Mailbox Audit Log searches fail with exception "ErrorInvalidServerVersion" in Exchange Server 2016, 2013, and 2010 coexistence environment

  • Article
  • Applies to:
    Exchange Server 2016, Exchange Server 2013, Exchange Server 2010

Symptoms

Consider the following scenario:

  • You have an Exchange coexistence environment that includes mailboxes that are hosted on Microsoft Exchange Server 2016, 2013, and 2010.
  • You move your arbitration mailboxes to Exchange Server 2016.
  • You enable Mailbox Auditing for mailboxes that are hosted on Exchange Server 2010.
  • From the Exchange Management Shell on Exchange Server 2016, you run either the Search-MailboxAuditLog or New-MailboxAuditLogSearch command to search the Mailbox Audit Logs for the mailbox that is hosted on Exchange Server 2010.

In this scenario, the audit log search fails.

If you run the Search-MailboxAuditLog command, an error message is returned in the Exchange Management Shell that resembles the following:

The Exchange Web Services returned an error while trying to access the audit log.  Reason: '','ErrorInvalidServerVersion','The specified server version is invalid.'
     + CategoryInfo : NotSpecified: (:) [Search-MailboxAuditLog], AuditLogServiceException
     + FullyQualifiedErrorID : (Server=E2K16,RequestID=<GUID>,Timestamp=DateTime) [FailureCategory=Cmdlet-AuditLogServiceException] AF0D01B1,Microsoft.Exchange.Management.SystemConfigurationTasks.SearchMailboxAuditLog
     + PSComputerName : E2K16.contoso.com

If you run the New-MailboxAuditLogSearch command, no error is returned in the Exchange Management Shell. However, Event ID 4002 is logged in the Event Viewer when the server tries to run the search:

Log Name:      Application

Source:        MSExchange AuditLogSearch
Date:          <DateTime>
Event ID:      4002
Task Category: General
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      E2K16.contoso.com
Description:
A runtime exception occurred in AuditLogSearchServicelet's worker while processing a request. Exception: 
Microsoft.Exchange.Data.ApplicationLogic.AuditLogServiceException: The Exchange Web Service returned an error while trying to access the audit log. Reason: '','ErrorInvalidServerVersion','The specified server version is invalid.'.
...

Cause

This behavior is by design. If the arbitration mailbox was moved to Exchange Server 2016, the Mailbox Audit Log searches are run through Exchange Web Services by having a RequestVersion value of "Exchange Server 2013." When this request is presented to Exchange Server 2010, the response is an "ErrorInvalidServerVersion" exception.

Resolution

To fix this issue, run the Search-MailboxAuditLog command on Exchange Server 2010 directly when you search mailboxes that are hosted on Exchange Server 2010.
