Hey guys! Ever needed to quickly figure out which version of Exchange Server you're running? PowerShell to the rescue! It's super handy for all sorts of Exchange tasks, and checking the version is one of the simplest. This guide will walk you through the different ways to check your Exchange version using PowerShell, making sure you’re always in the know. Whether you're troubleshooting, planning an upgrade, or just curious, knowing your Exchange version is crucial.

Why Knowing Your Exchange Version Matters

Understanding the Exchange version you're working with is super important for a bunch of reasons. First off, different versions of Exchange have different features. Knowing your version helps you figure out what capabilities are available to you. For example, some of the newer versions have better security features and improved integration with other Microsoft services. Secondly, it's essential for compatibility. When you're thinking about integrating Exchange with other systems or applications, you need to make sure they're all going to play nicely together. Different versions might have different requirements, so you want to avoid any headaches down the road. Thirdly, troubleshooting becomes a whole lot easier when you know your Exchange version. Error messages and solutions often vary between versions, so having the right info can save you a lot of time and effort. Finally, knowing your version is crucial for planning upgrades. You need to know where you're starting from to figure out the best path to the latest version. Each upgrade path has specific requirements and considerations, so this is definitely not something you want to overlook.

Prerequisites

Before we dive into the PowerShell commands, let's make sure you're all set. First, you'll need to have the Exchange Management Shell installed. This is usually installed along with Exchange Server, but if you're managing a remote server, you might need to install it separately. You also need to have the necessary permissions to run Exchange PowerShell commands. Usually, being a member of the 'Organization Management' role group will do the trick. If you're not sure whether you have the right permissions, you can ask your Exchange administrator. Also, it's a good idea to run PowerShell as an administrator. This will prevent any permission-related issues when running the commands. To do this, right-click on the PowerShell icon and select 'Run as administrator'. Double-check that you have network connectivity to your Exchange server. You won't be able to run the commands if you can't connect to the server. Lastly, make sure you know the hostname or IP address of your Exchange server. You'll need this to connect to the server using PowerShell. Got all that? Great! Let's move on to the fun stuff.

Method 1: Using Get-ExchangeServer Cmdlet

One of the easiest ways to check your Exchange version is by using the Get-ExchangeServer cmdlet. This command gives you a ton of info about your Exchange servers, including the version. To use it, first open the Exchange Management Shell. Then, just type in Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion. This command will list all Exchange Servers in your organization along with their names, editions, and versions. The AdminDisplayVersion field is what you're looking for to find the exact version number. If you have multiple Exchange servers, this command will show you the version of each one. This is super handy if you're managing a larger Exchange environment. You can also filter the results to find a specific server. For example, if you want to find the version of a server named 'MailServer01', you can use the command Get-ExchangeServer MailServer01 | Format-List Name, Edition, AdminDisplayVersion. This will only show you the info for that specific server. The Get-ExchangeServer cmdlet is a quick and easy way to get the Exchange version, and it's usually the first command you should try. It's simple, straightforward, and gives you all the info you need.

Example

Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion

This command displays the name, edition, and AdminDisplayVersion of all Exchange servers in your organization.

Method 2: Using Get-Command Cmdlet

Another method to check the Exchange version with PowerShell involves using the Get-Command cmdlet. This method is a bit more indirect, but it can be useful if you want to verify that the Exchange Management Shell is properly loaded and that the Exchange cmdlets are available. To use this method, open PowerShell and type Get-Command Get-ExchangeServer. If the Exchange cmdlets are loaded correctly, this command will display information about the Get-ExchangeServer cmdlet, including its version. The version information is usually displayed in the 'Version' field. If the command returns an error or doesn't display any information, it means that the Exchange Management Shell is not properly loaded. In that case, you might need to import the Exchange module manually. You can do this by running the command Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 (or the appropriate version for your Exchange server). This method is particularly useful when you're troubleshooting issues with the Exchange Management Shell. If you're having trouble running Exchange cmdlets, this can help you determine if the issue is with the Exchange Management Shell itself or with the cmdlets. It's also a good way to verify that you have the correct version of the Exchange Management Shell installed.

Example

Get-Command Get-ExchangeServer

This command shows the version of the Get-ExchangeServer cmdlet, which indicates the Exchange version.

Method 3: Checking the Registry

If you're feeling a bit adventurous, you can also check the Exchange version by looking at the Windows Registry. This method is a bit more technical, but it can be useful if you can't use the Exchange Management Shell for some reason. To do this, open the Registry Editor (type regedit in the Run dialog). Then, navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\Setup. In this key, you'll find a value named MsiProductVersion. This value contains the Exchange version number. Keep in mind that the v15 part of the key name might be different depending on your Exchange version. For example, for Exchange 2013, it might be v15, while for Exchange 2016, it might be v16. This method is a bit more risky because you're directly modifying the Registry. Make sure you know what you're doing before you start messing around with the Registry. It's always a good idea to back up the Registry before making any changes. Also, this method only works if you're on the Exchange server itself. You can't use it to check the version of a remote server. But, if you're in a situation where you can't use the Exchange Management Shell, this can be a useful alternative.

Example

1. Open Registry Editor (regedit).
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\Setup.
3. Check the MsiProductVersion value.

This shows the Exchange version number stored in the registry.

Method 4: Using the Exchange Admin Center (EAC)

For those who prefer a graphical interface, the Exchange Admin Center (EAC) provides a straightforward way to check your Exchange version. Log in to the EAC using your administrator credentials. Once you're in, look for the 'Servers' section, and then click on 'Servers' again. This will display a list of all Exchange servers in your organization. Click on the server you want to check the version for. In the details pane on the right, you'll see the Exchange version listed under the 'Exchange version' field. This method is super easy and doesn't require any PowerShell commands. It's perfect for those who are not comfortable using the command line. The EAC also provides a lot of other useful information about your Exchange servers, such as their health status, CPU usage, and memory usage. So, it's a good place to start when you're troubleshooting issues or just want to get an overview of your Exchange environment. Just keep in mind that you need to have the necessary permissions to access the EAC. Usually, being a member of the 'Organization Management' role group will do the trick.

Steps

1. Log in to the Exchange Admin Center (EAC).
2. Navigate to Servers > Servers.
3. Select the server.
4. View the Exchange version in the details pane.

Troubleshooting Common Issues

Sometimes, you might run into issues when trying to check the Exchange version using PowerShell. Here are a few common problems and how to fix them. First, if you're getting an error that says 'The term 'Get-ExchangeServer' is not recognized', it means that the Exchange Management Shell is not properly loaded. To fix this, try importing the Exchange module manually. You can do this by running the command Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 (or the appropriate version for your Exchange server). If that doesn't work, make sure you have the Exchange Management Tools installed on your machine. Second, if you're getting an error that says 'Access is denied', it means that you don't have the necessary permissions to run the Exchange cmdlets. To fix this, make sure you're running PowerShell as an administrator and that you're a member of the 'Organization Management' role group. If you're still having trouble, you might need to ask your Exchange administrator to grant you the necessary permissions. Third, if you're getting incorrect version information, it might be because the Exchange server is not properly updated. To fix this, make sure you've installed the latest Cumulative Updates (CUs) and Security Updates (SUs) for your Exchange server. You can download the latest updates from the Microsoft website. Finally, if you're still having trouble, try restarting the Exchange server. This can sometimes fix weird issues that are causing the version information to be displayed incorrectly. Remember to always test any changes in a non-production environment first before applying them to your production environment.
