Allowing External Users to Join Your Teams Channels

Across the planet people are using video conferencing and collaboration tools to work together. One of the systems at the forefront of this movement is Microsoft Teams.

By default Teams allows individuals who work in the same organisation (share the same domain) to work together, but with just the change of one setting you can get people using personal and business email addresses working together.

For this to work, you need to be the administrator for your Office 365 Exchange, with access to the Admin panel in Office 365.

Enabling Guest Access

1. Go to the Microsoft Teams admin center, select Org-wide settings, then click on Guest access.

Teams Admin Panel

2. Toggle the Allow guest access in Teams switch to On. Then click Save.

Team Save Changes - Guest Account

The change can take up to 24 hours for changes to take effect, but once it is active you are good to go forever (or until you change the setting back).

Add a guest to your team in Microsoft Teams

Once you’ve enabled guest access and configured your org-wide settings to your liking, it’s time to start adding some guests!

Only team owners can add a guest in Teams, so if you’re an IT admin you might need to make yourself an owner of a team before you start adding guests to it. (You can do this is in the Teams admin center by selecting Teams > Manage teams)

To add a guest to your team in Teams:

1. In the Teams app, select Teams on the left sidebar and go to the team you want to add a guest to.

2. Select More options () then Add member.

3. Enter the guest’s email address, then click on Edit guest information to give them a friendly user name. Then click Add. Your guest will receive a welcome email invitation.

Teams - Adding Guests to a Channel

Guests must have an Office 365 work or school account. If they don’t have a Microsoft account associated with their email, they’ll be prompted to create one for free.
