New-RetentionCompliancePolicy

The Applications parameter specifies the target when Microsoft 365 Groups are included in the policy (the ModernGroups parameter is set). Valid values are:

• Group:Exchange for the mailbox that's connected to the Microsoft 365 Group.
• Group:SharePoint for the SharePoint site that's connected to the Microsoft 365 Group.
• "Group:Exchange,SharePoint" for both the mailbox and the SharePoint site that are connected to the Microsoft 365 Group.
• blank ($null): This is the default value, and is functionally equivalent to the value "Group:Exchange,SharePoint".

The Comment parameter specifies an optional comment. If you specify a value that contains spaces, enclose the value in quotation marks ("), for example: "This is an admin note".

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 Enabled parameter specifies whether the policy is enabled or disabled. Valid values are:

• $true: The policy is enabled. This is the default value.
• $false: The policy is disabled.

The ExchangeLocation parameter specifies the mailboxes to include. Valid values are:

• A mailbox
• A distribution group or mail-enabled security group (all mailboxes that are currently members of the group).
• The value All for all mailboxes. You can only use this value by itself.

To specify a mailbox or distribution group, you can use any value that uniquely identifies it. For example:

• Name
• Distinguished name (DN)
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

If no mailboxes are specified, then no mailboxes are placed on hold.

This parameter specifies the mailboxes to remove from the list of excluded mailboxes when you use the value All for the ExchangeLocation parameter. Valid values are:

• A mailbox
• A distribution group or mail-enabled security group

To specify a mailbox or distribution group, you can use any value that uniquely identifies it. For example:

• Name
• Distinguished name (DN)
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

The Force switch specifies whether to suppress warning or confirmation messages. You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate. You don't need to specify a value with this switch.

The ModernGroupLocation parameter specifies the Microsoft 365 Groups to include in the policy. Valid values are:

• A Microsoft 365 Group
• The value All for all Microsoft 365 Groups. You can only use this value by itself.

To identify the Microsoft 365 Group, you can use any value that uniquely identifies it. For example:

• Name
• Distinguished name (DN)
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

The ModernGroupLocationException parameter specifies the Microsoft 365 Groups to exclude when you're using the value All for the ModernGroupLocation parameter.

You can use any value that uniquely identifies the Microsoft 365 Group. For example:

• Name
• Distinguished name (DN)
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

The Name parameter specifies the unique name of the retention policy. If the value contains spaces, enclose the value in quotation marks.

The OneDriveLocation parameter specifies the OneDrive for Business sites to include. You identify the site by its URL value, or you can use the value All to include all sites.

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

This parameter specifies the OneDrive for Business sites to exclude when you use the value All for the OneDriveLocation parameter. You identify the site by its URL value.

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

The PublicFolderLocation parameter specifies that you want to include all public folders in the retention policy. You use the value All for this parameter.

The RestrictiveRetention parameter specifies whether Preservation Lock is enabled for the policy. Valid values are:

• $true: Preservation Lock is enabled for the policy. No one -- including an administrator -- can turn off the policy or make it less restrictive.
• $false: Preservation Lock isn't enabled for the policy. This is the default value.

After a policy has been locked, no one can turn off or disable it, or remove content from the policy. And it's not possible to modify or delete content that's subject to the policy during the retention period. The only ways that you can modify the retention policy are by adding content to it, or extending its duration. A locked policy can be increased or extended, but it can't be reduced, disabled, or turned off.

Therefore, before you lock a retention policy, it's critical that you understand your organization's compliance requirements, and that you don't lock a policy until you are certain that it's what you need.

The SharePointLocation parameter specifies the SharePoint Online sites to include. You identify the site by its URL value, or you can use the value All to include all sites.

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

SharePoint Online sites can't be added to the policy until they have been indexed. If no sites are specified, then no sites are placed on hold.

This parameter specifies the SharePoint Online sites to exclude when you use the value All for the SharePointLocation parameter. You identify the site by its URL value.

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

You can use any value that uniquely identifies the user. For example:

• Name
• Distinguished name (DN)
• Email address
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

This parameter is reserved for internal Microsoft use.
