Logi Options+ is a desktop application for Windows and does not integrate directly into the Microsoft Outlook interface. To configure MX Keys or MX Master 3 buttons, you must open the standalone Logi Options+ app from your Start menu or system tray, as Outlook cannot access these hardware settings natively.
Distinguishing Desktop Software from Outlook
A common point of confusion arises because both Microsoft and Logitech use modern, lightweight applications. The "New Outlook" for Windows is a UWP (Universal Windows Platform) app designed for email management, while Logi Options+ is a traditional Win32 desktop utility that handles HID (Human Interface Device) input mapping. These two ecosystems do not share a plugin architecture. You cannot find Logitech device settings inside the Outlook ribbon, file menu, or settings pane. Attempting to look for integration within Outlook will lead to dead ends because the software simply does not exist in that context.
If you are experiencing issues with button customization, the problem lies entirely within the Logitech ecosystem, not the Microsoft one. The following steps guide you through accessing the correct tool on Windows 10.
Locating Logi Options+ on Windows 10
To begin configuring your MX Master 3 or MX Keys, you need to launch the application. If you have previously installed it, it may be pinned to your taskbar or start menu. If it is missing, follow these diagnostic steps to locate or reinstall it.
- Check the System Tray: Look at the bottom right of your screen near the clock. Click the up arrow to show hidden icons. If you see a blue Logitech icon, click it to open the main dashboard. This is the fastest way to access settings if the app is already running in the background.
- Search via Start Menu: Press the Windows key and type "Logi Options+". If the application appears in the search results, click to launch it. Note that if you only see "Logitech Options" (without the plus), you may be using the legacy version, which has different capabilities than Options+.
- Install via Microsoft Store: If the app does not appear in search, open the Microsoft Store on your PC. Search for "Logi Options+" and install the official application published by Logitech. This ensures you have the latest driver support for Windows 10.
Once the application is open, you should see your connected devices listed on the left sidebar. Select your MX Master 3 or MX Keys to view the current configuration profile.
Configuring Button Assignments
The core functionality of Logi Options+ allows you to remap physical buttons to specific actions. For the MX Master 3, this includes the thumb wheel, gesture button, and side buttons. For MX Keys, it involves function keys and shortcut rows.
- Select the Device: In the left panel of the Logi Options+ window, click on the icon representing your mouse or keyboard. Ensure the device shows as "Connected." If it shows "Disconnected," check your USB receiver or Bluetooth pairing status in Windows Settings.
- Edit Button Actions: Click on the specific button you wish to change. A menu will appear allowing you to assign actions such as "Copy," "Paste," "Switch App," or "Launch Application." You can also assign custom shortcuts that work across all Windows applications, including Outlook.
- Create Profiles: One of the most powerful features is creating profiles based on the active application. You can create a profile named "Outlook" that assigns specific macros to your mouse buttons only when Outlook is the focused window. This allows for context-sensitive workflows without manual switching.
After making changes, they apply immediately. You do not need to restart either Outlook or the Logi Options+ application. Test your new configurations by clicking the buttons while Outlook is open.
Troubleshooting Connection Issues
If Logi Options+ fails to detect your MX Master 3 or MX Keys, the issue is usually related to drivers or permissions rather than Outlook itself. Since Outlook does not interact with these devices, troubleshooting should focus solely on the Windows environment.
First, verify that the Logitech Connection Utility service is running. Open Task Manager (Ctrl+Shift+Esc) and look for processes named "LogiOptionsService" or "Logitech Unifying Service." If these are missing, reinstall Logi Options+ to restore the necessary background services. Second, ensure that your Windows 10 installation is updated. Older builds of Windows 10 sometimes have compatibility issues with newer HID drivers used by the MX series.
If you recently switched to New Outlook and noticed changes in your workflow, remember that New Outlook runs in a sandboxed environment. It does not have elevated privileges to modify system-wide input devices. Therefore, any button remapping must still be handled by the desktop Logi Options+ app, which runs with standard user privileges but has direct access to the hardware layer.
For users who frequently switch between classic Outlook and New Outlook, note that the application name visible in Logi Options+ profiles may differ slightly. Classic Outlook appears as "outlook.exe," while New Outlook often identifies itself differently in the process list. You may need to create separate profiles for each version if you want distinct button behaviors.
Frequently Asked Questions
Can I sync my Logi Options+ settings to the cloud?
Logi Options+ stores configuration files locally on your Windows PC by default. While some Logitech devices support cloud syncing for firmware updates, button mappings are generally saved to the local application data folder. To back up your settings, manually copy the configuration folders located in your AppData directory.
Why does my MX Master 3 stop working after updating Windows?
Windows updates often replace generic HID drivers with specific manufacturer drivers. When this happens, the connection between the mouse and Logi Options+ may break. Reinstalling the latest version of Logi Options+ from the Microsoft Store or Logitech website usually resolves driver conflicts caused by OS updates.
Is Logi Options+ compatible with Microsoft Teams?
Yes, Logi Options+ works with any Windows application, including Microsoft Teams. You can create a specific profile for Teams to assign mute, camera toggle, or meeting join actions to your mouse buttons. This functionality is independent of your email client settings.
How do I remove offline emails from Outlook on a sign-out device?
This is a separate issue from hardware configuration. If you need to manage cached data in Outlook, refer to our guide on Removing Offline Emails from Outlook on a Sign-Out Device. Hardware button settings do not influence how Outlook manages local cache files.
What should I do if the Repair Button is missing in Outlook 2019?
If you are encountering UI issues in older versions of Outlook, such as missing repair tools, this is unrelated to Logitech peripherals. For those problems, check our article on SCANPST.exe Missing Repair Button in Outlook 2019 on Windows 10: A Solution.
