Will using "start-ADSyncSyncCycle -PolicyType Delta" provide immediate and fastest results?

The Power of start-ADSyncSyncCycle -PolicyType Delta

Yes, using the PowerShell cmdlet start-ADSyncSyncCycle -PolicyType Delta will indeed execute a delta sync cycle in Azure AD Connect. This method is considered to be more efficient and faster than a full sync, primarily because it only checks for changes in the directory since the last synchronization.

However, the actual speed of the synchronization process can vary based on several factors. One crucial factor is the amount of changes that need to be processed. While a delta sync is designed to be quicker than a full sync, processing a large number of changes can still take some time.

Therefore, while using the "start-ADSyncSyncCycle -PolicyType Delta" cmdlet can provide immediate synchronization by checking for recent changes, the speed of the process may not always be instantaneous. It's important to consider the specific scenario and the size of your environment when determining the overall efficiency and speed of the delta sync cycle.

In general usage, a delta sync is likely to be faster than a full sync, but it may not always be the absolute fastest option depending on the circumstances. Nonetheless, it remains a valuable tool for maintaining up-to-date synchronization in Azure AD Connect.
