I have a coexistence environment (2013 SP1 CU6, 2007) in two sites. I create a test user on each site. When run any of Test-*Connectivity commands like (Test-OWAConnectivity, Test-ECPConnectivity) I got the following errors:

Hello

set internal urls for all services if not have: http://jaworskiblog.com/2013/04/13/setting-internal-and-external-urls-in-exchange-2013/
if have multiple domain try : Test-OWAConnectivity -identity:user@domain.com -MailboxCredential (Get-Crede

I have a single domain and the internal URLs already be set on all Client Access Servers but not be set on Mailbox Server.

Should I set the internal URLs on Mailbox servers?

Hello

The test couldn't test the internal URL of this virtual directory, because the InternalURL property isn't set
check internal url please

Hi,

Please run the following command to check the OWA configuration:

Get-OwaVirtualDirectory | FL Identity,*Authentication*,*url*

We can use Test-OwaConnectivity cmdlet in the following format (force to save the configuration to one specific DC in the same AD site):

Test-OwaConnectivity -ClientAccessServer: CAS01 -DomainController XXXX

Additionally, please directly access the OWA URL from IE to check whether it can be accessed. If there is any error message, please collect some event logs for further analysis.

Regards,
