what DNS settings do I need to change (and where) when I close my shop bu want to keep my exchange email?

Question

My small business is set up with 3 microsoft exchange email addresses and we DID have a big commerce online shop.

The Name Server records were directed to Bigcommerce.

I need to keep the email accounts on exchange. What settings do I need to set up at my domain host and then on exchange to continue with just the emails?

Thanks for any assistance you can provide

Hi,@Andrew Mason

Thanks for posting your question in the Microsoft Q&A forum.

o ensure your Microsoft Exchange email addresses continue to function, you'll need to adjust your DNS settings at your domain host. Specifically, you need to make sure that your MX (Mail Exchange) records and any other necessary DNS records are correctly configured to point to Microsoft's Exchange servers. Here are the steps you'll typically need to follow:

Log in to the DNS management panel and add the following key records:

1. MX Record (Mail Server Routing)

• Host/Name: @ (or leave blank for the root domain)
• Record Type: MX
• Priority: 10 (adjust as needed)
• Target/Value: mail.yourdomain.com (replace with your Exchange server’s domain)
• TTL: 3600 (default)

2. A Record (Exchange Server Public IP)

• Host/Name: mail
• Record Type: A
• IP Address: Enter your Exchange server’s public static IP (e.g., 203.0.113.5)
• TTL: 3600

3. Autodiscover Record (CNAME)

• Host/Name: autodiscover
• Record Type: CNAME
• Target/Value: mail.yourdomain.com
• TTL: 3600

4. SPF Record (Anti-Spam)

• Host/Name: @
• Record Type: TXT
• Value:

v=spf1 ip4:your_exchange_public_ip ~all  

Example: v=spf1 ip4:203.0.113.5 ~all

5. Optional: Reverse DNS (PTR Record)

• Contact your ISP or hosting provider to set up a PTR record for your Exchange server’s public IP, pointing to mail.yourdomain.com to improve email deliverability.
