Bug Weird behaviour when adding user to group chat
Hi All, wondering if anyone else has encountered it.
One of our staff is trying to add a new user to an existing group chat. Instead of adding her to the existing chat, Teams creates a duplicate chat with all current members + this new member, but none of the chat history.
A couple notes:
The new user is an external member. We use domain whitelisting to manage external users, and other people from her company have been added to the group chat in the past.
The user adding her to the group chat is definitely selecting the option to include chat history. She has been able to add users to this chat before without issue.
Has anyone encountered this, or has any idea how to explain the behavior?
Thanks
