multi domain within office 365
Hi,
Don't know exactly how should we cope with domains that we have. We've got three different domains within organization:
- advanfile.com - main company domain for communication with customers, suppliers, etc.
- cprofit.net - product domain, for SaaS solution maintained by us - currently all users in 365 are attached to that domain, as we have been evaluating that service that way. e-mails from advanfile.com were migrated already
- advanfile.pl - legacy local domain - not used anymore, however, older customers may still send e-mails to that domains
Now, we'd like to implement the following scenario:
- advanfile.com - all users within an organization should have ability to receive and send e-mails from this domain
- advanfile.pl - mail sent to user_1@advanfile.pl should be redirected to user_1@advanfile.com. Sending from advanfile.pl not possible
- cprofit.net - functional mailboxes - sales, support, and couple of personal mailboxes - messages received should be redirected to advanfile.com group of users, ability to send e-mails from cprofit.net domain
Domains are registered within office365 and MX and TX records are set, but I do not know how should we proceed. Questions:
- Is it possible to have redirection from advanfile.pl to advanfile.com without the need to create (and acquire and apply additional license) to each user within organization?
- How should I switch main domain - from cprofit.net to advanfile.com - can I somehow change domain for existing users?
- I understand, that for cprofit.net domain, I should create separate users and apply 365 licenses (cheapest e-mail only license)?
Please advise, all comments appreciated.

You can simply add additional email aliases to those users. As in, user John has primary SMTP address john@advanfile.com and additional aliases john@advanfile.pl and john@cprofit.net. You can have dozens of those added, with no additional cost, and any message addressed to any of those will be delivered in the same mailbox. Sending is only possible by the Primary SMTP address by default, so you got that issue sorted too.

OK, so if I want to receive e-mails from different domains, I just create aliases - I checked it and it works.
Additional licenses are needed only if I want to send e-mails from different domains - so each SMTP requires one license?
To change primary address, I will have to create alias for that one, and then set it as a primary address. The question - what about my mailbox - will remain intact if I switch domains?

Yes, a licensed mailbox can only send from one primary SMTP address at a time (without any address rewriting at the transport, etc...). So I believe you would need another licensed mailbox to simultaneously send from another domain (another primary SMTP address). You could keep switching the primary address though.
Yes, create an alias with a different domain and set it as the primary. The mailbox will remain intact. It will have an effect on sign-in and any scheduled Skype meetings, etc.. as indicated by the warning when you switch the primary:
