Teams users are now able to send messages to themselves with the same chat functionality as with chatting with others. Users can start a chat with themselves by starting a new chat and typing their name into the “To:” field.
Previously, users weren’t able to directly send themselves messages. Some were starting a meeting with themselves and using the meeting chat as a self-chat. Another workaround was if everyone in a group chat left, and the user was there alone. These will continue being part of the experience, but they are different from a self-chat. Self-chat can also be accessed from the people card.
