The Outlook version number is visible under File > Office Account > About Outlook. Knowing how to find out what version of Outlook I have is essential for troubleshooting, installing add-ins, or checking compatibility with email servers. This guide will walk you through every method to identify your Outlook version quickly and accurately.
How To Find Out What Version Of Outlook I Have
This is the most direct method and works for most modern versions of Outlook (2013, 2016, 2019, 2021, and Microsoft 365). You can find the exact version number, build number, and even the update channel in just a few clicks.
Step-By-Step: Using The File Menu
- Open Microsoft Outlook on your computer.
- Click the File tab in the top-left corner of the ribbon.
- In the left-hand menu, select Office Account (or Account in older versions).
- Look for the About Outlook button on the right side of the screen. It is usually a blue link or a small box.
- Click About Outlook. A new window will pop up showing the full version number.
The version number looks something like “Version 2302 (Build 16130.20218 Click-to-Run)”. The first part (2302) is the year and month of the update. The build number is more specific for technical support.
If you see “Microsoft 365” or “Office 365” in the title bar, you have a subscription-based version. The version number changes frequently with updates.
Alternative Method: Using The Help Menu (Older Versions)
For Outlook 2010 or earlier, the File menu method might not work. Instead, use the Help menu. Click Help in the top menu bar, then select About Microsoft Outlook. A dialog box will appear with the version info.
In Outlook 2007, you can also find the version by going to Help > About Microsoft Office Outlook. The version number is displayed prominently.
Checking Outlook Version In Windows Settings
If Outlook is not opening correctly, you can still find the version from Windows itself. This method works for all Outlook versions installed via Microsoft 365 or standalone Office suites.
Using The Installed Apps List
- Press Windows Key + I to open Settings.
- Go to Apps > Installed apps (or Apps & features in older Windows versions).
- Scroll down or search for “Microsoft Outlook” or “Microsoft 365”.
- Click the three dots next to the entry and select Modify (or just look at the version number listed below the app name).
Note: The version shown here is the Office suite version, not always the exact Outlook build. But it gives you a good starting point.
Using Control Panel
- Open Control Panel from the Start menu.
- Select Programs and Features.
- Find “Microsoft Office” or “Microsoft 365” in the list.
- Look at the Version column. This is the overall Office version number.
This method is less precise but works when Outlook itself is broken. The version number here might be something like “16.0.16130.20218” which corresponds to the same build you would see in the About Outlook window.
Identifying Outlook Version From The Ribbon Or Title Bar
Sometimes you can guess the version just by looking at the interface. Each major Outlook version has distinct visual features.
Visual Clues For Common Versions
- Outlook 2019 / Microsoft 365: Has a simplified ribbon with icons. The title bar shows “Outlook” with no year number.
- Outlook 2016: Similar to 2019 but with a slightly different color scheme. The title bar says “Outlook 2016”.
- Outlook 2013: Uses a flat, clean design with a white background. The title bar says “Outlook 2013”.
- Outlook 2010: Has a more colorful ribbon with gradients. The title bar clearly says “Microsoft Outlook 2010”.
- Outlook 2007: Uses the older Office Fluent interface with a large round Office button.
These visual cues are not 100% reliable because updates can change the look. But they give you a quick idea.
Using Command Line To Find Outlook Version
For advanced users or IT administrators, you can find the Outlook version using the command line. This is useful for scripting or remote troubleshooting.
Using PowerShell
- Press Windows Key + X and select Windows PowerShell (Admin).
- Type the following command and press Enter:
Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*Outlook*"} | Select-Object Name, Version - Look for the line that shows “Microsoft Outlook” and its version number.
This command queries the Windows Management Instrumentation database. It may take a few seconds to run. The version number returned is the exact build number.
Using Command Prompt
- Open Command Prompt as administrator.
- Navigate to the Outlook installation folder. Typically:
cd "C:\Program Files\Microsoft Office\root\Office16" - Type
outlook.exe /?and press Enter. The version info will appear in the first line of output.
Note: The folder path may vary. For 32-bit Office on 64-bit Windows, the path is usually C:\Program Files (x86)\Microsoft Office\root\Office16.
Checking Outlook Version On Mac
If you use Outlook for Mac, the process is slightly different. The version number is found in the application menu.
Steps For Mac Users
- Open Outlook on your Mac.
- Click Outlook in the top menu bar (next to the Apple logo).
- Select About Outlook.
- A window will pop up showing the version number, such as “16.72.23031200”.
The version number format is similar to Windows. The first two digits (16) indicate the major version. The next two (72) are the minor version. The remaining digits are the build number.
For Outlook 2011 for Mac, the version number is found under Outlook > About Outlook as well. The interface is older but the method is the same.
Understanding The Version Number Format
Once you have the version number, you need to know what it means. Microsoft uses a specific format for Outlook versions.
Click-To-Run Vs. MSI Versions
Most modern Outlook installations use Click-to-Run (C2R) technology. The version number looks like: Version 2302 (Build 16130.20218 Click-to-Run). The “2302” means the update was released in February 2023. The build number is the exact code version.
