Failed to update the Exchange server in MAM Addressbook. Connecting to remote server failed with the following error message : WinRM cannot process the request. (4370181)

Failed to update the Exchange server in MAM Addressbook. Connecting to remote server failed with the following error message : WinRM cannot process the request.

The connection URI used for the powershell command to connect to Exchange is created from the Exchange server name + domain. If the domain is not detected correctly, you can adjust it in Archive Manager SQL Database. Problem is typical for CHILD/PARENT domain type environments.

46    22.322596    15452    exchangePAMManagerSv.exe    ThreadId: [10]; PowerShellConnection.Connection error:  >> 'Connecting to remote server ex2016.contoso.com failed with the following error message : WinRM cannot process the request. The following error occurred while using Kerberos authentication: The computer ex2016.contoso.com is unknown to Kerberos. Verify that the computer exists on the network, that the name provided is spelled correctly, and that the Kerberos configuration for accessing the computer is correct. The most common Kerberos configuration issue is that an SPN with the format HTTP/ex2016.contoso.com is not configured for the target. If Kerberos is not required, specify the Negotiate authentication mechanism and resubmit the operation. For more information, see the about_Remote_Troubleshooting Help topic
 

For example if the Exchange server name is EX2016 and the sub-domain is "intra.contoso.com". MAM will create the connection URI to ROOT level "ex2016.contoso.com". To change the URI to child domain level ex2016.intra.contoso.com, set the ServerDomain value in [EXCHANGEPAMEXCHANGESERVERS] SQL table to "intra.contoso.com" so the new URI will be "ex2016.intra.contoso.com"

Restart MAM Manager service to refresh.
