Good day for everyone

i'm just start using Zimbra, and i have this doubt and I really like to have an answer

In the company where I work, they decide to expand and to create a decentralied administration of the mail server
For such point in the central there a Exchange server under the domain ""
Now they want to open a new office in another place and they want that in there they have their own zimbra mail server also under the domain "" and be able to send a receive messages as if they were in the central
Is this configuration possible with zimbra community?
I need to know if this is possible and what is the steps to do this configuration becouse i'm in charge of the new office installation and i don't know how to do it

Is there a guide or a wiki or something that could help me
