 ### -RetryDistribution
 The RetryDistribution switch specifies whether to redistribute the policy to all Exchange Online and SharePoint Online locations. Locations whose initial distributions succeeded aren't included in the retry. Policy distribution errors are reported when you use this switch.

+The RestrictiveRetention parameter specifies whether Preservation Lock is enabled for a retention policy or retention label 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.
