Planning for the Microsoft Exchange Online UM Deadline and Exchange Server 2019

 In Blog, General, Technology, Unified Communications, Voice

Microsoft has made two announcements affecting Unified Messaging (UM), disrupting organizations across a variety of markets. Since UM is a mission-critical component to any organization’s communications, it’s important to get a clear understanding of what the recent Microsoft announcements mean, who they will impact, and how. Let’s take a closer look.


Announcement #1 – Exchange Online UM Deadline

As of December 1, 2019, Microsoft is ending support for Session Border Controllers (SBC), connecting on-premises PBX phone systems to Exchange Online UM/Office 365. Customers who want to keep using their on-premises PBX – Avaya, Cisco, Mitel, NEC (you name it), will have to find an alternative unified messaging solution.


Announcement #2 – Exchange Server 2019

Say goodbye to Unified Messaging in Exchange Server 2019. Microsoft has released the preview to their Exchange Server 2019 and with that, announced that UM will no longer be supported. Unified Messaging has been an essential feature of the software since it was first introduced in Exchange Server 2007. If customers want to upgrade to Exchange 2019 and continue to use unified messaging, they will need to find a new UM solution.


Who Does This Impact?

These announcements are signs that Microsoft is starting to put pressure on customers to commit to the entire Office 365 suite and other Microsoft cloud offerings. Your organization needs to decide what technology you want to consume from the cloud, in the near and long-term future.

For organizations wanting to keep using their on-premises PBX and continue to use UM, XMedius is here to help.

Your organization will need to find a new UM solution if you use:
• Exchange Online UM and want to keep using your on-premises PBX (Avaya, Cisco, NEC, Mitel, etc.)
• Exchange Server for UM connected to an on-premises PBX and plan to upgrade to Exchange Server 2019 in the future
• Skype for Business Server and want to continue to use UM on-premises
