Hi @Mohammed Gayasuddin,

how we can configure the exchange hybrid with new tenant. if it is already configured with Forest A.

Hybrid deployments with multiple forests is supported.

Please refer to this link for more information: Hybrid deployments with multiple forests

how we can maintain the domanA.com & domainB.com email address in both forest.

You can add another domain as an accept domain (internal relay domain) on your Exchange server.

Then create email address policies and assign the policy to the mailboxes which need to use another domain as their email address domain suffix.
