You have a Microsoft 365 E5 subscription that contains a Microsoft SharePoint Online site named Site1. Site1 contains a file named File1.
You have a retention policy named Retention1 that has the following settings:
• Retention items for a specific period
o Retention period: 5 years
o At the end of the retention period: Delete items automatically
Retention1 is applied to Site1.
You need to ensure that File1 is deleted automatically after seven years. The solution must NOT affect the retention of other files on Site1.
