When you create a new mailbox, you may receive an error message saying you cannot use a domain. This error means that the domain does not meet the Acceptable Domains requirement and can’t be used.
It is important to understand what domains you can use and which you cannot. The error may also be referred to as a MigrationPermanentException.
MigrationPermanentException: You can’t use the domain because it’s not an accepted domain
If you receive this error, it means that your mailbox has not been successfully migrated. This problem can happen because your organization doesn’t accept the domain you are trying to use. Fortunately, there are some simple fixes that can solve the problem.
You can manage the DNS records yourself. To do so, simply input the correct TXT record into your DNS provider (Network Solutions, GoDaddy, or other providers). This will confirm to Microsoft that you are the owner of the domain name. It can take a while for Microsoft to verify this change, so you should be patient.
There are some domains that are not acceptable. These are generally government sites. For example, the government domain is used by the federal government of the United States.
These sites contain reliable information and informational materials. They should be listed in the Acceptable Domains list. These domains are not appropriate for business websites.
Unacceptable domains you Cannot Use
There are several types of organizations and websites that use a specific domain. These types of sites tend to promote a particular product or service.
The information provided on these websites may not be misleading, but they do have a monetary incentive for doing so. Therefore, it is important to avoid using these domains on your website.
When you are creating a new domain name, you must first create a TXT record for it. This will allow your domain to be listed in the Allowed Domains page. To make sure that you are using a valid domain, check whether it’s listed in the list.
