By default the Directory Synchronization runs every 3 hours. If you want to increase or decrease the frequency you will need to modify the following file:
C:\program files\Microsoft Online Directory Sync\Microsoft.Online.DirSync.Scheduler.exe.Config
Just open with notepad along with “RunAs” Administrator permission and you’ll see a line that looks like:
<add key=”SyncTimeInterval” value=”3:0:0″ />
By default the SyncTimeInterval is set to 3 hours. If you wanted it to run every 30 minutes you’d change the value to ”0:30:0″. We wouldn’t recommend going any lower than 15-30 minutes.
