We have a requirement to provision a remote office 365 mailbox from On-Premise Exchange. The below link explains more in detail about what we are trying to achieve.
20% of the mailboxes will be on-Premise and 80% will be online. Is there any way from O365/AD/Exchange connector to enable a remote mailbox for an on-prem exchange?
Release : 14.X
Component : IdentityMinder(Identity Manager)
The Office365 Connector can be used in Hybrid mode which would allow for the creation of AD account in the on-premise domain controller and then allow for license assignment via Office365.
However, if you are looking to create a remote Office365 mailbox in a hybrid deployment such as is described in the following link then that is not currently supported by the product
For that, you would need to implement a custom solution perhaps via PX Policies that invoke the PowerShell cmdlet mentioned in the article.
