"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You need to server Prerequisites

Make sure that the functional level of your forest is at least Windows Server 2003, and that the schema master is running Windows Server 2003 with Service Pack 1 (SP1) or later. For more information about the Windows functional level, see Managing Domains and Forests.

The full installation option of Windows Server 2008 with SP2 or later, Windows Server 2008 R2 RTM or later, or Windows Server 2012 must be used for all servers running Exchange 2010 server roles or management tools.

For all server roles other than the Edge Transport server role, you must first join the computer to the appropriate internal Active Directory forest and domain.

If you have multiple servers the install order is important:

Installation order is :
>  Internet facing CAS. then remaining cas server
> Hub server
> MB Server
> UM Server
> Edge Server

No, you don't need to put into maintenance mode.  Just download and install.

are you running exchange 2016?
if not, i wouldn't worry too much about it since that update fixes only 1 issue with EWS connections from exchange 2016

hi scott,

as per Andy Mlad above link, it requires to be on maintenance mode.

Phase 2: Upgrading Database Availability Groups to Exchange 2010 SP3 with latest RU (Start with Passive)

 1) Open Exchange Management Shell, browse to script folder and run below command
 .\StartDagServerMaintenance.ps1 -serverName servername

 Note: This script move all Exchange related component including database to another server.
 2) Disable the Forefront by using below command (It might ask you to stop few EXchange services)

 fscutility /disable

 3) Stop the OS Antivirus services and Monitoring Agent for Microsoft Exchange Server

 4) Verify Backups are completed.

 5) Run the SP3 and RU setup files using GUI or goto run setup /m:upgrade

 6) Reboot the server

 7) After reboot verify below logs for any error:
 Event Logs
 Setup Logs (C:\ExchangeSetupLogs)
 Services - All Exchange related services are running.
 Check IIS Settings are not changed.
 Check Authentication settings from EMC for OWA/OMA/ESW. If you find any change revert back to old.
 8) Enable Forefront Protection for Exchange. Command fscutility /enable (It might ask you to stop few EXchange services)

 9) Start OS Antivirus and Exchange Monitoring Agent Services
 10) .\StopDagServerMaintenance.ps1 -serverName servername

 11) Now use same steps on another server in DAG.

I understand...Here is a blog on maintenance mode and when/why you should use it.

I've always been able to schedule my Exchange upgrades when it won't affect the users and therefor never had to use it.
