Touch a conversation label whose synchronization you want to change.
A dialog box for that conversation label opens, with three options:
Sync none Don’t download any conversations that have only this label.
Sync last 4 days Download the previous 4 days (or number of days you set) of conversations.
Sync all Download all conversations with this label.
