For up-to-date information on Hybrid Configuration Wizard steps, please see Microsoft Docs.The Exchange hybrid team has been working hard over the past year getting the 3rd version of the Hybrid Configuration Wizard (HCW) ready. This new version is called the Microsoft Office 365 Hybrid Configuration Wizard. This article tells you what’s new and shows you how to run the wizard. We also explain the various issues that have been addressed with the new Wizard, and touch on some of the telemetry we pull with every run of the wizard. We think this new wizard has enough of the old to reduce the learning curve while adding plenty of enhancements to make your hybrid deployment as friction free as possible.
Solution: The new HCW will download the latest version every time it is run, therefore providing the latest and improved experience. As soon as we make changes to, or fix any issues in the HCW, customers will see the benefits immediately.
Solution: Again, every time you attempt to run the HCW we will ensure you have the latest version. This version will of course go through its rounds of validation, but it is in no way tied to the releases of a CU. No more waiting months for fixes!
Solution: We have built in the capability to allow customers who are on “first Release” and any other customers we specify (for example TAP customers) to see the latest version of the HCW. Often the latest release and the production release will be the same version, but we do have the ability to pilot versions of the HCW as needed.
Note: If you want to opt out of uploading the Hybrid logs you can do that by using the registry key below on the machine were you are running the HCW from: 1. Navigate to the following location in the registry, create the path if needed: Exchange 2016: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v16\Update-HybridConfiguration Exchange 2013: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\Update-HybridConfiguration 2. Create REG_DWORD “DisableUploadLogs” with value 1
Solution: While simple, moving forward we are only going to copy the part of the string that is needed from the “copy link” option in HCW, which should lead to less issues with incorrect TXT strings.
Solution: To resolve this we created a new external endpoint in the service that will perform the DNS lookup for the TXT record and only try to federate the domain if the record is correct or if that new service endpoint cannot be found. The logic for this is as follows:
ERROR: Updating hybrid configuration failed with error 'Subtask Configure execution failed: Configuring organization relationship settings. Execution of the Set-WebServicesVirtualDirectory cmdlet had thrown an exception. This may indicate invalid parameters in your Hybrid Configuration settings. Unable to access the configuration system on the remote server. Make sure that the remote server allows remote configurationSolution: We have resolved this issue in the new HCW using the -ADPropertiesOnly option with Get-WebServicesVirtualDirectory. This changes things so the HCW reads the MRS settings using a local directory call instead of waiting for a response from every server in the environment. This change along with a few others in this area, makes the process take around 15 minutes instead of 8 hours (your deployment times will vary) in these large environments. This is just one example of the type of cleanups we did in the HCW to improve the reliability and speed of the configuration tasks.
