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.
Jun 05, 2020 As you are using Mac version 10.10.5, the office suites which include Teams may be not compatible with your OS version. This is why Teams is not installed. To install Microsoft Teams, you could go to this link to download the standalone version of Teams. If you have any concerns, please feel free and come back to share with us.

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.
Visit Downdetector2. 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.

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.

Click here to see our Work From Home articles page7. 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:
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:
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.

-->Microsoft Teams has clients available for desktop (Windows, Mac, and Linux), web, and mobile (Android and iOS). These clients all require an active internet connection and do not support an offline mode.
Note
For details about each clients' capabilities on different platforms, see Teams features by platform.
Note
Effective November 29, 2018, you'll no longer be able to use the Microsoft Teams for Windows 10 S (Preview) app, available from the Microsoft Store. Instead, you can now download and install the Teams desktop client on devices running Windows 10 S mode. To download the desktop client, go to https://teams.microsoft.com/downloads. MSI builds of the Teams desktop client are not yet available for devices running Windows 10 S mode.
For more information about Windows 10 S mode, see Introducing Windows 10 in S mode.
Desktop client
Tip
Watch the following session to learn about the benefits of the Windows Desktop Client, how to plan for it, and how to deploy it: Teams Windows Desktop Client
The Microsoft Teams desktop client is a standalone application and is also available in Microsoft 365 Apps for enterprise. Teams is available for 32-bit and 64-bit versions of Windows (8.1 or later), ARM64 for Windows 10 on ARM, and Windows Server (2012 R2 or later), as well as for macOS and Linux (in
.deb
and .rpm
formats). On Windows, Teams requires .NET Framework 4.5 or later; the Teams installer will offer to install it for you if you don't have it. On Linux, package managers such as apt
and yum
will try to install any requirements for you. However, if they don't then you will need to install any reported requirements before installing Teams on Linux.The desktop clients provide real-time communications support (audio, video, and content sharing) for team meetings, group calling, and private one-on-one calls.
Desktop clients can be downloaded and installed by end users directly from https://teams.microsoft.com/downloads if they have the appropriate local permissions (admin rights are not required to install the Teams client on a PC but are required on a Mac).
Note
For more details about installing Teams on a Chromebook, please see How to install and run Microsoft Office on a Chromebook.
IT admins can choose their preferred method to distribute the installation files to computers in their organization. Some examples include Microsoft Endpoint Configuration Manager (Windows) or Jamf Pro (macOS). To get the MSI package for Windows distribution, see Install Microsoft Teams using MSI.
Note
Distribution of the client via these mechanisms is only for the initial installation of Microsoft Team clients and not for future updates.
Windows
The Microsoft Teams installation for Windows provides downloadable installers in 32-bit and 64-bit architecture.
Note
The architecture (32-bit vs. 64-bit) of Microsoft Teams is agnostic to the architecture of Windows and Office that is installed.
The Windows client is deployed to the AppData folder located in the user’s profile. Deploying to the user’s local profile allows the client to be installed without requiring elevated rights. The Windows client leverages the following locations:
- %LocalAppData%MicrosoftTeams
- %LocalAppData%MicrosoftTeamsMeetingAddin
- %AppData%MicrosoftTeams
- %LocalAppData%SquirrelTemp
When users initiate a call using the Microsoft Teams client for the first time, they might notice a warning with the Windows firewall settings that asks for users to allow communication. Users might be instructed to ignore this message because the call will work, even when the warning is dismissed.
Note
Windows Firewall configuration will be altered even when the prompt is dismissed by selecting “Cancel”. Two inbound rules for teams.exe will be created with Allow action for both TCP and UDP protocols.
If you want to prevent Teams from prompting users to create firewall rules when the users make their first call from Teams, use the Sample PowerShell script - inbound firewall rule below.
Mac
Mac users can install Teams by using a PKG installation file for macOS computers. Administrative access is required to install the Mac client. The macOS client is installed to the /Applications folder.
Install Teams by using the PKG file
- From the Teams download page, under Mac, click Download.
- Double click the PKG file.
- Follow the installation wizard to complete the installation.
- Teams will be installed to /Applications folder. It is a machine-wide installation.
Note
During the installation, the PKG will prompt for admin credentials. The user needs to enter the admin credentials, regardless of whether or not the user is an admin.
If a user currently has a DMG installation of Teams and wants to replace it with the PKG installation, the user should:
Install Microsoft Teams For Mac
- Exit the Teams app.
- Uninstall the Teams app.
- Install the PKG file.
IT admins can use managed deployment of Teams to distribute the installation files to all Macs in their organization, such as Jamf Pro.

