Adding a new email domain

[lafleur1977]

Hello,

 

Just a query about domains and possibly adding a domain to our 365 tenancy.

 

Our school has 2 domains, one for our school website http://www.###.com & for our AD and 365 tenancy we use ###.lancs.sch.uk

 

I was wondering how easy it would be to add the school website http://www.###.com domain to 365 so our users can use both domains to send and receive - is something like this possible?

 

Thanks

Rather easy.

 

Add the domain to 365 and it will create a TXT record for verification.

Add this to your DNS records on the domain to prove ownership.

 

Once added you can then add users with either domain or add the other domains as an alias

This sounds too easy, but it is actually that easy.

Thanks @snagrat & @Jawloms - that does sound easy! I've also just thought we have Sophos email protection setup so might need to think about that too, but if we just want to use the extra domain as an alias I presume that shouldn't be an issue.

Dont forget to setup DKIM, SPF, DMARC and autodiscovery CNAME

And MX!

I suppose the bit I didn’t mention was after verification you will get more DNS records to add.

 

The wizard will check these are set correctly for you.

 

(But good suggestion regarding DMARC that isn’t included in the above wizard)

Hmm need to do this too well out of practice with domains and dns records :S

IDK if MS promotes MTA-STS at all, but that's another one to add alongside SPF, DKIM and DMARC whilst you're at it. It works to ensure that inbound emails are encrypted in transit from the sender - https://www.ncsc.gov.uk/collection/email-security-and-anti-spoofing/using-mta-sts-to-protect-the-privacy-of-your-emails.
