You can have multiple domains in the same Exchange Online tenant, and as long as they're "verified", you can assign aliases associated with them to your users/mailboxes. For example, a user can have a user@keyman .com and ******@anotherdomain.com addresses, and receive messages directly on both. As long as you add the additional address(es) to the same user/mailbox, no extra licenses are required.
Hi @Chingis Rustemov
Yes, agree with michev, the question you asked above is supported. We could refer to the introduction from Microsoft: Domains FAQ
Can I add custom subdomains or multiple domains to Microsoft 365?
Yes, typically you can add up to 900 domains to your Microsoft 365 subscription.
When you add multiple domains to Microsoft 365, you can host any of the services (like email) on any of the domains you've added. When you change your email to Microsoft 365, by updating a domain's MX record, ALL email sent to that domain will start coming to Microsoft 365.
And the steps to perform this operation: Add a domain to Microsoft 365

Hello Koala26735,
Thanks for reaching out to the Microsoft Community. We are happy to assist you.
Based on the information provided, it is indeed possible to use a single Office 365 subscription to manage multiple domains and email addresses. However, there are some important considerations to keep in mind:
- Multiple Domains in a Single Tenant:
- You can associate multiple domains with a single Office 365 tenant. Domains Frequently Asked Questions | Microsoft Learn.
- This allows you to use different domain names for email addresses and websites under the same subscription.
- However, it’s essential to understand that the subscription remains tied to a single Microsoft account.
- Adding Additional Domains:
- To set up additional domains, you’ll need to add them to your Office 365 tenant. Add a domain to Microsoft 365 - Microsoft 365 admin | Microsoft Learn.
- Once added, you can assign email addresses using the new domain names and manage them all from the same Outlook desktop app.
- User Licenses and Recommendations:
- While you can have multiple domains, remember that you are still limited to the number of user licenses included in your subscription.
- Additionally, it’s generally recommended to have separate Office 365 tenants for different businesses rather than trying to manage everything under a single account.
In summary, with proper setup and configuration, you can effectively use a single Office 365 subscription to manage multiple domains and email addresses. However, be aware of the limitations and consider separate tenants if needed.
If you have any further questions or need additional assistance, feel free to ask!
There are many Bus sub licence types, the MS Account associated with O365 will be named as per that bus name
Hello everyone!
We have a client that has two domains in their M365 tenant. Presently all users are leveraging the main domain name for their username and email address. There are a few shared mailboxes in the tenant that leverage the second domain, along with a small subset of users who have an alias for the second domain and occasionally receive an email to that alias.
They are now reaching a point where this second division is growing and the small subset of users need to both send and receive emails from the primary domain and the secondary domain, so a user Joe Demo would have a setup like this, [email protected] and [email protected]. Initially this was great when it was just an alias and they were not sending from the second domain, but now trying to setup a solution for them we can't figure out what the best way forward is.
The first option we thought of was separating this out into a second tenant but then we would need additional licenses for Dropsuite and Defender P2 and we will do this if necessary but wanted to see if anyone else knows of a way we can keep these under a single tenant.
Some additional thoughts we had were to create a shared mailbox for each of the users with domain2 and delegate the user to that shared mailbox but M365 doesn't allow us to create a shared mailbox and says "Email address not available because it's used by Joe Demo". We could potentially do something like [email protected] and propose that to the client but they have been pretty adamant about keeping it the same across both domains.
We also know that you can now send email from an alias and that is also a potential solution but has some limitations around usability and training. Users would need to make sure they are always updating the Send As in their emails and may not be available on mobile etc.
I wanted to see before we go the route of proposing a second tenant if there is some other way to accomplish this that we are missing, or if we should work to convince them to use a different email for the secondary domain and keep them as shared mailboxes?
Thank you all!
Ever since I got my home office 365 family subscription, I had my eye on the option for the personalized domain name in outlook. However, according to Microsoft, only domains hosted with GoDaddy could be connected and used.
Now, to be fair, GoDaddy is probably a fine company to use for DNS hosting, but I don't want to switch registrars.
But I pieced information together how to get the personal domain in outlook without even using or switching to GoDaddy and use my current hoster!
-
Go to outlook, the premium settings and choose the option to "get started" with a personalized domain.
-
Click the option to buy a new domain with GoDaddy, and a new window opens
-
Copy the URL of the new window that opens, it should look like this: https://domainconnect.godaddy.com/v2/domainTemplates/providers/outlook.com/services/personalizedoutlookemail/apply?mxRecordValue=XXXXXXXXX&state=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX..... The part that you need is "mxRecordValue=XXXXXXXXX" The XXXXXXXXX is the unique ID for verification used in DNS
-
Go to your own domain DNS settings and add the following settings replacing XXXXXXXXX with your ID found in step 3.(Note, these settings are for TransIP specific, your own DNS manager may use a different syntax!)
| Name | TTL | Type | Value |
|---|---|---|---|
| @ | 1 hour | MX | 0 XXXXXXXXX.pamx1.hotmail.com. |
| @ | 1 hour | TXT | v=spf1 include:outlook.com -all |
| autodiscover | 1 hour | CNAME | autodiscover.outlook.com. |
| _dmarc | 1 hour | TXT | v=DMARC1; p=none; |
| _domainconnect | 1 hour | CNAME | _domainconnect.gd.domaincontrol.com. |
| _outlook | 1 hour | TXT | XXXXXXXXX |
The dot on the end of the external domains is not a typo!
5. Return to the premium settings in outlook to set your custom domain.
6. Choose the option "I already have a domain"
7. Enter the domain you just configured
8. You have to click to login to GoDaddy, do this, but just exit the page it goes to.
9. Congratulations it should now say you connected the domain with GoDaddy!
Now, to be fair, GoDaddy is probably a fine company to use for DNS hosting
Narrator: they weren’t.
Thank you so much!
I recently switched from Microsoft 365 Business for my wife and I (and home labbing purposes) to Office 365 family, and I hated losing our personal domain. I use Google Cloud's DNS (not Google Domains), so I had to make sure I put double quotes around all the TXT records, but it worked perfectly!
