Manage domain

(Does not apply to the Free plan. Only available for the plan that users register with a domain.)

Add subdomains or delete added subdomains.

You can use both the new and the existing domain by using a subdomain feature.

By adding a subdomain, all members will have a new email address that includes ‘member ID@subdomain’and the existing email.

In the ‘Sender’ section for the email, you can enter the email address with the default domain and subdomain.

Emails received to the subdomain email address are also sent to the inbox of the default domain. An email sent to the subdomain address has a subdomain mark in the title for distinction in the default domain mail inbox.

Add subdomain

Add subdomains in addition to the domain you used to sign up for LINE WORKS.

You can add up to 10 subdomains.

To use LINE WORKS mail as a subdomain, set the MX record in the DNS of the subdomain (if you do not use LINE WORKS mail, you can also use the TXT/CNAME setting). After the new MX record setting is confirmed by LINE WORKS, you can have both the default domain and the subdomain email address as the sender’s email address.

  1. Select ‘Settings’ from the left to expand the menu and press ‘Domain’ to access the page. On mobile, tap the button to access the menus. On mobile, tap the button to access the menus. 
  2. At the top right, press ‘Add domain’.
    • When the default domain status is ‘In use’, ‘Add domain’ is displayed.
  3. Enter the subdomain and press ‘Complete’.
    • You cannot set domains already in use within LINE WORKS or subdomains as subdomains.
  4. Activate subdomains with MX record settings.
    • If you do not use LINE WORKS mail, you can also set TXT/CNAME.

Depending on the domain hosting website, the confirmation of the connection setting on the MX record may take up to 72 hours.

When the subdomain is ‘In use’, a new subdomain email address is available for all members. Emails can be sent or received with the new subdomain email address.

The added subdomain will be deleted automatically if not activated within 14 days.

 

Delete subdomain

Delete the added subdomains.

  1. Select ‘Settings’ from the left to expand the menu and press ‘Domain’ to access the page. On mobile, tap the button to access the menus. 
  2. Press ‘Delete’ to delete the domain you want to delete in the list.

When you delete a subdomain, all members’ subdomain email addresses are deleted immediately. You cannot receive or send an email with the deleted subdomain email address.

You cannot delete the default domain.

Select between default domain and subdomain

The Supreme admin can change the subdomain that has domain ownership verified to the default domain.

To change the default domain, you must add as a subdomain in advance.

The following are precautions of changing domains.

  • Domain change may take longer when your company has many members.
  • Once the domain has been changed, you cannot change it again within 24 hours. Also, every member will be instantly signed out and required to sign in using the ID with the new domain.
  • Add personal emails of every member to notify information changes conveniently. The information change will be sent to personal emails automatically.
  • Once the domain is changed successfully, an email and SMS are sent accordingly to the Supreme admin’s personal email and registered phone number.
  1. Select ‘Settings’ from the left to expand the menu and press ‘Domain’ to access the page. On mobile, tap the button to access the menus. 
  2. Press ‘Change to default domain’ on the right of ‘In use’ status of the subdomain.
    • To set ‘In Use’, set the MX record on the subdomain to verify the domain ownership.
  3. Press ‘Change domain’ after checking precautions.
