Adding Exchange Multi Tenant to an existing Exchange Network

  • 772

I currently have an Exchange 2010 SP1 server in house, and due to some changes, it looks like i will need Multi Tenant support for a few extra domain names. Looking at the documentation i have found so far, it only mentions multi tenant support when upgrading from 2010 RTM -> SP1, and not what you do if you have already got 2010 SP1 installed.

So, from what i can gather, i have a few options:

  • Install a new Exchange server with Multi Tenant support and migrate DBs over
  • Back everything up and start again
  • Something else...

Any suggestions would be greatly appreciated...

Thanks.

  1. Do you really need Multi-Tenant suuport or do you only need to add some additional domains to your Accepted Domains? Are these domains for different customers/users who need segregation or are these for your company alone and you're just adding some new domain names that the company has acquired?

    You can't add Exchange 2010 in hosting mode to an existing organization. You will need to stand up a new forest and Exchange organization and migrate the user mailboxes.
