Summary

This guide helps you troubleshoot and resolve: How to Fix Microsoft Teams Chat Not Syncing Between Desktop and Mobile App for Brisbane Small Businesses. Follow the steps below to fix the issue.

Common Causes

Microsoft Teams chat not syncing between your desktop and mobile apps can disrupt communication for your Brisbane small business. When messages appear on one device but not the other, it is usually caused by connectivity issues, outdated app versions, or account session errors. This guide walks you through the steps to restore sync across your devices.

Quick Fix Steps

1. Restart both the Microsoft Teams desktop app and mobile app.
2. Check that both devices have a stable internet connection.
3. Sign out of Teams on both devices, then sign back in with your 220 Internet Services Microsoft 365 account.
4. Check for and install any available updates for Teams on desktop and mobile.

Detailed Instructions

1. Restart Microsoft Teams

1. Close Microsoft Teams completely. On Windows, right-click the Teams icon in the system tray and select Quit. On Mac, right-click the Teams icon in the Dock and select Quit.
2. On mobile, swipe the Teams app away from your recent apps list to close it.
3. Reopen Teams on both devices and check if recent chats appear.

2. Sign Out and Sign Back In

1. In the Teams desktop app, click your profile picture in the top-right corner.
2. Select Sign out.
3. On mobile, tap your profile icon, go to Settings, and select Sign out.
4. Sign back in using your full business email address and password.
5. Wait a few minutes for chats to synchronise.

3. Check for App Updates

1. Desktop: Click your profile picture, select Check for updates, and install any available updates.
2. iPhone/iPad: Open the App Store, tap your profile icon, scroll to Available Updates, and update Teams if listed.
3. Android: Open the Google Play Store, search for Microsoft Teams, and tap Update if available.

4. Clear Teams Cache (Desktop Only)

1. Quit Microsoft Teams completely.
2. Press Windows Key + R to open the Run dialog.
3. Type %appdata%\Microsoft\Teams and press Enter.
4. Delete the contents of the Cache, Blob_storage, databases, GPUCache, IndexedDB, Local Storage, and tmp folders. Do not delete the entire folder.
5. Restart Microsoft Teams and sign in again.

Clearing the cache removes local temporary files but does not delete your chat history, which is stored in the cloud.

5. Verify Mobile Notification and Background Settings

1. iOS: Go to Settings > Teams and ensure Background App Refresh is enabled.
2. Android: Go to Settings > Apps > Teams > Mobile data & Wi-Fi and ensure background data is allowed.

Troubleshooting

Messages Missing on Mobile Only

• Ensure you are signed in with the same Microsoft 365 account used on desktop.
• Check that you have not accidentally muted the chat or channel.
• Verify your mobile device is not in Do Not Disturb or Focus mode.

Messages Missing on Desktop Only

• Confirm you are not in Offline mode. Click your profile picture and ensure Available or another online status is selected.
• Clear the Teams cache using the steps above.
• Restart your computer and reopen Teams.

Sync Delays Between Devices

• Switch your mobile device between Wi-Fi and mobile data to rule out network issues.
• Check for bandwidth-heavy downloads or uploads on your office network that may be slowing sync.
• If the issue started recently, confirm no changes were made to your Microsoft 365 licence or account permissions.
• Check the Microsoft 365 service health dashboard for any ongoing Teams service issues.

Avoid uninstalling and reinstalling Teams unless advised by support, as this may remove local call history and meeting details not yet synced to the cloud.

If chat messages still fail to sync after following these steps, Open a Ticket with 220 Internet Services support.
