| Why customers use this | Professional business email and collaboration tools; Works well for companies already using Outlook and Office apps |
| Records to expect | Microsoft 365 commonly requires a TXT record for verification, MX records for mail, and may also require CNAME, SRV, SPF, and DKIM-related records depending on the services you enable. |
Before you start
Have access to both your AEserver Client Area and your account at Microsoft 365.
Know whether you are connecting the root domain (example.com), a subdomain (such as www.example.com or shop.example.com), or both.
Take a quick screenshot or copy of any current DNS records before editing them, especially if the domain already has a live website or email service.
Step 1 – Get the DNS records from Microsoft 365
1. Sign in to the Microsoft 365 admin center.
2. Go to Settings > Domains or the domain setup wizard.
3. Add your domain and copy the verification TXT record.
4. Continue through the wizard and copy all required DNS records for Exchange Online and any other services you use.
Step 2 – Add the records in the AEserver Client Area
1. Sign in to your AEserver Client Area.
2. Open Domains and select the domain.
3. Open DNS Management.
4. Add the TXT verification record and save.
5. After Microsoft confirms ownership, add the MX, CNAME, SRV, and SPF records the wizard provides. Do not delete existing mail records until you are ready to switch mail service.
6. If DKIM is enabled later, add the extra CNAME records Microsoft gives you.
Step 3 – Verify and finish
1. Return to the Microsoft 365 admin center and complete the domain check. Then test email, Outlook autodiscover, and Teams or other services if used.
2. Allow time for DNS propagation. Many changes appear within a few minutes or hours, but full propagation can take up to 24-48 hours.
3. Once the service shows as connected, test the live result. Open the website, send a test email, or visit the exact subdomain you connected.
