Your company has a hybrid deployment of Office 365. You discover that some Active Directory user accounts
are unavailable in Office 365. You need to identify why the user accounts are unavailable in Office 365. What
should you do?

A.
Verify the miissetup.log file.

B.
Run the Microsoft Remote Connectivity Analyzer.

C.
Run the Test-OutlookWebServices cmdlet.

D.
Run miisclient.exe.

Explanation:
In a hybrid deployment, user accounts and groups in the on-premise Active Directory are synchronized to the
Azure Active Directory by using the Azure Active Directory Synchronization Tool (DirSync.exe).
When DirSync is installed on a server in the on-premise network, a utility known as the “Synchronization
Service Manager” (miisclient.exe) is also installed in the “C:\\Program Files\\Microsoft Online Directory Sync
\\SYNCBUS\\Synchronization Service\\UIShell\\” directory.
This “Synchronization Service Manager” can help you with managing MS DirSync especially if errors arise.
