While Microsoft Teams is jam-packed with useful features, the software puts a huge question mark over the overall reliability.

It can be baffling when Microsoft Teams doesn’t work whenever you launch it on your Mac. Here’s how to get Microsoft Teams up and running on Mac.
1. Force Quit Teams
Well, this is the first thing you should try, if you haven’t already. If Teams is misbehaving on Mac, you can force quit the app and try relaunching it. Here’s how.
Step 1: Press the command + space keys and search for Activity Monitor.
Step 2: Hit Return and open the app.

Step 1: Open Finder on Mac and select Go in the menu bar.
Step 2: Click on Go to Folder.
Step 3: Paste the following path into it:
Step 4: Select the Teams folder and move it to trash.
Step 5: Press Command + Space to open Spotlight Search, type Keychain Access and hit Return to launch the app.
Step 6: Search for Microsoft at the top and select Microsoft Teams Identity Cache entry.
Step 7: Right-click on the Microsoft Teams Identities Cache and delete the entry.
Click on the Apple icon in the top-left corner on the menu bar and select Restart. Start using Teams again.
3. Reinstall Teams
Another option is to reinstall Microsoft Teams on Mac. Here’s how you can uninstall Teams and download it again.
Step 1: Open Finder on Mac and go to the Applications menu.
Step 2: Find Microsoft Teams in the list and select it.
Step 3: Right-click on the app icon and select Move to Trash.
Step 4: Download Microsoft Teams directly from the company’s website.

4. Open Microsoft Teams Using an Invite Link
When you receive an invite to join an organization, you get an email for the same. Return to the email inbox and find the invite link. Click on the Teams invite link and it will open the organization in the Teams app again.
5. Disconnect VPN
Most paid VPN services offer fast servers around the world. While some freemium ones don’t have hundreds of servers to deliver good internet speeds. When you are working with such VPN services, you might face issues with installed apps on Mac including Microsoft Teams. Or probably you forgot about using VPN.
Also, when Teams detect an unusual IP address from your Mac (due to VPN), it might block the app access to verify user identity. Open the VPN app on your Mac and disable it.
6. Quit Other Apps
This trick is most applicable to Macs with less than 8GB of RAM. If you are using memory-intensive apps like Outlook, Teams, on Mac, you might end up with little to no RAM on Mac.
macOS does come with memory swapping to use the SSD storage as RAM but even that can’t be sufficient at times. Simply hitting the ‘x’ mark in the app menu bar doesn’t close it completely on the Mac. To free up RAM for Teams on Mac, you need to use the Activity Monitor.
Step 1: Open Activity Monitor on Mac (refer to the first trick at the top).
Step 2: Find apps that are consuming high memory on Mac. Select an app and click on x mark at the top.
Repeat the same for all unnecessary apps running on Mac.
7. Open Teams at Startup
If Microsoft Teams is a vital part of your work, you can open the app right at the Mac startup.
Step 1: Click on the Apple icon in the top-left corner and select System Preferences from the menu.
Step 2: Select Users & Groups.
Step 3: Click on Login Items tab.
Step 4: Click on the + icon at the bottom and select Teams from the Applications menu.
From now on, Teams will launch at Mac startup and stop throwing errors.
8. Check Microsoft Teams Status
Microsoft services including Teams doesn’t win any awards in terms of reliability. If the app servers are facing outage, you won’t be able to open the app on Mac.
Head to Downdetector and search for Teams. If others are facing the same, you will see high outage graphs. Wait for Microsoft to resolve the issues from the server-end.
9. Use Microsoft Teams Web
Microsoft Teams is available on the web as well. If you are still facing issues with the Teams Mac app, you can temporarily switch to Teams web and take time-sensitive calls and reply to messages on priority.
