The driver supports multiple domains. By default, while installing exchange some domains are prepared for exchange provisioning. If there are other domains that need to be prepared for exchange provisioning, you must prepare them before configuring the Multi-Domain Active Directory driver. This step creates additional containers and security groups, and sets permissions so that Exchange can access them.
Before setting up the domains for exchange provisioning, ensure that you set the required permissions for the user who provisions the domains.
To prepare all the domains in the forest, run the command:
Setup.exe /PrepareAllDomains /IAcceptExchangeServerLicenseTerms
To prepare only selected domains in the forest, run the command:
Setup.exe /PrepareDomain:<FQDN of the domain you want to prepare> /IAcceptExchangeServerLicenseTerms
