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?
Kris Kaiser With the September 2020 update to Office 365 Hybrid Configuration Wizard it is now possible to set up multiple Office 365 tenants with a single Exchange organization. Please refer to this article which describes a similar set up Single On-Premises Exchange to Multiple Office 365 Tenants - Part 2 - Technically Possible
