Microsoft Defender: Updates to Export Quarantine Message cmdlet [MC1069558]

Coming soon to Microsoft Defender: Updated password functionality for downloading Quarantine items through the Export-QuarantineMessage cmdlet in Microsoft PowerShell.

[When this will happen:]

General Availability (Worldwide, GCC, GCC High): We began rolling out late April 2025 and expect to complete by late May 2025.

[How this will affect your organization:]

With this rollout, we will offer the -PasswordV2 parameter as a new experience that allows admins and users to pass plain text for their passwords when exporting Quarantine items in PowerShell cmdlet. Admins and users should use the -PasswordV2 parameter, because using the previous -Password parameter may cause errors and –Password won’t be available in the longer term.
