With the ESI Exchange Integration, ESI supports storage-provisioning tasks for your Exchange on-premises organization or forest. The on-premises forest includes all Exchange mailbox servers managed by the organization on the premises. ESI does not support Exchange online forests.
Exchange mailbox servers host mailbox databases and provide e-mail storage and advanced scheduling services for Microsoft Outlook and Microsoft Office Outlook Web App users. Exchange limits a single DAG to a maximum of 16 servers, so that is the maximum supported in ESI.
You can perform the following Exchange tasks in ESI:
You can also use the Exchange cmdlets in the ESI PowerShell Toolkit to automate storage-provisioning tasks for Exchange.
