I have a customer with an SBS 2011 server running Exchange 2010, he is having mailboxes quarantined and I suspect possible server performance issues, threads taking too long. It is a small Fujitsu server with 16Gb RAM with a pair of mirrored hard drives. This means that the tmp and temp folders are on the same drive as the operating system.
Question, is it OK to add an EXternal USB hard drive and make the paths to the temp folders on the external drive to see if it helps?
Or would that not work?