Note
If you experience issues installing the PKG, let us know. In the Feedback section at the end of this article, click Product feedback.
Linux
Users will be able to install native Linux packages in
.deb
and .rpm
formats.Installing the DEB or RPM package will automatically install the package repository.- DEB
https://packages.microsoft.com/repos/ms-teams stable main
- RPM
https://packages.microsoft.com/yumrepos/ms-teams
The signing key to enable auto-updating using the system's package manager is installed automatically. However, it can also be found at: (https://packages.microsoft.com/keys/microsoft.asc). Microsoft Teams ships monthly and if the repository was installed correctly, then your system package manager should handle auto-updating in the same way as other packages on the system.

Web client
The web client (https://teams.microsoft.com) is a full, functional client that can be used from a variety of browsers. The web client supports Calling and Meetings by using webRTC, so there is no plug-in or download required to run Teams in a web browser. The browser must be configured to allow third-party cookies.
Teams fully supports the following Internet browsers, with noted exceptions for calling and meetings. This table applies to operating systems running on desktop computers.
Browser | Calling - audio, video, and sharing | Meetings - audio, video, and sharing123 |
---|---|---|
Internet Explorer 11 | Not supported | Meetings are supported only if the meeting includes PSTN coordinates. To attend a meeting on IE11 without PSTN coordinates, users must download the Teams desktop client. Video: Not supported Sharing: Incoming sharing only (no outgoing) Microsoft 365 apps and services will not support Internet Explorer 11 starting August 17, 2021 (Microsoft Teams will not support Internet Explorer 11 earlier, starting November 30, 2020). Learn more. Please note that Internet Explorer 11 will remain a supported browser. Internet Explorer 11 is a component of the Windows operating system and follows the Lifecycle Policy for the product on which it is installed. |

While in preview, there are known issues with Safari's Intelligent Tracking Prevention. |
1 To give and take control of shared content during sharing, both parties must be using the Teams desktop client. Control isn't supported when either party is running Teams in a browser. This is due to a technical limitation that we're planning to fix.
2 Blur my background isn't available when you run Teams in a browser. This feature is only available in the Teams desktop client.
3 Teams meetings on browsers are limited to a single incoming video feed of active speaker.
4 Edge RS2 or later doesn't support sending real-time audio and video traffic through HTTP proxies.
Note
As long as an operating system can run the supported browser, Teams is supported on desktop computers. For example, running Firefox on the Linux operating system is an option for using Teams.
For mobile operating systems, we recommend that you run the Teams app, available from the Android and iOS stores. Running Teams in a mobile operating system is supported, but many features are unavailable.
The web client performs browser version detection upon connecting to https://teams.microsoft.com. If an unsupported browser version is detected, it will block access to the web interface and recommend that the user download the desktop client or mobile app.
Mobile clients
![Microsoft teams for mac free download Microsoft teams for mac free download](/uploads/1/2/6/4/126471777/100953249.jpg)
The Microsoft Teams mobile apps are available for Android and iOS, and are geared for on-the-go users participating in chat-based conversations and allow peer-to-peer audio calls. For mobile apps, go to the relevant mobile stores Google Play and the Apple App Store. The Windows Phone App was retired July 20, 2018 and may no longer work.
In China, here's how to get Teams for Android.
Supported mobile platforms for Microsoft Teams mobile apps are the following:
- Android: Support is limited to the last four major versions of Android. When a new major version of Android is released, the new version and the previous three versions are officially supported.
- iOS: Support is limited to the two most recent major versions of iOS. When a new major version of iOS is released, the new version of iOS and the previous version are officially supported.
Note
The mobile version must be available to the public in order for Teams to work as expected.
Mobile apps are distributed and updated through the respective mobile platform’s app store only. Distribution of the mobile apps via MDM or side-loading is not supported by Microsoft. Once the mobile app has been installed on a supported mobile platform, the Teams Mobile App itself will be supported provided the version is within three months of the current release.
Decision Point | Are there any restrictions preventing users from installing the appropriate Microsoft Teams client on their devices? |
Next Steps | If your organization restricts software installation, make sure that process is compatible with Microsoft Teams. Note: Admin rights are not required for PC client installation but are required for installation on a Mac. |
Client update management
Clients are currently updated automatically by the Microsoft Teams service with no IT administrator intervention required. If an update is available, the client will automatically download the update and when the app has idled for a period of time, the update process will begin.
Client-side configurations
Microsoft Teams Personal Desktop
Currently, there are no supported options available to configure the client either through the tenant admin, PowerShell, Group Policy Objects or the registry.
Notification settings
There are currently no options available for IT administrators to configure client-side notification settings. All notification options are set by the user. The figure below outlines the default client settings.

Sample PowerShell script - inbound firewall rule
Microsoft Teams For Mac Ios
This sample script, which needs to run on client computers in the context of an elevated administrator account, will create a new inbound firewall rule for each user folder found in c:users. When Teams finds this rule, it will prevent the Teams application from prompting users to create firewall rules when the users make their first call from Teams.
