KB20170323-1 Troubleshooting Cayosoft Administrator Exchange On-premises Connections

Published: March 23, 2017

Updated: June 5, 2018

Applies to: Cayosoft Administrator 3.x and above

Licenses needed: Enterprise or Exchange On-premises

Summary: There are three items that need to be correctly configured to establish a successful connection from Cayosoft Administrator to a Microsoft Exchange On-premises Server. These three items are: 1) the Exchange Server, 2) the security settings on the two servers, and 3) the connection settings within  Cayosoft Administrator.

Troubleshooting Exchange On-Premises Settings

Verify the TrustedHosts setting on the Exchange Server:

1. Open a Powershell prompt and run the command:

WinRM get winrm/config/client

2. See the example results below:

PS C:\> WinRM get winrm/config/client
Client
    NetworkDelayms = 5000
    URLPrefix = wsman
    AllowUnencrypted = false
    Auth
        Basic = true
        Digest = true
        Kerberos = true
        Negotiate = true
        Certificate = true
        CredSSP = false
    DefaultPorts
        HTTP = 5985
        HTTPS = 5986
    TrustedHosts

3.  If the results are empty like the are in the example above continue to step 4. Otherwise move to the next section of this guide.

4. Run the following command on the Exchange Server.

Set-item wsman:localhost\client\trustedhosts -value *

5. Check that the settings are applied, running the command again

WinRM get winrm/config/client

6. See the example results below:

PS C:\> WinRM get winrm/config/client
Client
    NetworkDelayms = 5000
    URLPrefix = wsman
    AllowUnencrypted = false
    Auth
        Basic = true
        Digest = true
        Kerberos = true
        Negotiate = true
        Certificate = true
        CredSSP = false
    DefaultPorts
        HTTP = 5985
        HTTPS = 5986
    TrustedHosts = *

 Note the last line of output have changed to "TrustedHosts = *".

Verify the Cayosoft Administrator Configuration

Restart the Cayosoft Administration Server - Reboot the Cayosoft Administrator Server. This is to make 100% certain that we didn't have some cached credentials somewhere.

Verify service account permissions - Verify the service account holds the Exchange Role Organizational Management
