Exchange Server supportability matrix
The Exchange Server supportability matrix provides a central source for Exchange administrators to easily locate information about the level of support available for any configuration or required component for supported versions of Microsoft Exchange Server.
Release model
The following table identifies the release model for each supported version of Exchange.
In Exchange Server 2010 and earlier, each update rollup package (RU) is cumulative. An RU for Exchange Server 2010 includes all fixes for Exchange Server from all previous update rollup packages, so you only need to install the latest RU to apply all of the fixes that were released up to that point. However, individual updates or hotfixes for Exchange 2010 or earlier do not contain all previous fixes for Exchange Server. The updated files that are included in an individual update or hotfix include all updates that were applied only to those specific files by all previous updates, but any other files on Exchange Server will not be updated. For more information, see Exchange 2010 Servicing.
In Exchange Server 2013 or later, we changed the way we deliver hotfixes and service packs by using a scheduled delivery model. In this model, cumulative updates (CUs) are released quarterly (every three months). Each CU is a full installation of Exchange that includes updates and changes from all previous CUs, so you don't need to install any previous CUs or Exchange Server RTM first. For more information, see Updates for Exchange Server.
| Servicing release model | Exchange 2019 | Exchange 2016 | Exchange 2013 |
|---|---|---|---|
| Cumulative Updates (CUs) | Yes | Yes | Yes |
| Hotfixes (HFs) delivered separately | Yes | Yes | Yes |
| Security Updates (SUs) delivered separately | Yes | Yes | Yes |
Note
At this time, no additional CUs are planned for Exchange Server 2013 and Exchange Server 2016.
Support lifecycle
For more information about the support lifecycle for specific versions of Exchange, Windows Server, or Windows client operating systems, see the Microsoft Support Lifecycle page. For more information about the Microsoft Support Lifecycle, see the Microsoft Support Lifecycle Policy FAQ.
Exchange Server 2007 End-of life
Exchange 2007 reached end of support on April 11, 2017, per the Microsoft Lifecycle Policy. There will be no new security updates, non-security updates, free or paid assisted support options, or online technical content updates. Furthermore, as adoption of Microsoft 365 or Office 365 accelerates and cloud usage increases, custom support options for Office products will not be available. This includes Exchange Server, as well as Microsoft Office, SharePoint Server, Office Communications Server, Lync Server, Skype for Business Server, Project Server, and Visio. At this time, we encourage customers to complete their migration and upgrade plans. We recommend that customers leverage deployment benefits provided by Microsoft and Microsoft Certified Partners including Microsoft FastTrack for cloud migrations, and Software Assurance Planning Services for on-premises upgrades.

The following table identifies the web browsers supported for use together with the light (basic) version of Outlook Web App or Outlook on the web.
Note
Outlook Web App Basic (Outlook Web App Light) is supported for use in mobile browsers. However, if rendering or authentication issues occur in a mobile browser, determine whether the issue can be reproduced by using Outlook Web App Light in the full client of a supported browser. For example, test the use of Outlook Web App Light in Safari, Chrome, or Internet Explorer. If the issue can't be reproduced in the full client, we recommend that you contact the mobile device vendor for help. In these cases, we collaborate with the vendor as appropriate.

Microsoft .NET Framework
The following tables identify the versions of the Microsoft .NET Framework that can be used with the specified versions of Exchange.
Important
Versions of the .NET Framework that aren't listed in the tables below are not supported on any version of Exchange. This includes minor and patch-level releases of the .NET Framework.
If you're upgrading Exchange Server from an unsupported CU to the current CU and no intermediate CUs are available, you should first upgrade to the latest version of .NET that's supported by your version of Exchange Server and then immediately upgrade to the current CU. This method doesn't replace the need to keep your Exchange servers up to date and on the latest supported CU. Microsoft makes no claim that an upgrade failure will not occur using this method, which may result in the need to contact Microsoft Support Services.
To upgrade the .NET Framework on an existing Exchange Server, do the following steps:
Put DAG member servers into maintenance mode by replacing <ServerName> with the name of the server and running the following command in the Exchange Management Shell:
Set-ServerComponentState <ServerName> -Component ServerWideOffline -State Inactive -Requester MaintenanceStop all Exchange services. For example:
Use services.msc
Run the following Windows PowerShell command twice:
Get-Service *exch* | Stop-ServiceNote
We do not recommend using the Force switch in the command to stop all Exchange services.
Download and install the latest supported version of the .NET Framework as described in the tables in the next section.
Reboot the server after the .NET Framework installation is complete.
Install the latest available CU as described in Updates for Exchange Server.
For Exchange 2013, see Updates for Exchange 2013
Reboot the server after the CU installation is complete.
Verify that all Exchange services are in their normal start mode and started. For example:
Use services.msc
Run the following Windows PowerShell command:
Get-Service *exch*
Take DAG member servers out of maintenance mode by replacing <ServerName> with the name of the server and running the following command in the Exchange Management Shell:
Set-ServerComponentState <ServerName> -Component ServerWideOffline -State Active -Requester Maintenance

| .NET Framework 3.5 | Supported1 |
1 On Windows Server 2012, you need to install the .NET Framework 3.5 before you can use Exchange 2010 SP3.
2 Exchange 2010 uses only the .NET Framework 3.5 and the .NET Framework 3.5 SP1 libraries. It doesn't use the .NET Framework 4.5 libraries if they're installed on the server. We support the installation of any version of the .NET Framework 4.5 (for example, .NET Framework 4.5.1, .NET Framework 4.5.2, etc.) as long as the .NET Framework 3.5 or the .NET Framework 3.5 SP1 is also installed on the server.
Windows PowerShell
Exchange 2013 or later requires the version of Windows PowerShell that's included in Windows (unless otherwise specified by an Exchange Setup-enforced prerequisite rule).
Exchange 2010 requires Windows PowerShell 2.0 on all supported versions of Windows.
Exchange does not support the use of Windows Management Framework add-ons on any version of Windows PowerShell or Windows.
If there are other installed versions of Windows PowerShell or PowerShell Core that support side-by-side operation, Exchange will use only the version that it requires.
Microsoft Management Console
The following table identifies the version of Microsoft Management Console (MMC) that can be used together with each version of Exchange.
