Exchange Server 2016 and Dynamics 365 PSA to Reach End of Support in 2025 — Plan Your Migration Now

Microsoft has revealed that Exchange Server 2016 and Dynamics 365 Project Service Automation (PSA) will reach the end of their support lifecycle in 2025. While Exchange Server 2016 already reached end of mainstream support in October 2020, its extended support phase will end on October 14, 2025.

Microsoft will stop providing technical support, bug fixes, and security patches for Exchange Server 2019. The next version of Exchange Server is slated for release in the third quarter of 2025. For those maintaining on-premises environments, Microsoft recommends upgrading to Exchange Server 2019, with an in-place upgrade option to Exchange Server Subscription Edition (SE) available once it is released.

How to prepare for the end of support for Exchange Server 2016

Microsoft has outlined steps for administrators to transition from Exchange Server 2016 to Exchange Server 2019. This involves updating third-party applications, reconfiguring client access services, and migrating all Exchange 2016 mailboxes to the newer version.

After completing the migration, Microsoft recommends placing Exchange 2016 servers in maintenance mode for one week to check for any issues. If no problems arise, administrators can proceed with uninstalling the legacy servers. They will need to perform some post-uninstallation tasks depending on the organization’s operational requirements. These include removing the Exchange 2016 accounts from Active Directory, deleting Exchange 2016 servers as targets for other services, removing Exchange 2016 name records from DNS, and more.

Microsoft to kill off Dynamics 365 PSA in March 2025

Microsoft has announced that support for Dynamics 365 Project Service Automation (PSA) will end on March 31, 2025. This tool helps organizations manage and deliver project-based services, including project planning, estimate creation, and work schedule management.

“Beginning March 31st, 2025, Microsoft will no longer support PSA on commercial cloud environments. There will not be any feature enhancements, updates, bug fixes, or other updates to this offering. Any support ticket logged for the PSA commercial cloud will be closed with instructions to upgrade to Dynamics 365 Project Operations,” said Rupa Mantravadi, Principal Group Program Manager, Dynamics 365 Project Operations.

Microsoft urges commercial customers to upgrade from Dynamics 365 Project Service Automation to Dynamics 365 Project Operations. This new service offers various capabilities like AI-powered features, advanced scheduling, project budgeting, and integration with the Microsoft Project Web app.
