4.3.1 Insufficient System Resources on Exchange 2007
Posted on 2011-09-08
My client has been reporting intermittent email flow when receiving email. They will go for stretches of hours without receiving email. I checked the boards and found suggestions on telneting to the server and using the command MAIL FROM:firstname.lastname@example.org. This returns the 4.3.1 Insufficient System Resources message.
I edited the EdgeTransport.exe.config file and disabled Back Pressure setting and changed the Queue path to the D drive and restarted the Transport service as well as the server. In both cases, the email is not flowing and I still receive the above message when telneting.
They are using SBS2008 server.
Any suggestions are appreciated.
