Before taking a journey through the lifecycle of an item in Sharepoint, I recommend reading the following Microsoft Docs covering retention in M365. These docs will give you the requisite knowledge of the retention features in M365 before we dive a bit deeper here.


 



 


Retention policies help you retain what you need to preserve and delete what you no longer need. What is the difference between a retention label and a retention policy? Let’s take a step back to explain a few gotchas first:


 



  1. Labels are applied at the item level (folder, document, or email) whereas retention policies are applied at a container level (mailbox or site).

  2. All retention policies contain at least one retention rule. The rule defines how long an item is retained and/or when it is deleted. You will notice that when you create a retention policy, the associated retention rule is automatically created.

  3. A retention policy defines where the rule(s) are applied.


 


A retention label is simply a retention rule with a few extra features:



  • You have can trigger a disposition at the end of the retention period

  • You can declare the item as a record or regulatory record

  • The enforcement point can be based on an event or when the label was applied

Now that you understand the difference between a retention label and a retention policy, our team is ready to take you through a visual representation of the different containers in which an item may reside throughout its lifecycle in SharePoint. The scenarios will show what actions are taken on the item based on each potential retention scenario. 


 


We already know that retention takes precedence over deletion and that the longest retention period always wins. What happens if I have a 2-year delete policy applied to a site alongside an item that has a 3-year retention label? What happens if I apply a 3-year delete label to an item that resides in a site with a 10-year retention policy? While the principles of retention will always be your north star, it can help to have some visual guidance to understand where these items move and when.


 


For the scenarios below, the Retention Policy (Site level) and the Retention Label (item level) are both configured based on the items creation to Retain and then Delete:


 



  • The Retention Label (item level) is configured to retain for 3 years and then delete

  • The Retention Policy (site level) is configured to retain for 10 years and then delete

  • The Deletion policy (site level) is configured to delete after 2 years


*NOTE: The Recycle Bin is not indexed and therefore unavailable for searching. As a result, an eDiscovery search cannot find any Recycle Bin content on which to place a hold.
