-> Once network connectivity to the Azure File Sync service is restored, sync might not resume immediately. By default, Azure File Sync will initiate a sync session every 30 minutes if no changes are detected within the server endpoint location. To force a sync session, restart the Storage Sync Agent (FileSyncSvc) service, or make a change to a file or directory within the server endpoint location.

-Sync sessions fail with one of these errors because either the volume has insufficient disk space or disk quota limit is reached. This error commonly occurs because files outside the server endpoint are using up space on the volume. Free up space on the volume by adding additional server endpoints, moving files to a different volume, or increasing the size of the volume the server endpoint is on. If a disk quota is configured on the volume using [File Server Resource Manager](/windows-server/storage/fsrm/fsrm-overview) or [NTFS quota](/windows-server/administration/windows-commands/fsutil-quota), increase the quota limit.
