If you are permitted to work offline, your local cache of rights is updated by synchronizing to connected servers. This will allow you to keep working with sealed documents even when you are disconnected from the network and cannot contact the server. Typically, your cached rights allow you to keep using documents for several days before being required to contact the server.
Synchronization is almost completely automatic. Typically, it runs daily during standard office hours, but the schedule is controlled by the administrator of the server.
If synchronization fails for any reason, the application displays a failure message and automatically retries at intervals.
You can initiate synchronization manually at other times: for example, if someone notifies you that your rights have changed, and you want to synchronize immediately rather than wait for the automatic process. See Section 7.4, "Synchronizing Your Rights Manually".
