Collaborate ~ External vs. Guest Access

What is the difference between External User Access and Guest User Access?

Create a team

The next step is to create the team that you plan to use for collaborating with guests.

To create a team

  1. In Teams, on the Teams tab, click Join or create a team at the bottom of the left pane.
  2. Click Create a team.
  3. Click Build a team from scratch.
  4. Choose Private or Public.
  5. Type a name and description for the team, and then click Create.
  6. Click Skip.

We'll invite users later. Next, it's important to check the site-level sharing settings for the SharePoint site that is associated with the team.

SharePoint site-level sharing settings

Check the site-level sharing settings to make sure that they allow the type of access that you want for this team. For example, if you set the organization-level settings to Anyone, but you want all guests to authenticate for this team, then make sure the site-level sharing settings are set to New and existing guests.
