Remote Desktop Services on Server 2012R2 Role Fail

RDVH is based on Hyper-v so you need to install this role first. if you are running  ESXi and your Server is inside a VM, you need to enable VMware  nesting on your Virtual machine which is disable by default in order to be able to install Hyper-V on your VM. What you need to do is adding a couple of line of configuration in VMX file in your VM's file in appropriate ESXi DataStore. to do that, shutdown your machine, delete it from ESXi inventory, browse your data store  which contains your vm's files, locate vmx file of your vm, download it to your desktop, open it with wordpad and add these to lines to the end: 

vhv.enable = "TRUE"

hypervisor.cpuid.v0 = "FALSE"

save the file and put it back to the same location of  datastore you downloaded before. then put back youre vm to the ESXi inventory and you are ready to go. power on your vm and you will see that you are able to install Hyper-V roll on your machine.

Comparing Search-Mailbox and Compliance Search Actions

Comparing Search-Mailbox and Compliance Search Actions

Table 1 summarizes the functionality available in Search-Mailbox and purges executed with compliance search actions. Both have their unique characteristics: compliance searches are faster and can process more mailboxes in a single operation but are limited to what they can remove from a mailbox. Search-Mailbox can focus on Recoverable Items or ignore a mailbox’s archive, while compliance searches can focus on a single target folder. The biggest difference is that Search-Mailbox can copy items to a target mailbox when it removes them from other mailboxes. You can export items with a compliance search, but you must do this separately and before you remove anything.
