Error shown under Exchange PowerShell while installing the agents manually -
The TransportAgentFactory type "Symantec.MailSecurity.Server.TransportAgent.SMSMSERoutingAgentFactory"
doesn't exist. The TransportAgentFactory type must be the Microsoft .NET class type of the tranport agent factory.
Microsoft Exchange 2010 RollUp 8 installation failed at some point and causes failure to load/install SMSMSE transport agents.
The issue is not product related but environment issue instead.
One known workaround is to Install
Microsoft Exchange RollUp 7 instead. However, i
t is recommended to contact Microsoft Support for workaround / solution.
