Rabia Noureen


MC400204 – Updated November 18, 2022: Microsoft has updated the rollout timeline below. Thank you for your patience.

Teams users will now see an invitation pop-up to accept or block an external user when receiving new chats from external users.

This message is associated with Microsoft 365 Roadmap ID 94646

When this will happen:

Microsoft will begin rollout for this feature in mid-August and expect rollout to be completed by mid-January (previously mid-November).

How this will affect your organization:

When receiving a new one-on-one chat from an external user, Teams users will receive an invitation to accept or block the external user. This also provides the ability to block external users at any point, which revokes access to presence and incoming messages.
