How to Set Up Business and Enterprise Email in Outlook 365
When you want to configure Business or Enterprise Email in Outlook 365. This article explains how to set up Business and Enterprise Email in Outlook 365.
Locating the Email Client Configuration settings
Before you can start configuring your Email Account, you will first need to understand and find the settings needed for the configuration as follows.
Non-SSL Hostnames
If you are configuring your Email Client using your branded hostnames, you will not be able to use the SSL ports. In this case, you can use the following hostnames.
| Outbound Server SMTP | smtp.domainname.com | port 25/587 |
|---|---|---|
| Inbound Server IMAP | imap.domainname.com | Port 143 |
| Inbound Server POP | pop.domainname.com | Port 110 |
The domainname.com in the above example needs to be replaced with your domain name. For example, if your domain name is example.com, the above-mentioned hostnames will be as follows.
smtp.example.com
imap.example.com
pop.example.com
SSL Hostnames
Our Email infrastructure supports TLS/SSL configurations on an Email Client too. We support STARTTLS on SMTP and SSL on IMAP and POP. Based on the product you have with us, you can use one of the following configurations.
Free Email or Business Email
Our Free Email and Business Email infrastructure is set up in two data centers. Depending upon where your order is provisioned, you will need to use one of the following hostnames.
Configuration 1:
| Outbound Server SMTP (STARTTLS) | imap.mailhostbox.com | Port 25/587 |
| Inbound Server IMAP (SSL) | imap.mailhostbox.com | Port 993 |
| Inbound Server POP (SSL) | pop.mailhostbox.com | Port 995 |
Configuration 2:
| Outbound Server SMTP (STARTTLS) | us2.smtp.mailhostbox.com | Port 25/587 |
| Inbound Server IMAP (SSL) | us2.imap.mailhostbox.com | Port 993 |
| Inbound Server POP (SSL) | us2.pop.mailhostbox.com | Port 995 |
Note
1. By default, all new orders are required to use Configuration 2. However, if you have old orders, you may need to use Configuration 1.
2. If you want to know for sure which configuration you need to use, you can simply go to your Email Admin Dashboard and go to Mail >> DNS Configuration.
You will find your configuration under the heading Branding Configuration.
