My organisation has a requirement that audit / security logs need to be kept for at least one year. In office 365 the logs available in the Audit Log Search are only kept for 90 days.
I am trying to find the simplest possible solution where we can download the logs to be stored locally. Ideally a product we can buy before we have to custom develop something.
I have looked at using the Search-UnifiedAuditLog powershell command but this does count as custom dev and I would also need to split the JSON return into individual columns.
The ideal end result would be a simple CSV file containing the days worth of results.
Has anyone seen anything like this available?
