exported.

At present, I have not found a command line to update all DLP policies that apply the same custom template at the same time. I will continue to search and research, and I will update if there are any findings.

Export-DlpPolicyCollection only working to export the exchange level DLP Policy, But in our case we want to export Office 365 Security and Compliance center DLP Policy as template.

Hi @Koteswararao Kata ,
According to my test, you could following the steps in the below link to connect to Security & Compliance Center PowerShell, then run the following command to export the DLP policy in Office 365 Security and Compliance center.

$file = Export-DlpPolicyCollection Set-Content -Path <> -Value $file.FileData -Encoding Byte

Please refer to: Connect to Security & Compliance Center PowerShell
