Office 365 Multi Tenant
I currently have a single Exchange 2010 server on premise within a singel AD forest and non-routeable domain (xxx.domain) Within this structure I have multiple sub-tenants setup as separate OUs with users in each OU having separate email addresses. On premise tenant A = xxx@contoso.com - On premiste tenant B = xxx@fabrikam.com
I have this already configured in Office365 Hybrid mode for one of the existing tenants but now looking to migrate another on premise tenant to Office 365.
Can I create a new Office365 instance for this sub tenant and use a separate AD Connect instance to sync only those users to the new Office 365 instance? Can I setup a second Hybrid Mode configuration to enable seamless mailbox moves?
