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'.
