Beginning July 24th, 2017, we’re making some important changes to SharePoint Online Site Collection Admin Audit Logging.

Site Collection Admin Audit Logging enables administrators to keep a reliable log of what is happening with important content on a site collection. Administrators are able to retrieve the entire history of actions taken by a particular user and can also retrieve the entire history of actions taken during a particular date range.  For example, site administrators can use auditing to track how documents and items are used throughout a site collection.

Beginning July 24th, 2017 for First Release enabled Office 365 Tenants, we will be making changes to the SharePoint Online Site Collection Administration Audit Log feature by enforcing a 90-day retention period. Customers who used this feature previously will be automatically updated to the new retention policy and settings. New customers who subscribed to Office 365 after this change will be forced to use the 90-day retention period. Customers can either accept the default of 90 days or input a smaller number of days.

Important: This change does not impact the Unified Auditing experience from the Office 365 Security & Compliance Center.

Frequently Asked Questions

What does this mean for existing Office 365Tenants?

The SharePoint Online Site Collection Admin Audit Log feature is primarily used by a small percentage of our Office 365 customers for their own site auditing. Existing Office 365 customers who currently use the SharePoint Online fall in to one of four categories of audit log usage.

Audit Data? Trimming Set? Experience after change
Yes Yes Enforce 90 days to retain audit log data if the value is set to greater than 90 days. Leave the established document library path for storing audit data longer than 90 days.
Yes No Set retention to 90 days and set the document library path to the default document library.
No Yes Enforce 90 days to retain audit log data if the value is set to greater than 90 days. Leave the established document library path for storing audit data longer than 90 days.
No No Set retention to 90 days and set the document library path to the default document library.

 

How can I view data that’s beyond the 90-day retention period?

Once the 90-day retention period is met an Excel file will automatically get created in the document library specified. These files will contain audit data from specific periods of time. The data will not be lost. Instead the data will be found in an Excel file.
