Mailbox auditing log search only shows last 7 days

Question

I have mailbox auditing turned on for a mailbox, and the audit log age limit is set to 90 days.  When I run the non admin user access report however it only shows me auditing items for the past 7 days.  If i go to powershell, and run search-mailboxauditlog
it shows the same 7 days. Any suggestions?

Mailbox audit logs are generated for each mailbox that has mailbox audit logging enabled. Log entries are stored in the Audits subfolder of the audited mailbox Recoverable Items folder. This ensures that all audit logs are available from a single location,
regardless of which client access method was used to access the mailbox or which server or workstation an administrator used to access the mailbox audit log. If you move a mailbox to another Mailbox server, the mailbox audit logs for that mailbox are also
moved because they're located in the mailbox.
By default, mailbox audit log entries are retained in the mailbox for 90 days and then deleted. You can modify this retention period by using the
AuditLogAgeLimit parameter with the
Set-Mailbox cmdlet. If a mailbox is on In-Place Hold or litigation hold, audit log entries are only retained until the audit log retention period for the mailbox is reached. To retain audit log entries longer, you have to increase the retention period by
changing the value for the AuditLogAgeLimit parameter, or export audit log entries before the retention period is reached.
