How to add a domain and users to a current account

I want to add another, second, domain to our current account.  The 8 users that use this account also use the the current domain address for their email, so they will end up with 2 email accounts.  I...

Hi BoxOfFrogs,

 

It is not clear from your question that are you using Office 365 (Exchange Online) or not. If you are using Office 365, all that jcgonzalezmartin said is correct.

  1. You first need to add the domain to Office 365. To do this, you need to be a Global Admin and have access to the DNS server of the domain. Then just add new email addresses as aliases.
  2. There is no need for a hosted POP provider anymore, you can route your email to Office 365
  3. Yes

If you are not using Exchange Online:

  1. Depends on your email system. You can add to outlook as many Exchange accounts you want to.
  2. I think the billing would be same
  3. Yes

Thank you. Yes, I should have been clearer we are currently using Office 365 exchange online for our email. We have an E3 Enterprise account and about 30 users.

Of these 30 users, eight of them primarily do work for for another one of our companies. They want to be able to both send and receive email from that companies domain. They currently do this using a pop account. We would like to move that domain under the umbrella of our Office 365 for simplicity's sake. So they would be receiving mail from both companies domains.

    Okay. Well, you can send mail from a mailbox using one email address. So, if you want to send using two email addresses, you need to have two mailboxes. You can either create a second full mailbox for those users, or create one shared mailbox per user with other email address (as someone suggested earlier). From technical point-of-view, the only difference is that shared mailbox does no require a license.

    The steps are:

    1. register your other domain to Office 365
    2. create a shared mailbox to the users in question and "add" users to shared mailbox
    3. change the MX and SPF records for the other domain to point to Office 365

    The shared mailboxes will appear automatically to users' Outlooks in <30 min or so. After that, when sending email, they can choose which email address to use.

      OK, so the shared mbx eliminates the need for licenses, correct?

       

      So in my scenario I have the current "company1.com".  I add "company2.com".  

      I have 2 users in both company1 and company2; bill@company1.com, melinda@company1.com, bill@company2.com, melinda@company2.com.  I then create a shared mailbox called everybody@company2.com.  I make Bill@company1.com and Melinda@company1.com members.

       

      In the mbx scenario bill and melinda each have their own, private, email in company1.  But they can each see the others email, both sent and received in company2, correct?  If I (the customer) sends email to Bill@company2.com, how does that get routed into the mbx everybody@company2.com?  Is it because I have made bill@company1.com a member of the mbx everybody@company2.com?  Will Bill have manually select the From address each time he replies or will the reply come from everybody@company2.com?  I don't understand how it would know that email for Bill@company2.com belongs to Bill@company1.com

       

       

      This may not be an issue, I need to check with the customer.  In fact it may be an advantage.  But if not then I will need to purchase (or allocate) 2 licenses, one for Bill and one for Melinda, correct?  I wish there was a way to test this before hand, I do NOT want an email disaster on my plate.

       

      Sorry if I'm being too **bleep** about this, but I would like to understand it.

        Hi,

         

        Sorry for being a bit unclear. Using the shared mailbox doesn't remove the need for licenses as such, but you don't need as many of them. A shared mailbox doesn't need a license, but the user who is using that, needs one.

         

        So this is what you need to do for Bill. 

        1. You need two mailboxes:

          1. bill@company1.com: Normal mailbox (i.e. a normal license)

          2.  

            bill@company2.com: Shared mailbox (i.e. no license)

        2.  Give only bill@company1.com access rights to bill@company2.com:

        This way the new bill@company2.com mailbox will appear to Outlook of bill@company1.com in <30 min or so. So no need to forward or anything and the reply address is automatically correct one.

         

        Hopefully this clarified my proposal :)
