Fix issue with Azure AD/Office 365 sync hogging CPU resource on Server 2016 domain controller

I have a Server 2016 Active Directory domain controller installed within a Server 2016 Hyper-V virtual machine that runs the Azure AD/Office 365 sync utility.

There is a constant issue where this Azure AD/Office 365 sync utility "Microsoft Online Reporting MonitoringAgent.Startup" utility consumes all of the CPU resources on this virtual server (see the screenshot).

I understand that this might be related to a .NET bug that Microsoft hasn't fixed yet.

All updates are installed on this Server 2016 server, its base server, and all other Hyper-V virtual servers.

The Hyper-V base server and all virtual machines are running on Solid State drives. The base server and all of the other virtual servers are operating just fine and don't have this issue with CPU utilization.

Currently, there are 4 virtual CPUs assigned to this virtual server (out of a total of 32 physical CPUs). It doesn't matter how many virtual CPUs I assign to this virtual server, this issue continues to occur when I have assigned 8, 12, or 16 virtual CPUs.

What can be done to fix this issue?

Above is correct, came across this issue also with a customer. Need to update to latest version either by the website or turning on automatic upgrade azure connect settings..

What are the steps to turn on "automatic upgrade azure connect settings"?

I would rather that this upgrade be done automatically and that all future upgrades be done automatically without me having to do them manually.

Please provide me with the exact steps on how to do this.

Alright, I have set it to Enabled.

Now how long will it take until it performs the first upgrade?

Is there any way I can make it perform the first upgrade right away instead of having to wait?

How can I determine what version I am running now?

What is the most recent version I can upgrade to?
