"ADOperationException" error when OWA text verification fails in Exchange Server 2016

Applies to: Exchange Server 2016 Enterprise EditionExchange Server 2016 Standard Edition

Symptoms


In a Microsoft Exchange Server 2016 environment, consider the following scenario:

  • You have multiple Active Directory (AD) domains.
  • The Exchange Server(s) and the user accounts are located in different domains.

  • You run the Compare-TextMessagingVerificationCode cmdlet to verify the text messaging verification code that the user specified.

In this situation, text messaging doesn't work in Outlook Web App (OWA) and you receive the following error message:

Microsoft.Exchange.Data.Directory.ADOperationException: The requested search root 'ServerName.contoso.com/Synched Users/Users' is not within the scope of this operation. Cannot perform searches outside the scope 'contoso.com'.

Cause


This issue occurs because the ViewEntireForest parameter is set to false during the Compare-TextMessagingVerificationCode cmdlet initialization.

Resolution


For Exchange Server 2016, install Cumulative Update 9 or a later cumulative update for Exchange Server 2016.

Status
