With this article we want to draw your attention to the fact that Microsoft, in December 2020, announced a Major update which is important for all of our Atlas clients.
Your IT team should have received an email with a "Message Center Major Change Update Notification" already mentioning the time window when Microsoft will turn on Guest access in Microsoft Teams by default if your IT team has not configured this setting. This will bring the Teams Guest capability into alignment with the rest of the suite, where the setting is already on by default.
How this will affect your organization?
When this change is implemented, if you have not already configured Guest access capability in Microsoft Teams, the capability will be enabled in your tenant automatically. With Guest access enabled, you can provide access to teams and other resources to people outside your organization while maintaining control over your corporate data.
What do you need to do to prepare?
Prior to this change taking effect on February 8th 2021, if you want Guest access to remain disabled for your organization, you will need to confirm that the Guest access setting is set to "Off" instead of "Service default". Instructions for how to configure the Teams Guest access settings can be found here: Teams guest access settings
