Run the Hybrid Configuration Wizard (HCW)
In the previous article, we did install and configure Azure AD Connect to sync identities between on-premises and Office 365. In the next task, we will install and run the Hybrid Configuration Wizard (HCW). The HCW will ensure that we have an Exchange Hybrid deployment between two Exchange environments.
Table of contents
Hybrid Configuration Wizard progress
The general phases of the hybrid deployment configuration process are:
- Verifying prerequisites and performing topology checks
- Testing account credentials
- Making hybrid deployment configuration changes
Before you start
It’s good to know that you can configure one or more Exchange Servers for Hybrid. Open port 25 and 443 on the Exchange Servers. These Exchange Servers need to be Client Access Servers (CAS). In this example, we will use Exchange Servers EX01-2016 and EX02-2016 for Hybrid.

Exchange Servers up to date
Make sure that the Exchange Servers are on the latest version. Run Exchange Management Shell as administrator and run the Get-ExchangeServer cmdlet to check the Exchange Server versions. Always keep the Exchange Servers up to date.
[PS] C:\>Get-ExchangeServer | Format-Table Name, Edition, AdminDisplayVersion
Name Edition AdminDisplayVersion
---- ------- -------------------
EX01-2016 Enterprise Version 15.1 (Build 2176.2)
EX02-2016 Enterprise Version 15.1 (Build 2176.2)Enable MRS proxy
If you don’t complete this step before running the HCW, the HCW will enable MRS proxy. However, we recommend that you complete this step before running the HCW to ensure the IIS cache has time to clear before HCW validates the endpoint.
Run the Get-WebServicesVirtualDirectory cmdlet to check if MRS proxy is enabled.
[PS] C:\>Get-WebServicesVirtualDirectory | Format-Table Server,MRS*
Server MRSProxyEnabled
------ ---------------
EX01-2016 False
EX02-2016 FalseIf it’s not enabled, enable the Mailbox Replication service (MRS) proxy on the EWS virtual directory.
[PS] C:\>Get-WebServicesVirtualDirectory -ADPropertiesOnly | Where {$_.MRSProxyEnabled -ne $true} | Set-WebServicesVirtualDirectory -MRSProxyEnabled $trueAnother way to enable MRS proxy is with Exchange Admin Center.
Go to servers > virtual directories. Select All Servers and select EWS to filter on that type. Double-click on the EWS virtual directory in the list view.
Click on general and Enable MRS Proxy endpoint. Do this for both the Exchange Servers.
Remove previous Hybrid Configuration Wizard version
Go to Programs and Features in Control Panel and verify that a previous Hybrid Configuration Wizard is not already installed. If it is, uninstall it.
In the next step, you will download and install Office 365 Hybrid Configuration Wizard step by step.
Download Hybrid Configuration Wizard
You can run the Hybrid Configuration Wizard from other Windows Servers or a workstation. We recommend to sign in on an Exchange Server and install the HCW directly on the Exchange Server.
Start Microsoft Edge and copy-paste the link https://aka.ms/HybridWizard (Microsoft). If you use other web browsers, it might not work as expected. That’s why we recommend using Microsoft Edge.
Note: If you don’t get the HCW install window, read the article Office 365 Hybrid Configuration Wizard can’t start.
Install Hybrid Configuration Wizard
After you download the Hybrid Configuration Wizard setup, click Install.
The Microsoft Office 365 Hybrid Configuration Wizard installer is running.
Run Hybrid Configuration Wizard
After downloading and installing, the first screen of the wizard shows up. Click next.
The Hybrid Configuration Wizard will detect the optimal Exchange Server. Click on next.
Change the on-premises Exchange administrator account credentials if you want. In our example, we will keep the same user that’s logged in. Click sign in and enter the Office 365 Exchange Online Account. Click next.
It will gather both accounts’ information and check if it can connect to Exchange on-premises and Exchange Online. Click next.
If it fails, read the article Hybrid Configuration Wizard fails to connect.
Choose Full Hybrid Configuration and select the checkbox Organization Configuration Transfer.
Select Use Exchange Modern Hybrid Topology. Click next.
Do you want to keep mailboxes on-premises? Choose Exchange Classic Hybrid Topology because you want to configure Hybrid Modern Authentication in Exchange on-premises.
Note: Hybrid Modern Authentication with Exchange Modern Hybrid Topology (Hybrid Agent) is not supported.
Go to Active Directory Users and Computers. Create a service account svc-hybridmigrations. Make it a member of the group Organization Management.
Exchange Online will use the credentials to connect to your on-premises Exchange Server to move mailbox data to the cloud. It means that it will go to need some special privileges. If you enter your administrator account credentials here, it will work. But, it’s a member of the domain admins group and a powerful account for such a task.
Instead, you can create a special service account and add it to the Organization Management group. Fill in the credentials that you created in the above step. Click next.
The Hybrid Agent setup will start to download, install, register, and validate the Hybrid Agent. Click next.
Select Configure my Client Access and Mailbox servers for secure mail transport (typical). If you have an Edge Transport server, use the second option. Click next.
Choose both Exchange Servers for the receive connector. Click next.
Choose both Exchange Servers for the send connector. Click next.
Select the certificate. Click next.
If you don’t have a valid certificate, you can’t proceed further.
Fill in the DNS name that represents your on-premises Exchange Organization for hybrid mail flow. This determines where Exchange Online Protection will connect to in order to route email from the cloud to the on-premises organization. Click next.
Choose Review the objects before transferring from on-premises to Exchange Online. Click next.
Click on the objects and check what’s different. Look closely and make a decision. We will skip these conflicts and leave them the way they are. Click next.
Click update and wait for the Hybrid Configuration Wizard to run.
You can get an error HCW8077 and HCW8092. Click retry.
If the retry button doesn’t work and you still get an error, read the article Tenant organization is dehydrated.
Click update.
Congratulations! The Exchange Hybrid Configuration is a success. The hybrid services are now configured between Exchange Online in the Office 365 tenant and the on-premises Exchange environment. Click close.
Verify Hybrid Configuration Wizard installation
Go to Programs and Features and check that there is new software installed.
By default, the hybrid configuration log location is on the on-premises Mailbox server at:
%UserProfile%\AppData\Roaming\Microsoft\Exchange Hybrid Configuration
You can always rerun the Hybrid Configuration Wizard whenever you make any changes to the environment.
In the next article, we will look at the tools to manage Exchange Hybrid.
Conclusion
You learned how to download, install and run the Hybrid Configuration Wizard. After running the Hybrid Configuration Wizard, there is a coexistence between the on-premises environment and Exchange Online.

