- The storage space allocation goes from 30 GB to 1 GB.
- Any subgroups are locked.
Exception: If your group was created before January 15, 2020, subgroups will remain accessible because Free (formerly called Basic) groups created before that date were able to have subgroups. This exception applies to free groups created before January 15, 2020 that were upgraded either before or after that date as well as to Premium groups created before that date. - All features become unavailable except those related to sending and managing messages. However, nothing is deleted in case you decide to upgrade again in the future.
Exception: If your group was created before August 24, 2020, the downgraded Free group will retain the calendar, chat, database, member directory, files, photos, poll, and wiki features.
