Restrict direct messages

Organization administrators can configure two types of permissions for direct messages:

Who can authorize a direct message conversation. To send a DM, the recipients must include at least one user who can authorize the conversation (the sender or someone else).
Who can start a direct message conversation.

These permissions can be granted to any combination of roles, groups, and individual users. They are designed so that users can always respond to a direct message they’ve received (unless organization permissions change). They also provide a lot of flexibility for managing DMs in your organization. For example, you can:

Prevent 1:1 DMs between guest users.
Allow members to respond to DMs from an admin or moderator, but not to start DM conversations.
Disable direct messages altogether.

Regardless of how these settings are configured, users can always send direct messages to bots and to themselves.
