Additional team and channel-related features and issues within Microsoft Teams for Education
Cannot agree.
All these posts sound like if Microsoft had forced them to add a subject to their chat messages.
But posts in a channel are (in my world) not a quick message but something thought out and informative for the team. Often also starting a thread of chat messages below it.
(Without a new subject line indeed)
I would suggest to use a group chat instead for these complaining users. Maybe this helps?
It is forced though. Users are forced to add an unnecessary subject or then use several more key commands or mouse movement to simply type in, "GOING ON BREAK".
Subject should be OPTIONAL, not a REQUIREMENT to make a post.
Utter non-sense to force users to do MORE work to do the SAME thing.
