Uninstall Teams Free Classic and Install the Current Microsoft Teams App

Remove the outdated or incorrect Teams application and install the official desktop app linked to your Microsoft 365 subscription.

Frequently Asked Questions

Why does Teams Free Classic keep opening instead of my Microsoft 365 version?

This usually happens if the Teams Free Classic app is still installed on your device, or if your system automatically signs you in using a personal Microsoft account instead of your Microsoft 365 work or school account.

Can I use a personal Microsoft 365 subscription to get full Teams features?

Personal Microsoft 365 subscriptions provide a different Teams experience than work or school accounts. For full integration with enterprise Outlook and advanced features, a Microsoft 365 work or school account is required.

How do I fix Microsoft Teams not connecting to Outlook?

Ensure that both Microsoft Teams and Outlook are signed into the exact same Microsoft 365 work or school account. Using Teams Free Classic or mismatched accounts will prevent your calendar and emails from synchronizing.
