Microsoft Teams External Users: How to Add Guests?

Microsoft Teams are meant to be used within an organization. Generally, users are set up via an active directory and usually from the same network or organization. Because it’s free, it can also be used outside of an organization, as users can bring anyone on board by simply sending them an invitation.

So how exactly does it work to add Microsoft Teams external users? Let’s divide it into two categories:

  • If you use Microsoft Teams with you personal account, you can invite anyone.
  • If you have a corporate account however, it is linked to a business license, and the invitation of outside users is usually limited.

But what if you encounter a problem and cannot add guests or external users?

On a business license, Microsoft Teams must restrict users from adding guests unless an organization explicitly activates it.

This is done to keep the data shared about Teams private, and also to restrict who is able to use a business license or the company’s features.
