By default, you have probably noticed it can take up to 3 hours for a change to be in your on-premise environment to be replicated to your Office 365 environment.  In organizations that have a smaller amount of users, you can change the frequency of the synchronization schedule to replicate the changes to Office 365 more quickly.

1. Login to the server with the DirSync application (Windows Azure Active Directory Sync)
2. Open up Notepad as an Administrator
   
   
3. Open the folllowing file
   1. C:\Program Files\Windows Azure Active Directory Sync\Microsoft.Online.DirSync.Scheduler.exe.config
      
      
4. Change the SyncTimeInterval to how often you want the tool to be run.  The time is in hh:mm:ss
   1. For example, to change a sync frequency to every 15 minutes
      1. Change <add key=”SyncTimeInterval” value=”3:0:0″ /> to <add key=”SyncTimeInterval” value=”0:15:0″ />
         
5. Save and Close Notepad
6. Restart the Windows Azure Active Directory Sync Service
