How to Fix Microsoft Teams Not Loading or Opening Issue

Microsoft Teams completes the whole circle for those invested heavily in Microsoft’s software-services ecosystem. Add to the fact that Microsoft has decided to discontinue Skype for Business, and you should certainly look for a worthy replacement. That’s not the only problem. Other users have complained that Teams is not loading or opening for them at all.

While there is nothing you can do about the first problem, there are steps you can take to resolve the loading issue. The solutions are easy enough to follow.

Let’s begin.

1. Downtime

As discussed in the opening para, servers can be down with so many people across the world, relying on Teams to communicate and collaborate on tasks. But how do you know?

Instead of taking it to Twitter, you can visit Downdetector to check the software’s working status. It’s a cool site that tracks popular apps and services. There is a live outage map with details on the most commonly reported errors. You can also check past events.

2. Known Error Codes

Here are some common error codes that will help you understand the problem in more detail. Have you seen any of these error codes on your screen?

• 0xCAA20003 – Authorization problem
• 0xCAA82EE2 – Request timed out
• 0xCAA82EE7 – Server named not resolved
• 0xCAA20004 – Request not approved
• 0xCAA90018 – Wrong login credentials
• none – Re-enter pin with a smart card

These errors are easy enough to solve, and you won’t be needing my help with here.

3. Try Another Platform and Connection

Troubleshooting can take time, and there is work to be done. Here’s a quick fix. Microsoft Teams app is available on the web, desktop, and mobile. Have you tried a different platform like Windows, Android, or a different browser like Firefox?

You should try and sign in to Teams using a different internet connection. If it works, then you need to check your antivirus and firewall settings. Microsoft has created a handy guide of URLs and IP address ranges for Microsoft Teams and its other apps. Check them out.

4. Reboot and Retry

Close the app and reboot your computer once. Save everything so that you don’t lose any important data. It shouldn’t take more than a few moments but is known to help with several common software related bugs. Launch the app again and check if Teams is still not loading or opening as it should.

5. Sign Out

Quite a few users have tagged this to be working in one Microsoft thread. Worth a try. If Teams is crashing before you can do anything on Windows 10, look for the Teams icon in the System Tray area. Is it appearing and disappearing within a second?

That will take some time and practice but what you need to do is right-click on that icon and click sign out. That applies to desktop users. If you are quick enough, you should sign out/Quit, and Teams will load correctly the next time you launch.

For those who are looking for specifics, the error has to do with event log DCOM permission (10016) entry.

6. Troubleshoot Teams

Press Windows key+I shortcut to open Settings. Search for Find and fix problems with Windows Store Apps in the search box.

From the window that pops up, click on the box before ‘ Apply repairs automatically’ option and select Next.

Follow on-screen instructions after that to fix Microsoft Teams not working issue.

7. Uninstall and Delete Cache and Other Files

The steps will vary based on the platform you are facing the Teams not loading issue on. We want to clear the cache and other temp files. Let’s start with Windows 10. Exit Teams completely so that it is not running in the background or even in the System Tray. You can right-click and exit from there or press Ctrl+Shift+Esc shortcut to open Task Manager and kill Teams task from there.

Uninstall the app from the Control Panel or use a third-party app. Press Windows key+E shortcut to open File Explorer and past this location in the address bar:

%appdata%\Microsoft\teams

In the window that pops up, you will find that you need to delete before restarting Teams again.

• Delete all files in Application Cache > Cache
• Delete all files in blob_storage, Cache, databases, GPUCache, IndexedDB, Local Storage, and tmp folders.

Here are the steps for Android users. Open Settings and go to the app list or manage apps section and search for Teams.

Tap on Clear data button at the bottom of the screen and select both options one at a time.

Reinstall Microsoft Teams. We did that so that old data and cache doesn’t cause trouble while we perform a clean reinstall.

Try clearing browser cache if you are facing this issue in the Chrome browser.

Reinstalling Teams from scratch will also bring you up to speed with the latest version which might carry some performance improvements and major fixes.

8. Reinstall in Default Location

You can skip this solution if Teams was loading fine until it started acting up randomly. If you have installed Teams for the first time and it is not opening or showing a white screen, continue.

Microsoft says that Teams should be installed in the default location which is:

C:\users\USERNAME\appData

Most users install the Windows OS in the C: drive, which is where the above folder should be located. You will have to reinstall Teams in the correct, default, location if that is not the case. Once done, check again if Microsoft Teams is opening/loading or not.

Team Work Rocks

Microsoft Teams is shaping into one of the best apps for communication and collaboration. It is an improvement over Skype for Business and brings plenty of features from even Slack. It makes a lot of sense if you are already using Office suite in some capacity. I hope this guide was able to solve the Teams not loading or opening error on your end.
