You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Transport Service" and "Edge Transport server" entries in the Mail Flow Permissions topic.
By default, anti-spam features aren't enabled in the Transport service on a Mailbox server. Typically, you only enable the anti-spam features on a Mailbox server if your Exchange organization doesn't do any prior anti-spam filtering before accepting incoming messages. For more information, see Enable Anti-Spam Functionality on a Mailbox Server.
You can't use the Exchange admin center (EAC) to perform this procedure. You can only use the Shell.
For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard Shortcuts in the Exchange Admin Center.
Run the following command:
Set-TransportService <ServerIdentity> -AgentLogEnabled <$true | $false> -AgentLogMaxAge <dd.hh:mm:ss> -AgentLogMaxDirectorySize <Size> -AgentLogMaxFileSize <Size> -AgentLogPath <LocalFilePath>
This example sets the following agent log settings on the Mailbox server named Mailbox01:
Sets the location of the agent log files to D:\Anti-Spam Agent Log. Note that if the folder doesn't exist, it will be created for you.
Sets the maximum size of an agent log file to 20 MB.
Sets the maximum size of the agent log directory to 400 MB.
Sets the maximum age of an agent log file to 14 days.
Set-TransportService Mailbox01 -AgentLogPath "D:\Anti-Spam Agent Log" -AgentLogMaxFileSize 20MB -AgentLogMaxDirectorySize 400MB -AgentLogMaxAge 14.00:00:00
