Last updated on April 18, 2024
Microsoft Exchange is offered as both an online version, which is a Software As A Service (SaaS), and an offline, or on-premise version, known as Microsoft Exchange Server. The table below only lists the versioning of Microsoft Exchange Server.
Microsoft Exchange Server is an email and calendering server developed by Microsoft, usually deployed by organizations to manage user emails and events.
Support status guide
End of life (EOL) is the end of a product’s useful life. When a product reaches the end of its life cycle, the manufacturer no longer supports it. The following table explains the different phases of a product’s lifecycle. Testing status is when the product is initially released and EOL is when product support is no longer offered. The time between these two points is the support timeframe.
Testing
The software is not yet publicly available. It is in testing phase i.e., alpha, beta, release preview etc.
Active
The software is actively supported by the vendor.
Phasing Out
The software will soon reach its end of life. You need to look for upgrade or migration options. The software will automatically go into phasing out status 2 months before end of life.
End Of Life

Rather than following the semantic version scheme, Microsoft Exchange Server follows a different approach. It names the versions after its updates which can be a Cumulative Update (CU), a Security Update (SU), or an Update Rollup (UR).
After Exchange Server 2013, Microsoft stopped rolling out Service Packs (SP). Exchange Server 2016 and later only received CU and SU updates.
Additionally, Microsoft has no fixed cadence for updates and is published as needed. Even the major updates can go unplanned, as announced here by Microsoft.
At the moment, the next major update for the Microsoft Exchange Server has been scheduled for the second half of 2025.
