Restriction: The Lock Group feature is available only in Premium and Enterprise groups.
Location in desktop browser: Left menu > Admin > Preferences > Notices
Location on mobile device: Bottom of page > More > Admin > Preferences > Notices
The Locked Group notice can be sent automatically when the group has been locked but someone sends an email to it. To be sent automatically, the notice must be the active notice (set to Active Message). If no Locked Group notice is set to Active Message, none will be sent.
Note: Groups.io automatically locks any subgroups that were created in:
- A Free group that was created after January 15, 2020 at 9:00 a.m. U.S. Pacific Time, then upgraded to Premium, then later downgraded back to Free
- A trial Premium group that is downgraded to a Free group
Those subgroups are locked until the Free group is upgraded again.
