In this blog post, I will show you how to enable guest access to Microsoft Teams and allow external users to collaborate.
Guest Access
To start the process, I will log in to the Microsoft Teams admin centre and click on Guest access.
I will change the settings to on.

After switching the settings, I have the option to disable some of the features as shown below.

Azure AD settings
Next, I will log in to Azure AD from the Azure portal.
I will click on Azure Active Directory -> Users -> User settings and click on:
Manage external collaboration settings, as shown below.

From the collaboration settings I can customize the security settings and a few other settings.

It will take 24 hours for the settings to wor.
After 24 you will be able to add external users.
