The AD Update option forces the SBC to query AD directly to obtain updated records (rather than following the parameter set in the AD Update Frequency field in the SIP Signaling Group). This option is available for each Signaling Group configured with Office365 w/AD PBX as the Interop Mode.
For details on configuring the Interop Mode, see Creating and Modifying SIP Signaling Groups.
