MULTIPLE Exchange Sites

We have a large customer that has several exchange SITES throughout NZ, these are all seperate. Unity as we understand it is designed to reside within a SITE, and can connect to multiple exchange servers within that site. <br><br>My question is: Can we install UNITY on an exchange server, in its own site and organisation. Can we then connect somehow this Unity box (and organisation / site) to service MULTIPLE Exchange Sites ? - eg ABC corp, and XYZ Corp ? No doubt we may have issues with the likes of the all staff directory etc. The aim is to have two customers (distinct) (two sites distinct from the site that homes Unity) using the one Unity box.<br><br>

Re: MULTIPLE Exchange Sites

Hi Dale.

No, you can’t span multiple sites with a single Unity server, irregardless of if they’re in the same organization or not.

We can only log into mailboxes in our local Exchange site, we are unable to log into mailboxes in other sites. We can get messages TO users at other sites and look folks up in the global directory for addressing purposes, however you’d be unable to call into our box and check your messages. MWIs and Notifications would not work either since that requires us to log in to “watch” your inbox for changes. Each site will need it’s own Unity server and you’ll need to use the digital Networking feature to address messages between users.

Re: MULTIPLE Exchange Sites

We have a customer with a similar need. The holding company has 3 separate companies within the same facility and we have the opportunity to create a single site for the multiple organizations with appropriate trusts between the networks. So, we should be able to share Unity across these multiple organizations, correct?

Re: MULTIPLE Exchange Sites

OK, I'm not understanding what you're saying here... you talk about "Seperate orgs" and having everyone in the "same site". Those two statements don't go together.

In Exchange, if you have each of these companies in seperate Sites (or worse, seperate orgs), you will need a Unity for each company. No way to work around that, trusts or no.

Further, if you have three companies all sharing a Unity, there's no way to segment the directory (i.e. they will all see each other's users, can delivery messages to them, transfer to their phones, find them in the alpha directory etc...). Unity does not have a Tenant Services concept at this point so they would all be part of one big directory.
