Announced: improvements to Hybrid Publishing and Organization Configuration Transfer

Published Sep 26 2018 08:51 AM 18K Views

What just happened?

During a rousing presentation that was marked by wild cheers and standing ovations, we announced a few features designed to simplify hybrid Exchange deployments and speed onboarding to Exchange Online (EXO). The features we discussed focused on two key problems, hybrid administration and configuration as customers prepare to move to the cloud and the complexities and security blockers some customers face when publishing their on-premises environments. Let’s review.

Administration and Configuration

Back in June, we launched Organization Configuration Transfer (OCT). The idea is to take the configurations made in Exchange Server on-premises and transfer them to Exchange Online to reduce the burden of re-configuring all your settings before onboarding. Today we announced OCTv2, due out October 2018.

What does OCTv2 do?

First and foremost, seven additional objects have been added to OCT as part of v2.
OCT OCTv2 (coming soon!) - now released
  • Active Sync Mailbox Policy
  • Mobile Device Mailbox Policy
  • OWA Mailbox Policy
  • Retention Policy
  • Retention Policy Tag
  • All OCTv1 objects
  • Active Sync Device Access Rule
  • Active Sync Organization Settings
  • Address List
  • DLP Policy
  • Malware Filter Policy
  • Organization Config
  • Policy Tip Config
But the real difference in v2 is how we deal with object conflicts. In OCTv1, we run a bunch of new-* commands and when we find an object on-prem that matches and object with the same name in the cloud, we simple skip over it. As part of v2, if an object with the same name already exists both on-premises and online, you can now choose to either overwrite the values of the objects in EXO or keep them as is. And, just in case you overwrite the cloud settings and didn’t mean to, we’ve provided a rollback script to undo those changes.

What are the Exchange Server Versions supported?

OCT supports Exchange Server 2016, 2013 and 2010. OCT requires the latest cumulative update or update roll-up available for the version of Exchange you have installed in the on-premises organization. But if that’s really too much of a burden, the immediate previous release is also supported. You want to run any other CUs or RUs, you’re out of luck. Exchange Server 2019 will be supported once it reaches GA.

Hybrid Publishing

To establish a hybrid Exchange environment, customers must publish their on-premises environments. This includes, but is not limited to, adding external DNS entries, updating certificates, and allowing inbound network connections through your firewall. Over time, we’ve learned of two consistent problems here, (1) this is hard for some customers. The number of support cases asking for help in these areas tells us that. And (2) some customers, really their security wonks, do not want to publish their on-premises environments to the internet. The Microsoft Hybrid Agent Today, we introduced the world to the Hybrid Agent. Put simply, the goal of the Hybrid Agent is to fix those customer problems. Now, when running the Hybrid Configuration Wizard (HCW) you are presented with the option to use Exchange Modern Hybrid Hybrid1 This will install an agent, built on the same technology as Azure Application Proxy, this will publish your Exchange on-premises environment to EXO without requiring any of the changes customers have struggled with. Hybrid2 V1 of the Hybrid Agent will support the core scenarios of mailbox moves and free/busy for your hybrid deployment and is in private preview now. We’re focused on getting to public preview and GA as quickly as possible. In the meantime, we’re also working on additional scenarios we can support with the Hybrid Agent.

What’s next?

Well, if you missed the session at Ignite, go back and watch the replay (when available). Then come back here and stay tuned for updates. Kavya Chandra, Georgia Huggins
