Problem
If you are using Azure AD Connect, (AAD Connect) to sync your on-premise Active Directory with Azure AD (i.e. for Office 365), then there may be times when you need to manually ‘force a replication’ because by default it’s going to take 30 minutes between each normal ‘delta replication’
Solution
If you are directly on the server that’s running Azure AD connect, then use the following PowerShell. If you Don’t know which server is running AD connect the see the following link;
Locate Your Azure AD Connect Server
Firstly you need to add in the correct module, (you only have to do this once). Though the module should be already installed on the Sync server, let’s not tempt fate and check. (You can also use Get-Module to view installed modules).
Import-Module ADSync
Note: If you get an error you may need to run Import-Module “C:\Program Files\Microsoft Azure AD Sync\Bin\ADSync\ADSync.psd1”
Then to Manually Force a Synchronisation;
To Perform a FULL Sync Start-ADSyncSyncCycle -PolicyType Initial To Perform a (Normal) Delta Sync Start-ADSyncSyncCycle -PolicyType Delta
You can view the Sync settings with;
Get-ADSyncScheduler
But I don’t like that, I prefer to watch synchronisations going on on the ‘Syntonisation Service Manager’ console, you can spot and troubleshoot errors in here also 🙂
Note: To Troubleshoot Sync errors, see the procedure I use in the following post;

Force an Azure AD Connect Synchronisation From Another Server
Use the following syntax;
Invoke-Command -ComputerName AD-Connect-Server-Name -ScriptBlock {
Import-Module ADSync
Start-ADSyncSyncCycle -PolicyType Delta
}
Disable and Enable Azure AD Sync
Disable Set-ADSyncScheduler -SyncCycleEnabled $False Enable Set-ADSyncScheduler -SyncCycleEnabled $True
