Hi
I installed new SBS2011 and it was working for just one day .
But after one day we did not receive any emails then I restart exchange transport service and everything fixed. Unfortunately it happens several time .
This is a virtual server on ESXI 5.1 . There is just AVG on the server . 10 G memory 2 core CPU and 120G(SSD) hard drive for OS and 40G hard drive (SSD) for 8 mail boxes .
Server is full updated .
Looking for any advice.
