Create separate retention policies for 1:1 chat and Team / Channel chat
In Skype for Business, there's an option to log or not log messages, and all one to one or one to many messaging threads are treated as ephemeral messaging if logging is disabled.
In teams, not logging or retaining messaging in a Team or a Channel reduces the value of the tool. Currently, retention can be configured for chat to team or channel messaging, and the same retention level is applied to all messaging. (30 day minimum)
It would be great if 1:1 or 1:many chats could be treated as ephemeral messaging, and teams / channel chat could be set under a separate retention.
