Description
Does Recovery Manager for Exchange require the Active Directory Lightweight Directory Services (ADLDS) Role?
-
Resolution
1. AD LDS is required by Recovery Manager for Exchange for restoring Exchange backups using emulation where the original Exchange server is no longer available. RMEx creates an AD LDS instance on the machine and creates a “phantom” Exchange server in it.
- If there is no plan to restore backups using emulation or the original Exchange server is still available, the AD LDS role can be uninstalled.
2. When uninstalled and using emulation you will see the following in the QuestSoftware.RecoveryManager.ExchangeEmulation.log:
