Description
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Set-RetentionPolicy "MyPolicy" -RetentionPolicyTagLinks "MyRetentionPolicyTag"
This example modifies the policy MyPolicy to link the retention policy tag MyRetentionPolicyTag with it.
The Identity parameter is positional, which means you can use it without the -Identity label in the supported location in the command (in this case, first). For more information about positional parameters, see About Parameters.
Parameters
-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
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 Force switch hides warning or confirmation messages. You don't need to specify a value with this switch.
Use this switch to hide the confirmation prompt when you use the RetentionId parameter.

-IsDefault
Applicable: Exchange Online
This parameter is available only in the cloud-based service.
The IsDefault switch specifies that this retention policy is the default retention policy. You don't need to specify a value with this switch.
When you use this switch, you get a warning that this retention policy replaces the current default retention policy (the policy where the IsDefault property value is currently True) as the default. By default, the default retention policy is named Default MRM Policy.
Note: Changing which retention policy is the default might or might not affect new and existing mailboxes based on the value of the RetentionPolicy parameter on all mailbox plans:
- $null (blank): Changes to which retention policy is the default are continually reflected in new and existing mailboxes.
- A retention policy is specified: The value of the RetentionPolicy parameter for all mailbox plans should be $null (blank) or match the Exchange retention policy that's configured as the default policy for the organization. Otherwise, the experience might be inconsistent when creating new mailboxes, enabling disabled mailboxes, and changing licenses. For more information see Mailbox plans in Exchange Online.
If a mailbox is assigned an Exchange retention policy that's not the default policy, the RetentionPolicy value of the mailbox is overwritten when changing licenses. You need to manually reset the RetentionPolicy to the original value.
Changes to the default retention policy that affect existing mailboxes can potentially saturate the network if there are hundreds or thousands of mailboxes that require updates.

-IsDefaultArbitrationMailbox
Applicable: Exchange Online
This parameter is available only in the cloud-based service.
The IsDefaultArbitrationMailbox switch configures this policy as the default retention policy for arbitration mailboxes in your Exchange Online organization. You don't need to specify a value with this switch.
This parameter isn't available in on-premises deployments.
Parameter properties
| Type: | SwitchParameter |

-Name
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online
The Name parameter specifies a unique name for the retention policy.
Parameter properties
| Type: | String |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |

-RetentionId
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online
The RetentionId parameter specifies the identity of the retention policy to make sure mailboxes moved between two Exchange organizations continue to have the same retention policy applied to them. For example, in a cross-forest deployment or in a cross-premises deployment, when a mailbox is moved from an on-premises Exchange server to the cloud, or a cloud-based mailbox is moved to an on-premises Exchange server, this parameter is used to make sure the same retention policy is applied to the mailbox.
It's not normally required to specify or modify the RetentionId parameter for a retention tag. The parameter is populated automatically when importing retention tags using the Import-RetentionTags.ps1 script.
Parameter properties
| Type: | Guid |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)

-RetentionPolicyTagLinks
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online
The RetentionPolicyTagLinks parameter specifies the identity of retention policy tags to associate with the retention policy. Mailboxes that get a retention policy applied have retention tags linked with that retention policy.
Parameter properties
| Type: | RetentionPolicyTagIdParameter[] |
| Default value: | None |

Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
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.
