How to connect your Microsoft 365 emails to your domain

Microsoft 365 is one of the most popular email platforms right next to Google Suites or Google Workspace. If you have recently published a new website and have changed your nameservers to Siteground or a new host, chances are you have to update your DNS to work with your Microsoft Emails. If you did this before pointing your domain over to the new host or website, then you should be in the clear. However, if you only updated the nameservers, it is crucial to update the rest, otherwise, your emails won’t be working with your domain.

Thankfully, Siteground has awesome customer support and they have provided me with the exact records to update.

To do this, navigate to your DNS Zone Editor. In Siteground, go to your website tools > Domains > DNS Zone Editor> then at the top where it says Create a New Record click on the type of record you want to create.

First are the CNAME records. Click on CNAME and enter the following records. Leave the TTL as is. Each line is a new record:

  • Name: autodiscover Resolves to:
  • name: lyncdiscover Resolves to:
  • name: sip Resolves to:
  • name: msoid resolves to:
  • name: enterpriseregistration resolves to:
  • name: enterpriseenrollment resolves to:

If you get an error message saying a record with that name already exists, check to see if it is the same value. If not, delete it and add the new one. A successful change will show a notification similar to the one below.


Then you need to click BACK to update the MX record. Make sure to change “yourdomain” to your actual domain minus the “.com”. If there is a field missing in the settings below just ignore the field

MX record:

  • priority: 0 destination:

TXT records:

  • value: v=spf1 -all
  • value: MS=ms96180165

SRV records:

  • Service : sip Proto: TLS Priority: 100 Weight: 1 Port: 443 TTL: 1 hour Target:
  • Service: sipfederationtls Proto: TCP Priority: 100 Weight: 1 Port: 5061 TTL: 1 hour Target:


The last step is to remove the old MX records (if any). If you are using Siteground Hosting, they’ll look like this:
