Hi there, as an administrator is there any possibility in Mattermost to block 1to1 conversations and only allow group conversations ?

Hi @StephaneJ,
I don’t think there is a setting to disable them, but we have a feature request issue open here that you can upvote: https://mattermost.uservoice.com/forums/306457-general/suggestions/12954666-disable-direct-messages.
