Exchange News and Announcements – Microsoft Ignite 2020 Edition
Published Sep 22 2020 08:01 AM 184K Views

Today we are announcing that the next versions of Exchange Server, SharePoint Server, Skype for Business Server and Project Server will be available in the second half of 2021, and are only available with the purchase of a subscription license. Subscription entitles access to support, product updates, security and time zone patches.

Microsoft Office will also see a new perpetual release for both Windows and Mac, in the second half of 2021.

We will share additional details around the official names, pricing and availability of all these products later.

The Next Version of Exchange Server

Update 6/2/2022: for more details about the future of Exchange Server on-premises please see Exchange Server Roadmap Update.

The next version of Exchange Server will support in-place upgrades from Exchange Server 2019 for a period of approximately two years following release. This feature will allow the admin to easily upgrade existing servers running Exchange Server 2019 to the subscription-based codebase without needing to add servers or move mailboxes.

The next version of Exchange Server will continue to support side by side deployment and migration from earlier versions of Exchange as has been the case over the last few releases but we have increased the number of versions it can be installed alongside. Customers with Exchange Server 2013, 2016 or 2019 can install the next version of Exchange Server into their existing Exchange Organization.

We highly recommended that customers with existing Exchange Server 2013 or 2016 deployments and who expect to keep on-premises servers in the future should start planning and installing Exchange Server 2019 today. Once the next version of Exchange is released, they will then be able to perform an in-place upgrade to that version, making the move to 2019 the last major upgrade they will ever need to do.  

You can get more information on this announcement by watching the Exchange – Here, There and Everywhere on-demand session here. We will have more details on this change over the coming months.

The Exchange Server Mailbox Role Calculator

To assist in planning Exchange Server 2019 deployments, we have decided to once again make the Exchange Server Mailbox Role calculator available to download separately from the server code.

This is effective today, and the calculator is available to download here. We will continue to update the calculator as needed, and the timing of updates are not tied to Cumulative Update cycles.

The Hybrid Configuration Wizard and Multiple Tenants

It was announced today that the Hybrid Configuration Wizard (HCW) will now support and enable admins to configure multiple on-premises to cloud tenant configurations.

You can hear more about this in the Exchange, Here There and Everywhere session, and read more about this change in our dedicated Exchange Admin News blog post here.   

Opt-in to the New Modern Exchange Admin Center Experience

Exchange admins can now opt-in to the new and modern Exchange admin center simply by using a new toggle switch control in the top right corner of the legacy Exchange admin center. The new admin center will then appear within the same browser tab.

The modern Exchange admin center (EAC) has been in Public Preview since July 2020. We built the new modern experience to fit right in with the other Microsoft 365 admin portals. We’ve recently reached parity with the legacy admin interface and are now adding new features such as personalized dashboards, cross tenant migration and providing actionable insights. We have also invested in a better mobile experience for admins on the go. Try it today either by visiting or by opting-into it from the legacy portal.

Certificate-based Authentication for Exchange Online PowerShell V2

We are also announcing today the general availability of certificate-based authentication for the Exchange online PowerShell V2 module. This feature enables running unattended scripts without using resorting to Basic Authentication. Certificate based authentication provides admins the ability to run scripts without the need to create service-accounts or store credentials locally.

More details on the feature are available here.

Linux and PowerShell Core support for v2 PowerShell Module Preview

To help our admins we’re adding support for Linux and PowerShell Core to the Exchange Online v2 PowerShell module. You can also get more information about this change in our dedicated Exchange Admin News blog post here.

Cross-tenant mailbox migrations in Public Preview

Historically, when an Exchange Online admin needed to move mailboxes from one tenant to another, the typical way to do that was to offboard the mailbox from the source tenant and import it into the target tenant.

During Microsoft Ignite, we announced the Public Preview of a built-in tenant-to-tenant mailbox migration service that enables you to move mailboxes between tenants with minimal on-premises infrastructure dependencies (the new service eliminates some but not all on-premises components). The new cross-tenant mailbox migration service eliminates the need to offboard and onboard the mailbox, resulting in a faster and lower-cost migration. This is particularly beneficial for organizations undergoing mergers, acquisitions, divestitures, or splits.

Check out all the details in this blog post.

Plus Addressing in Exchange Online

Last year at Microsoft Ignite 2019 we announced we had plans to add Plus Addressing to Exchange Online, and today we confirmed it is now available worldwide.

The feature makes it easy for end-users to sign up for email lists using unique email address. This then makes it easy to create rules and spot where addresses have been leaked and are being mis-used.

This feature must be enabled by a tenant admin, and you can read more about it in our dedicated Exchange Transport blog post here.
