Microsoft is turning on Guest access in Microsoft Teams by default

Any organisations that have not explicitly disabled guest access in Microsoft Teams will now have this feature switched on by default as of 8th February 2021.

The notice, which was originally posted in December from Microsoft, alerted users that Guest access in Microsoft Teams will be automatically switched on by default.

What is Guest access in Microsoft Teams?

Guest access is exactly as it sounds – the ability to connect to external users in Teams outside of your organisation. During the 2020/21 pandemic, this feature may be proving incredibly useful for those having more online meetings than usual.

With this feature, you can provide access to teams, resources, chats, documents in channels and applications to guests, while still maintaining control over your corporate data.

A guest is someone who isn’t an employee, student, or member of your organisation. They don’t have a school or work account with your organization. Examples include:

  • Corporate partners
  • consultants
  • suppliers
  • vendors

Anyone who is not part of your organisation can be added as guest in Teams. This means that anyone with a business account (that is, an Azure Active Directory account) or consumer email account (with, or others) can participate in Teams, with access to teams and channel experiences.

How do I disable Guest access in Microsoft Teams?

To disable Guest access within Microsoft Teams, Microsoft recommend the following:

‘If you want guest access to remain disabled for your organization, you’ll need to confirm that the guest access setting is set to Off instead of Service default.’ – This can be configured in the ‘Microsoft Teams Admin Center’ under ‘Org Wide Settings’. (Only administrators can do this for your organisation).

Do you have more useful information about Microsoft Teams?

We’ve written a blog post about how users can get the best out of communicating with external users with Microsoft Teams; these features have been very helpful to businesses during the pandemic.

We have another blog post here about how Teams, although useful, shouldn’t be mistaken for your company’s intranet.

Teams is a great way to communicate with colleagues – we have a guide here about wellbeing and how this technology (among others in Microsoft 365) is contributing towards better staff wellbeing.
