    Thank you very much.

  2. Mohammed,

    Thank you for the information. I am having difficulty figuring out how to make each client’s mail have an appropriate header.

    Can the system be set up so that each tenant appears to have their own email. IE Set the “Sent By / Received From” server name for each of the hosted domains? Then how do you deal with the requirement that mail servers have an RDNS record?

      Hosted exchange . All email going to sent from same server .
      Just we are segregating users .
      Where one tenant cannot see the other .

  3. Hi
    We currently have a 2010 SP2 multi-tenant hosted enviroment. When setting this up i know there was a lot of stuff to do with setting up each Tenant to make sure they had no access to other tenants etc in the organisation. We now currently have Powershell scripts that we run to create new tenants and new users within those tenants.

    Is there anything special that needs to be done to Active Directory here as i notice this guide has none of that information?

  4. Hi dear

    What about the password sync? means the local AD on the tenant how will be sync with their Ou ?? is there and power shell script can be installed on both side ??

  5. Pretty! This has been a really wonderful article.

    Thank you for providing this information.
