Azure AD syncs passwords every 2 minutes and syncs object changes every 30 minutes.

Get-ADSyncSchedulerAzure AD sync scheduler settings:
- AllowedSyncCycleInterval: It specifies Azure AD’s minimum synchronization interval. This is the maximum supported synchronization frequency.
- CurrentlyEffectiveSyncCycleInterval: This displays the schedule currently in effect.
- CustomizedSyncCycleInterval: Configure this parameter, if you want the scheduler to operate at a frequency other than the default 30 minutes.
- NextSyncCyclePolicyType: It’s either Delta or Initial. Specifies whether the next run should merely process delta changes or do a full import and sync. The latter would reprocess any new or updated rules.
- NextSyncCycleStartTimeInUTC: This specifies the start time of the next sync cycle.
- PurgeRunHistoryInterval: Displays the time operation logs should be kept. Review these logs in the synchronization service manager. The default storage time is 7 days.
- SyncCycleEnabled: This specifies whether the scheduler is conducting the import, sync, and export processes as part of its normal operation.
- MaintenanceEnabled: This setting shows, if the maintenance process is enabled. It makes updates to the certificates/keys and deletes operations log.
- StagingModeEnabled: Indicates whether staging mode is enabled. When this setting is enabled, it disables exports but allows import and synchronization.
- SchedulerSuspended: This setting is set by Connect during an upgrade to temporarily block the scheduler from running.
