Manipulate Email Record For Free

It can take up to 72 hours for the new records to update through the system. During this time, mail sent to your domain might bounce. While there's no way to avoid email bouncing entirely, there are steps you can take to avoid it.

External DNS records required for email in Office 365 (Exchange Online) Email in Office 365 requires several different records. The three primary records that all customers should use are the Autodiscover, MX, and SPF records.

A DNS 'mail exchange' (MX) record directs email to a mail server. The MX record indicates how email messages should be routed in ance with the Simple Mail Transfer Protocol (SMTP, the standard protocol for all email). Like CNAME records, an MX record must always point to another domain.

If you change the A record that the MX record refers to, that will change your mail server. If your MX record points to some mail server outside your domain, such as Microsoft's mail servers (as seems to be the case, per your question), then changing your A records will have no effect on it.

The Domain Name System (DNS) is a directory used by SMTP to convert a name, such as renovations.com, to a list of servers that can receive connections for that name and to find the IP address of a specific server.

Type "nslookup". Your computer's DNS Server name and IP address will be displayed. Type "set type=mx" - This will cause NSLOOKUP to only return what are known as MX (Mail eXchange) records from the DNS servers. Type "hotmail.com" or your domain name.

How To Update MX Records Log in to your Control Panel. Go to Domain Central. Click on the domain you want to edit. Click DNS. From Modify, select MX Records. Enter the Priority: (the lower the number the higher the priority; i.e the system tries the server with priority 10 is before the server with priority 20)