Older MSI-based installations (like volume licensed versions) show a simpler number like 16.0.4266.1001. The first part (16) is the major version for Office 2016 or later.
Major Version Numbers
- 16.0: Outlook 2016, 2019, 2021, or Microsoft 365 (all use the same core version)
- 15.0: Outlook 2013
- 14.0: Outlook 2010
- 12.0: Outlook 2007
- 11.0: Outlook 2003
If you see version 16.0, you need to look at the build number to tell which specific version you have. For example, build 10325.20018 is Outlook 2016, while build 16130.20218 is Microsoft 365.
Why You Need To Know Your Outlook Version
Knowing how to find out what version of Outlook I have is not just a trivia question. It has practical applications in daily work.
Compatibility With Email Servers
Some email servers require specific Outlook versions. For example, Exchange Online might require Outlook 2016 or later for full functionality. Older versions may have limited support.
If you are setting up a new email account and getting errors, the first thing support will ask is your Outlook version. Having this information ready saves time.
Installing Add-Ins And Plugins
Many third-party add-ins specify which Outlook versions they support. A plugin for Outlook 2019 might not work on Outlook 2013. Checking your version before purchasing or downloading prevents frustration.
Some add-ins also require specific build numbers. For example, a security plugin might need build 16130 or higher. Knowing your exact build helps you decide if you need to update.
Troubleshooting Crashes And Errors
When Outlook crashes frequently, support teams need your version number to identify known issues. Microsoft releases patches for specific builds. If you have an older build, updating might fix the problem.
Error messages often include version-specific information. For instance, “Outlook 2016 (Build 4266.1001) stopped working” is a common pattern. Knowing your version helps you search for solutions online.
How To Update Outlook To The Latest Version
Once you know your version, you might want to update it. Keeping Outlook updated ensures you have the latest features and security fixes.
For Microsoft 365 Subscribers
- Open Outlook and go to File > Office Account.
- Under Product Information, click Update Options.
- Select Update Now. Outlook will check for updates and install them.
- Restart Outlook after the update completes.
Updates are usually monthly. You can also set Outlook to update automatically by choosing Enable Updates in the same menu.
For Standalone Versions (2019, 2021)
Standalone versions like Outlook 2019 do not receive feature updates. They only get security patches. To check for updates, go to File > Office Account > Update Options > Update Now.
If you want the latest features, consider switching to a Microsoft 365 subscription. Standalone versions are frozen in time after their release.
Common Mistakes When Checking Outlook Version
Even experienced users make errors when trying to find their Outlook version. Here are some pitfalls to avoid.
Looking At The Wrong Number
Some users confuse the Outlook version with the Windows version. The “About Outlook” window shows the correct number. Do not look at the title bar of the main window, as it might just say “Outlook” without a version.
Also, the version number in Control Panel is for the entire Office suite. It might not match the exact Outlook build if you have multiple Office products installed.
Using An Outdated Method
Older tutorials tell you to go to Help > About. In modern Outlook versions, the Help menu is hidden. Always use the File > Office Account method first.
If you are using Outlook on a Mac, the Help menu method works. But on Windows, it is deprecated.
Frequently Asked Questions
How Can I Tell If I Have Outlook 2016 Or 2019?
Look at the build number. Outlook 2016 has build numbers starting with 16.0.4266 to 16.0.10325. Outlook 2019 has builds from 16.0.10326 to 16.0.15000. Microsoft 365 builds are 16.0.15000 and above. You can also check the title bar; Outlook 2016 says “Outlook 2016” while Outlook 2019 says “Outlook 2019”.
What If My Outlook Version Is Not Showing In File > Office Account?
This usually happens if you have an older version like Outlook 2010 or 2007. Try Help > About Microsoft Outlook instead. If that does not work, check the Control Panel or use the PowerShell method described above.
Does The Outlook Version Matter For Email Compatibility?
Yes, especially for modern email protocols. Outlook 2013 and earlier may have trouble with OAuth 2.0 authentication required by Gmail and Microsoft 365. For best compatibility, use Outlook 2016 or later.
Can I Find The Outlook Version Without Opening The Program?
Yes. Use the Windows Settings app or Control Panel to see the installed Office version. You can also check the file properties of outlook.exe in the installation folder. Right-click the file, select Properties, and look at the Details tab.
Why Does My Outlook Version Change Every Month?
If you have Microsoft 365, Microsoft releases monthly updates with new features and security fixes. The version number changes to reflect these updates. This is normal and ensures you have the latest improvements.
Final Tips For Keeping Track Of Your Outlook Version
Now that you know how to find out what version of Outlook I have, make it a habit to check periodically. Write down the version number when you first install Outlook. Then check again after major updates.
If you work in an IT department, consider using group policy or scripts to automatically log Outlook versions across your organization. This helps with compliance and troubleshooting.
Remember that the version number is not just a number. It is a key piece of information that unlocks better support, compatibility, and performance. Keep it handy for when you need it.
In summary, the quickest way to find your Outlook version is File > Office Account > About Outlook. For older versions, use Help > About. For Mac, use Outlook > About Outlook. And if Outlook is broken, use Windows Settings or PowerShell. With these methods, you will never be stuck wondering what version you have.
