Thread Permissions

Thread starters and admins can control individual thread access

Thread permissions let thread starters (the person who created the thread) and admins control who can access and respond to specific threads. Other recipients cannot change these permissions.

Thread Permissions include:

• Locking changes to the thread details

  • Prevents new users or groups from being added to the thread

  • Prevents the thread name from being change

• Turning off thread replies to make threads read-only

How to Modify Thread Permissions

Only the thread starter or admins can control thread permissions.

• For new threads: Set permissions before sending the thread by clicking the lock icon.

• For existing threads: Change permissions anytime in the thread settings modal by clicking on the thread permissions dropdown.

The thread permissions drop down is multi-select. You can choose to lock recipients, turn off thread replies, or both on the same thread.

Locking a thread

Thread starters, group admins, or workspace admins can lock a thread to prevent changes to the thread recipients and name. When a thread is locked:

• Only the thread starter and admins can add new recipients or change the thread name.

• All other thread recipients can request to add users or groups to the thread, and the thread starter can approve or decline these requests.

Thread starters will receive a request they can approve or decline

Note: Even if a thread is unlocked, only a thread starter can remove users or groups from a thread.

Turning off replies on a thread

Thread starters, group admins, or workspace admins can turn off replies for a thread. When replies are turned off:

• Only the thread starter and admins can reply or change the thread name.

• All other thread recipients can read, react, and share the thread link.

This feature is useful for announcements to a large audience, reducing notification noise.

Profile Badges

When a thread has replies turned off, you’ll see a role badge next to the profile picture for thread starters and admins, both in thread replies and in the thread member list. That way you can easily see who has access to the thread’s permissions.

Message Editor

• For thread starters or admins: A banner above the message editor shows that replies are turned off, but you can still reply based on your role.

• For recipients: The message editor is hidden, and a banner at the bottom states that replies are turned off.
