Microsoft Teams allows administrators to add guests to a team in the Teams Client or from the Administration Center. However, some users have reported the problem “Microsoft Teams cannot add guests”.

If you are also affected by this issue, here are some troubleshooting steps to resolve it.

Enable Guest Access at Teams Org-wide Level

The ability for Microsoft owners or team members to invite a guest or external user to teams has been available for almost a year. Although Microsoft provides documentation on how to configure this system, there are still some issues and several places to look, depending on your configuration. To fully install and configure it, you need to follow all the steps below.

To enable guest access, go to the Microsoft Teams Administration Center.

  • In the Team Administration Center, select Organization-wide Settings > Guest Access.
  • Select the Allow guest access in Microsoft Teams check box to Enabled.
  • On the same page, enable or disable call, meeting, and message settings for guests.
  • Click Save.

Granting Guest Access with the PowerShell command

If the problem persists, you can add guest users to Microsoft Teams using the PowerShell command.

Here’s how to do this:

  • Open PowerShell as an administrator.
  • Log in to Office 365 with PowerShell.
  • Once you are logged in to the Office 365 administrator, type the following command :
  • Set-MsolCompanySettings -UsersPermissionToRe OtherUsersEnabled $True
  • Now try adding the guest user and see if the problem is solved.

Check for Latency Issues on Microsoft Teams

  • Sometimes Microsoft Teams may experience temporary latency for guest changes.
  • Wait a few minutes and then try to add the guest user again.

Updating Microsoft Teams

The desktop application is updated automatically (so you don’t have to). If you wish, you can always check for available updates by clicking on your profile picture at the top of the application and then choosing Check for Updates.

The web application is always up to date. That’s fine.
