If you have a personal Office 365 subscription, you won't be able to access Microsoft Teams. To access the app, you need one of the following Office 365 license plans:
- Business Essentials
- Business Premium
- Enterprise E1, E3, or E5
- Enterprise E4 (for anyone who purchased this plan prior to its retirement)
You can still use the free version of Teams. Details as well as a comparison table can be found in the article linked below:
