My friend has the below
** Exchange 2010
** Windows 2008 R2, will upgrade soon
shows the minimum required physical memory should be 20GB for 100 mailboxes, but he has 150 mailboxes, with memory almost 100% used which is normal for Exchange
1. Do you think he should really have 30+ GB of memory for 150 mailboxes ?
2. How can I find when Exchange needs MORE memory since I was told Exchange 2010 always runs at 100%, even after adding more memory ?
