We have just recently enabled Supervised chat on Microsoft Teams through the admin portal. Students have been assigned a restricted chat policy. This works to disable students from starting new chats with each other. Old chats that were started before Supervised chat was enabled, however, are still able to be used.
Is there any way to disable students with restricted messaging permissions from using old chats, while still allowing new chats with Full users? Or perhaps a way to mass delete chat from a specific group of students, while preserving communications with Full users?
We have enabled supervised chat recently but having the same issue of not able to remove the existing chat windows between restricted users. Can I ask if you have enabled or disabled chat for the restricted users in the Teams messaging policy before enabling the supervised chat?
