Multiple Exchange Org in hybrid

Hi all,

we have the following configuration.

One tenant.

Two companies each with their AD Forest and Exchange Organization.

The two forest are in trust with each other.

On Forest A we have the EntraID Connector that is already configured to sync users from both the companies.

On each forest there's an Exchange organization completely on-prem each responsible for their namespace.

Now we'd like to configure both the exchange organization in hybrid mode with the common Tenant and perform the mailbox migration to exchange online to have the users of both companies to be able to share calendars, resources atc.

Is that possible to configure exchange Hibryd on two exchange Org to the same tenant ?

Are there any issues we must be aware of ?

thanks

SC
