Azure AD Connect On-Demand Sync

If you've just installed Azure AD Connect or upgraded from a different directory sync engine like FIM, MIM or even the ancient DirSync, one of the first things you realize as an admin is that the sync engine is MUCH faster and consistent than the previous versions. The changes sync automatically every 30 minutes without you having to do any manual override. However, there still may be some cases when you'd like to force a directory synchronization cycle IMMEDIATELY. How do you do it in the Azure AD connect? The PowerShell cmdlets you used earlier have changed. Welcome to the new world. 

If you use AAD Connect Server, here's how you can use a forced synchronization - 

To initiate a Delta Sync, open Windows PowerShell and run:

Start-ADSyncSyncCycle -PolicyType Delta

To initiate a Full Sync, open Windows PowerShell and run:

Start-ADSyncSyncCycle -PolicyType Initial

If the commands are not available, try to load up the below PowerShell module:

Import-Module "C:\Program Files\Microsoft Azure AD Sync\Bin\ADSync\ADSync.psd1"
