How to run the HCW in your Exchange 2010 environment

A few common questions answered:

Why did we update the Office 365 Hybrid Configuration wizard for Exchange 2010?

The new Office 365 Hybrid Configuration wizard, which was released a few months back for Exchange 2013 and 2016, has allowed us to really understand the Hybrid Configuration experience. We can see if there was a failure or slow experience, what the issue was, and we collect and act on any feedback that is provided. All of this telemetry allows us on the engineering side to prioritize and address the issues that need to be addressed quickly. Since we have included Exchange 2010 support in this wizard, now all hybrid customers will see these benefits.

To find out more about the benefits of running the new HCW you can review our previous blog were we introduced the Office 365 Hybrid Configuration wizard.

What Update needs to be installed for the new wizard to work against Exchange 2010?

All you need is Exchange 2010 service pack 3, we do not check for the existence of any rollups. However, newer rollups will have plenty of code and security fixes, so (while not required for HCW to complete) I would make sure you try to stay current. To see the list of the latest updates for each version of Exchange go here.

Can I run the new wizard even though I have already run the old HCW in my environment?

Yes, the new wizard will run even if the old wizard completed or partially completed in your environment. If there is no reason for you to update your old configuration you do not need to run the wizard now, but the next time you have an update to make you should use this new experience.

Is this new hybrid wizard different than the Exchange 2013/2016 hybrid wizard that was announce a few months back?

No, this is the same wizard. However, the wizard has been updated to support the unique configurations that are required for Exchange 2010 Hybrid environments. For example, in a 2010 Hybrid environment you need additional Remote Domain configurations for mail flow features. These Exchange 2010 Explicit configurations needed to be added.

Is this new wizard considered BETA or test software?

No, in fact this is the supported way to configure hybrid moving forward.


Do you want to shave hours off of your hybrid deployment, have a more stable environment, and want to simplify the hybrid configuration experience? Stop using the old Hybrid Configuration wizards and use the new Office 365 Hybrid Configuration wizard instead. If you have an issue or any feedback on the wizard, provide it, there is a feedback button on every page in the wizard and we are eager to read and act on it.

Spread the word to anyone that you know who has run or is getting ready to run the Hybrid Configuration wizard.
