Line 1: Line 1:
 +======LAN Forward Warning: 452 (4.3.1 Insufficient system resources)======
 +If you get this message in VPOP3 it means that VPOP3 is trying to forward a message on to another mail server (probably Microsoft Exchange Server), and that other server is rejecting the message with the error **452 4.3.1 Insufficient system resources**
 +You will need to fix the problem on the Exchange Server, it may be due to lack of disk space.
 +One of our users reported that they ran CLEANMGR on one of the partitions of the Exchange Server and freed up some disk space to resolve the problem.
 +If this doesn'​t help, you may need to contact Microsoft'​s technical support for help with Exchange Server.
