Custom Audit Log Retention?

Posted on by Community Member

Hi all,

Our organisation would like to retain the D365 Sales audit logs for more than the OOTB 30 days.

The doco suggests that is should be possible to set up a custom retention policy (https://docs.microsoft.com/en-us/power-platform/admin/audit-data-user-activity) but we can't find any such setting. The documentation suggests we could retain the logs for up to 100,000 days (we only want 90 though!).

Note that I'm talking about the logs you get via the "Audit Summary View", not the "Read Auditing" logs which seem to go to the Office 365 Security & Compliance Center.

3rd party product is acceptable, prefer an OOTB solution however.

Thanks everyone.

RE: Custom Audit Log Retention?

Hi BigPhil,

The audit in "Audit Summary View" will not be cleared automatically.

Audit logs are stored in blocks. Each block contains approximately 3 months of logs. You can only delete the oldest block and you cannot delete the block currently in use.

Reference: https://www.qgate.co.uk/knowledge/managing-audit-logs-in-microsoft-dynamics-crm/

For example, in my environment, I have audit logs from August 8th, so I have two audit log blocks.

If I delete the first audit log block, then my audit log will start on October 1.

In summary, you do not need to customize audit retention, unless you manually delete the log, the old log will not be automatically cleaned up.

RE: Custom Audit Log Retention?

Hi,

We have a productivity app for Dynamics 365 CRM and PowerApps named Click2Undo which enables users to view Audit history of a record as well as undo changes and restore records to its previous known state with just a single click. By default Click2Undo grids show audit history for last 30 days, but you can also manually set number of days for which you want to show history. In your case it is last 90 days.

For more information, you can visit our website here.

Let me know if you have any other queries.

Thanks!

RE: Custom Audit Log Retention?

This is good news on one hand, but also bad in that it is hard to justify without seemingly ANY supporting documentation. Most organisations have policies governing this kind of thing so I'm surprised it seems to be so poorly implemented and documented. I appreciate the answer, looks like we may have to just hope that Microsoft doesn't change this implementation!

RE: Custom Audit Log Retention?

Hi BigPhil,

Yes, the documentation on Audit is indeed factually incorrect. It looks like the current Audit Log retention mechanism follows the D365 OP, not the Power Platform.

For Customer Engagement (on-premises), you may notice that auditing can significantly increase the size of the organization database over time. You can delete audit logs by going to Settings > Auditing > Audit Log Management. Additionally, you may want to stop auditing for maintenance purposes. Stopping auditing stops tracking for the organization during the period until auditing is started again. When you start auditing again, the same auditing selection is maintained that was previously used.

However, based on past patterns in the documentation, certain features in the documentation that are not released in the current version are often features that will be implemented in future versions. You can think of the documentation as a feature plan, in other words, the Microsoft team is developing this feature, but its description is already published in the documentation.

Of course, this is just my personal idea and does not represent any official opinion at all. Anyway, for now, you don't need to customize the review log retention.
