Protecting and preserving users OneDrive data

What is data retention in OneDrive & why should it be turned on?

When an employee leaves your company, often they have files on their computer or in their OneDrive which would be useful for others taking on the role. Files they may have been collaborating on with others in your company. Or external guests that someone taking over their role would need access to. Protecting and preserving users OneDrive data matters for business continuity.
Take Adele as an example. She works in your organisation, but has decided to leave to pursue a career overseas. When she leaves, she dutifully turns in her computer. Sam, who is taking over her role, is given access to her emails to help him going forward.
But what about her files? Well, the files on her computer are exported and provided to Aaron. Except  Adele stored most of her files in her OneDrive account so what was sent to Sam from her computer was not useful.
Fortunately, your IT manager had OneDrive data retention turned on for your company. So when Adele’s 365 account was deleted, help desk was able to give Aaron access to her OneDrive files.
OneDrive data retention is about managing data after someone leaves the business. Making sure any documents the leaving user had can be accessed by someone else in the business. By default OneDrive data is deleted 30 days after their account is disabled, making it even more important you protect it.
Turning it on ensures that the user’s manager has access to the OneDrive files. It also enables an admin to set a backup in the case where a user does not have a manager in 365.

Back to Adele, who is leaving the business. Adele’s colleague Aaron will be taking over her role and will need access to Adele’s OneDrive files.

2. The deletion is synchronized to SharePoint

3. The OneDrive clean up job runs, and the Adele’s OneDrive account is marked for deletion.

4. Aaron, and Adele’s manager Mary are notified that Adele’s account will be deleted. By default, Aaron and Mary would have 30 days to access the data before it is deleted, but that can be changed.

a. If Adele didn’t have a manager in AD, OneDrive retention can be configured to give a back-up person access to the files. The backup person would be the same for all users leaving.

5. 7 days before the retention period ends, an email reminder is sent to Aaron and Mary.
