Dear Experts

Please can someone assist me. I keep receiving these alerts from SCOM.

The server is virtualized running Windows 20089 R2 std with 4GB static memory assigned.

I have attached my page file settings.

Here is the alert I keep receiving:

4gb is way too small
mailbox role requirement is 8gb minimum (exchange 2013) so not surprised you are getting those errors

how many mailboxes?  what version of exchange?
i would start by increasing the memory to 8gb and go from there
if you still have errors, increase to 16gb though again, sizing partially depends on number of mailboxes

Hi Seth

The server only has 9 mailboxes on it.

Exchange version is Exchange 2010 SP3 RU11

even still, it's below the system requirements
i've done 4gb in a test environment and had a lot of issues with exchange services
i increased to 8gb and ran much better
with only 9 mailboxes, 8gb should make this go away
