These steps are designed to help you get Yammer running smoothly again. Let’s begin with some quick checks before moving into detailed troubleshooting.

Read through each step carefully and perform them one at a time to identify what works best for your situation.

Quick Note: Important Checks Before You Start

Check Your Internet Connection: Yammer requires a stable internet connection. Make sure you are connected to Wi-Fi or Ethernet.
Verify Your Login Credentials: Ensure you are using the correct username and password to log in.
Update Windows 11: Sometimes, system updates fix compatibility issues. Go to Settings > Windows Update and install any pending updates.
Confirm Yammer Server Status: Visit the Microsoft Office Service Status page to check if Yammer services are down.

Step 1: Restart the Yammer App

Sometimes, simply closing and reopening the app can fix temporary glitches.

Click the X button on the Yammer app window to close it completely.
Open the Task Manager by pressing Ctrl + Shift + Esc.
Look for any running processes named “Yammer.” If found, right-click and select End task.
Reopen Yammer from the Start menu or desktop shortcut.

This ensures no hidden app processes interfere with your session.

Step 2: Check for Yammer App Updates

An outdated app can cause issues. Keeping the app updated helps fix bugs and improves performance.

Open the Microsoft Store from the Start menu.
Click on the Library icon at the bottom left.
Find Yammer in the list and click Update if available.
After updating, restart the app and check if it works properly.

Step 3: Clear Yammer Cache

Cached data can sometimes become corrupted, causing the app to malfunction. Clearing the cache resets temporary files.

Press Windows + R to open the Run dialog box.
Type %localappdata%Packages and press Enter.
Find the folder related to Yammer. It usually starts with Microsoft.Yammer_.
Open the folder and delete the LocalCache subfolder.
Restart the Yammer app.

This forces the app to create new cache files and can resolve loading problems.

Step 4: Reinstall the Yammer App

If clearing cache doesn’t help, reinstalling the app can fix deeper issues by replacing corrupt files.

Go to Settings > Apps > Installed apps.
Scroll down to find Yammer and click the three dots (⋮) next to it.
Select Uninstall and confirm.
After uninstallation, open the Microsoft Store and search for “Yammer.”
Click Install to download a fresh copy.
Open the app and log in again.

Step 5: Reset Network Settings

Network issues can block Yammer’s access. Resetting network settings can fix connectivity problems.

Open Settings and go to Network & Internet.
Scroll down and click on Advanced network settings.
Click on Network reset.
Click the Reset now button and confirm.
Your PC will restart. After reboot, reconnect to your network and try Yammer again.

This clears any network configuration errors that may block the app.

Step 6: Run the Windows Store Apps Troubleshooter

Windows 11 comes with a built-in troubleshooter for apps installed via Microsoft Store. This tool can detect and fix common app issues.

Go to Settings > System > Troubleshoot > Other troubleshooters.
Find Windows Store Apps and click Run.
Follow the on-screen instructions to complete the troubleshooting process.
Restart your computer if prompted and test the Yammer app again.