Hi,
Thank for this awesome article.
I am receiving a Hybrid agent setup failing on the “Validating Hybrid Agent for Exchange usage error”.
Guidance to resolve this issue would be highly appreciated.
I cannot complete the HCW after i executed your MonitorExchangeAuthCertificate.ps1 script to renew the server auth certificate.
It stuck at the task “configure email flow” with error message HCW8099 – command not recognized. Please verify you have the correct Management Role assigned to your account.
In the log file i see this: “cmdlet New-InboundConnector is not present in the role definition of the current user”.
I checked the Organization Management Role but the user is included.
Do you have any ideas maybe?
Just want to thank you Ali for your most valuable articles, itis really helpful for me, you almost covered all aspect of Exchange servers.
Hi,
Very nice article
If I’m running a 2019 on premise exchange environment and only want to run the HCW as a pre requisite for enabling modern auth is there anything else I need to do differently other than select the Classic hybrid topology option? At the end do I still transfer the objects online ?
Many thanks
Is it okay to re-run Hybrid Configuration Wizard when we’re having issues? We are currently facing issues all of a sudden about Free-Busy schedule between 2 environments. Both environments used to be able to see each other’s Free-Busy schedule but a few days ago, our on-prem users are not able to see our Cloud user’s free-busy sched. Whenever an onprem user access cloud calendar, there’s a yellow diamond with red exclamation captioned “could not be updated”.
Any thoughts?
Yes, it’s completely fine to re-run the Hybrid Configuration Wizard.
There are different reasons why calendar sharing is breaking between on-premises and cloud. Here is an article that you can go through: Exchange Hybrid calendar sharing not working.
If you have any proxy involved on your Exchange server, make an exception for *.windows.net to be able to run this.
Hello,
I have 2 Exchange 2016 servers installed on Windows 2012 R2.
I want to install a new Exchange 2016 cluster on Windows 2016 and migrate mailboxes to it.
I don’t have newer CALs and I want to get rid of Windows 2012R2.
I have a hybrid setup but all mailboxes onsite (local)
When installing new Exchange 2016 servers in my organization, do I have to install and configure Microsoft Office 365 Hybrid Configuration Wizard on each of them or is it was done once on one server for the entire organization?
How can I verify the current configuration on installed servers (Windows 2012 R2)?
I didn’t install it.
Regards π
Daniel
Hi,
Our exchange 2019 is running on a windows core server. I installed the Hybrid configuration on another server to run the wizard.
The wizard has run without error. But I cannot see the ‘Microsoft hybrid service’ as being installed.
When I look at the ‘Hybrid’ page on the on-premise admin center. I cannot see the configuration.
When I run ‘Get-hybridconfiguration’, I have results.
Do you have any ideas?
Tannks
The “Hybrid” page in on-premises Exchange admin center will stay empty, and you will not see any details there.
Running the Get-HybridConfiguration cmdlet is the correct way.
Hi Ali,
I need to migrate an onpremise exchange to the cloud, but we want to use teams. Which type of migration should I use, classic or modern?
Thank you very much for your tutorials
You should choose Exchange full Classic Hybrid deployment.
Modern Hybrid support is limited to Free/Busy and will not provide calendar integration from Teams to mailboxes on-premises.
Hi Ali,
First of all, over time, I found valuable and useful info on your site.
Straight to the point⦠We have an exchange classic hybrid organization, in on prem we have 8 exchange servers 2013 mbx&cas and 2 edge servers. We are planning to add 2 more servers mbx&cas to store journaling mailboxes. We do not intent to change the mailflow in any way The question is do we have to run again Hybrid config wizard ?
Hi Cristian
I was reading your question and i am thinking like why you have the hybrid setup at this point. Do you have mailboxes in the exchange365 environment or is all on-prem ?
The hybrid config wizard wants to know your primary on-prem server and some exchange configuration and routing. I guess the routing is now central configured on the on-prem server ?
if that’s the case I don’t think you need to run the wizard again.
If you change or upgrade your on-prem servers then it would be a good practice to run the EHW again.
but hopefully Ali will ready your post and give you a straight answer.
First of all, a very good article as always!
i am running into the following error and can not find any on the internet about this issue. I hope you all have any suggestion …
Its a hybrid wizard issue running for Exchange 2016 CU22
Transport organisation config is needed for the teams calanders en contacts.
Cheers

