You will need to go to https://identity.accessacloud.com/manage/domains.
Within this page you will need to:
Press Add Domain.
Add the Domain Name ending of the company email address (e.g @theaccessgroup.com)
Save Changes.
Create a Notepad on your PC or a Txt file with the below lines:
Host: @
Type: TXT
Value: The entire verification code from the Domains page
Send this to your IT team to add this to your DNS Record and Email Domain Control
Once it has been added to the DNS Record, the domain should appear in the Verified Domain list.
If verification is unsuccessful, confirm the TXT record has been added to your domain DNS correctly and that this change has fully propagated before attempting verification again.
If verification is successful, you have now confirmed ownership of your email domain and are now able to create a Security Policy to apply to your users.
