Change DirSync Synchronization Frequency

Some organizations need DirSync to synchronize with their Office 365 tenant more frequently than the default 3 hour interval.

Fortunately, this is easy enough to change.

  1. Navigate to the installation directory for the DirSync tool:
    C:Program FilesWindows Azure Active Directory Sync
  2. Edit this file:
    Microsoft.Online.DirSync.Scheduler.exe.config
  3. Search for the line
    <add key=”SyncTimeInterval” value=”3:0:0″ />
  4. Change the value to reflect the interval you’d like to use.  The default is 3:0:0 which is every 3 hours.  Changing it to 0:30:0 would result in a synchronization every 30 minutes.
  5. Save the file
  6. Restart the Forefront Identity Manager Synchronization Service service.

DirSync Now Supports Password Sync

Details here.

​This is great news for new and existing users of Azure Active Directory Authentication including Office 365, InTune, CRM Online, etc.

This feature simulates Single Sign-On by copying the hash data for user passwords from on-premises Active Directory Domain Services Domain Controllers into the Azure Active Directory Authentication Service. It also updates password data into Azure more frequently than it does other metadata such as DisplayName, etc. DirSync will detect when a user changes their password and attempt to synchronize it within minutes.

If you’re running the legacy 32-bit version of DirSync, you must first uninstall the older version, and then install the newer 64-bit version on a differen computer.
