Troubleshooting Microsoft Teams Issues When Someone Appears Unavailable

Various users of Microsoft Teams have reported an issue where they cannot call another member of their organization or an external contact they know is available on Teams. When attempting to initiate a call, they are informed that the person they're trying to reach isn't available on Teams, even though the individual is active and using Teams. The message 'The person you're trying to reach isn't available in Teams' might result from multiple factors. It could be due to the Coexistence Mode setting, which might not be set to 'Teams only,' causing confusion between Teams and Skype for Business. Another possible cause is logging-in issues; sometimes, logging out and logging back in can fix a myriad of problems. Outdated MS Teams versions could also be responsible for the issue. Lastly, problems with the Teams application might need resetting or repairing.

Handy Solutions to the Problem

If you experience the 'The person you're trying to reach isn't available in Teams' issue, several possible solutions might help. Here are some of the most notable ones:

Set Coexistence Mode to Teams only

Make sure your Coexistence Mode is set to 'Teams only.' This action can ensure no confusion between Teams and Skype for Business when making calls. If your coexistence mode includes Skype for Business, you might need to launch it, ensuring that the person you're trying to call is available across both platforms. Here's how you can set the coexistence mode to "Teams only":

1. Sign in to Microsoft Teams Admin Center: Log in to your Microsoft Teams Admin Center using your admin credentials.
2. Navigate to Coexistence Settings: In the Admin Center, navigate to "Org-wide settings" and select "Teams upgrade."
3. Choose Coexistence Mode: In the "Teams upgrade" section, you'll see the "Coexistence mode" options. Select "Teams only" from the dropdown menu.
4. Apply Settings: After selecting "Teams only," save or apply the changes. This will apply the "Teams only" coexistence mode to your organization.
5. Monitor and Communicate: As you transition to the "Teams only" mode, communicate the changes to your users and guide them on using Teams for their communication and collaboration needs. You can also provide training or resources to help users make the most of Teams.
6. Monitor Adoption and Feedback: Keep an eye on how your users adopt the new mode. Monitor their feedback and address any questions or concerns that may arise during the transition.

It's important to note that setting the coexistence mode to "Teams only" might require a careful transition plan, especially if your organization has been using other communication tools alongside Teams. This change may impact users using other tools, so effective communication and training are essential. Also, remember that the exact steps and options might vary based on updates to the Microsoft Teams Admin Center and the specific settings in your organization's account. Refer to the official Microsoft Teams documentation or contact your IT support for accurate and up-to-date instructions.

Log out and Log back in

Logging out and logging back into Microsoft Teams can help resolve various issues or refresh your connection to the application. Try this easy fix to refresh your Teams' status. Here are the steps to log out and log back in:

1. Open Teams Application: Launch the Microsoft Teams application on your computer or device.
2. Click on Your Profile Picture: In the top right corner of the application window, click on your profile picture or initials. This will open a dropdown menu.
3. Click on "Sign Out": Click on the "Sign Out" option from the dropdown menu. This will log you out of your Teams account.
4. Log Back In: After signing out, you'll be taken to the Teams login page. Enter your email address and password associated with your Microsoft account.
5. Click "Sign In": Once you've entered your credentials, click the "Sign In" button. Teams will log you back in.
6. Two-Factor Authentication (if enabled): If you have two-factor authentication enabled for your Microsoft account, you might need to complete the additional verification step.

If you continue to experience problems after logging back in, consider checking for updates to Teams, your operating system, or consulting your IT support for further assistance.

Use the MS Teams Website

If the app is causing issues, try accessing Teams via the website. The Microsoft Teams website provides a convenient way to access Teams' core features without requiring the installation of a dedicated app. A number of reports suggest that the Teams website operates seamlessly and doesn't seem to exhibit the same issues faced on the app. This implies that using the site version, at least in the meantime, could be a good workaround while waiting for a more stable update or a lasting fix. With the website, you can enjoy the same functionalities and continue communicating with team members or external contacts without any hitch. It's particularly useful for users who need to quickly access Teams from devices where the app isn't installed or when using shared devices. This action can help you determine whether the problem lies with the application or elsewhere.