Hello Ali,
thank you for your courses, you re the best π
In this example, we will use Exchange Servers EX01-2016 and EX02-2016 for Hybrid Servers.
My question is, where did you actually select or define EX01 and EX02 as Hybrid Servers ?
By “Receive-Send Connector Configuration” section or not ?
If we have 3 or 4 On-Oprem Exhange Servers with different versions, could we select as Hybrid Server only the newest versions of Exchange-Servers ? If yes where could we define this ?
Thanks for your advices.
Hi Emre,
That’s correct.
So you will select the newest Exchange Server versions from the Receive/Send Connector configuration.
After running the Hybrid Configuration Wizard, you can check its configuration:
1. Run Exchange Management Shell as administrator
2. Run the below command:
Note: If the Exchange Server is not yet licensed, you choose it in the first step. So it will download and install a free Exchange Hybrid license. Suppose your Exchange Server is already licensed; you select that Exchange Server (shown in this article).
Hello Ali,
How are you?
Very good content. Taking advantage of the opportunity, you have already experienced the error HCW8099 – Command not recognized – Please verify you have the correct Management Rol assigned to your account?
Get-OrganizationRelationship
which port to authorize for HCW in dmz or very protected environnement pleasee
Thank you so much, your courses is incredible.
I tried to run HCW today, I need to use Classic Full on my client, but the installer doesn’t show the option screen for Classic or Modern, it’s the only screen that doesn’t appear.
I tried it on my end, and the Hybrid Topology option appears.
Checking the log I found:
Hybrid Connector Availability: False, Reason: Previous Migration Endpoint found with standard on-premises configuration.
I searched on local servers in Exchange Powershell with Get-MigrationEndpoint but didn’t find anything, I connected to 365 with Connect-ExchangeOnline and found the old Endpoint, I removed it (Remove-MigrationEndpoint -Identity identity-name) and now I’ve successfully finished the wizard π
hi there,
is it neccessary to configure Exchange Hybrid option within the AzureAD Connect first
or will it be just ok to run the wizzard as you mentioned here?
thanx for an advise..
kind regards
juergen
Is the modern hybrid still not supported for hybrid modern authentication?
Only Exchange Classic Hybrid Topology (Classic Full) supports Hybrid Modern Authentication.
getting this same error for duplicate.
there is nothing in enterprise apps in azure.
we want to use the modern
same external/internal url
Hi Ali,
Just wanted to start by thanking for all your document and so easy to follow! You save my butt a couple time. I was wondering if you could assist migrating from MX 2010 SP3 (has not had any release update installed on the original version for SP3) to Microsoft 365. Thank you in advanced!

Remove all migration batches and rerun the Hybrid Configuration Wizard (HCW).
Hi, I’m trying to setup 2 Exchange hybrid into single M365 tenant. And I have the same error like JKYU.
1st Exchange is already setup and working, but on the 2nd hybrid wizard end with this same error.
What happend if i delete migration batches and run wizard again, it will delete the 1st endpoint?
I want to keep both endpoints.
Thank you.

What does this mean I have a duplicate URL. Yes my internal and external URL are the same. They are can be. You instructions for setup even show that. Can you tell me what else to look for?
You get the Hybrid Agent registration error because you already have another Enterprise App published with the same URL.
The best way is to rerun the Hybrid Configuration Wizard and select “Use Exchange Classic Hybrid Topology” instead of the “Use Exchange Modern Hybrid Topology”. This way, you will not get this error.
We are also getting that error. Do you know of a way to check what Enterprise App is published with that same URL? Thanks for your help.
Is there way to figure out which Enterprise App is published with the same URL?
