Release-QuarantineMessage

The ActionType parameter specifies the release action type. Valid values are:

• Approve
• Deny
• Release
• Request

The AllowSender switch specifies that all future messages from the sender won't be quarantined. You don't need to specify a value with this switch.

If the message was quarantined because of a transport rule or blocked sender, messages from the sender can still be blocked in the future.

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

The EntityType parameter filters the results by EntityType. Valid values are:

• Email
• SharePointOnline
• Teams (currently in Preview)
• DataLossPrevention

The Force switch hides warning or confirmation messages. You don't need to specify a value with this switch.

Use this switch whenever you attempt to re-release previously released messages from quarantine.

The Identities parameter identifies quarantined messages for bulk operations. You identify the messages by using the syntax: value1,value2,...valueN. The value is a unique quarantined message identifier in the format GUID1\GUID2 (for example c14401cf-aa9a-465b-cfd5-08d0f0ca37c5\4c2ca98e-94ea-db3a-7eb8-3b63657d4db7).

You can find the identity value for a quarantined message by using the Get-QuarantineMessage cmdlet.

When you use this parameter, the Identity parameter is required, but the value is ignored. For example, use the value 000 for the Identity parameter.

The Identity parameter specifies the quarantined message that you want to release. The value is a unique quarantined message identifier in the format GUID1\GUID2 (for example c14401cf-aa9a-465b-cfd5-08d0f0ca37c5\4c2ca98e-94ea-db3a-7eb8-3b63657d4db7).

You can find the Identity value for a quarantined message by using the Get-QuarantineMessage cmdlet.

The ReleaseToAll switch releases the quarantined message to all original recipients. You don't need to specify a value with this switch.

This switch is required for the quarantine type SPOMalware.

If you previously used the User parameter or the ReleaseToAll switch to release the quarantined message to some or all of the original recipients, those recipients are skipped when you use the ReleaseToAll switch again.

You can't use the ReleaseToAll switch and the User parameter in the same command.

The ReportFalsePositive switch specifies whether to report the message as a false positive to Microsoft (good message marked as bad). You don't need to specify a value with this switch.

This switch is available only for quarantined spam messages.

The User parameter specifies the email address of the user to whom you want to release the quarantined message. You can specify multiple email addresses separated by commas.

You can use this parameter to release the message to recipients of the original message, or to any other email addresses in the organization.

If you previously used the ReleaseToAll switch to release the quarantined message to all original recipients, and you later release the message again with the User parameter, any original recipients you specify with the User parameter are skipped.

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.

The WhatIf switch doesn't work in Security & Compliance PowerShell.
