Network problems are preventing the agent’s connection to the Microsoft Exchange Server.
Check PING times between the agent host server and all Exchange servers, noting the percentage of packet loss and whether the remote host responds.
Check DNS (FQDN) name resolution and try resolving the Microsoft Exchange Server name using NSLOOKUP and PING with the -a option.
Review the Windows event logs on Microsoft Exchange Servers for errors and/or warnings.
Check that all required services are started and running on Exchange servers.
Check that the require ports are open for the agent from the Exchange server to the Agent host server as detailed in the "SysReqAndAccessRights" documentation included with the product.
