Hello @Dharma Apparasu

For Custom Domain issues, please comment the below and follow up once, post that close it as Redirect support

Based on your description, it seems that you are unable to verify your custom domain in your Entra ID tenant, even after correctly adding the TXT records in your domain provider side.

This issue often occurs when the domain has already been verified in another Entra directory, as explained in the following document: Common verification issues

To resolve this, the recommended approach is to contact the Microsoft Data Protection team. You can reach them by calling Microsoft Customer Service using the phone numbers listed here: Customer service phone numbers - Microsoft Support.

Hi,

I have already added the required TXT record and verified that it has propagated correctly. However, I am still unable to verify the custom domain, and it appears that the domain may still be associated with a previous Entra tenant.

Could you please guide me on the next steps or help initiate the process to remove the domain association from the previous tenant? If any additional information is required from my side, I would be happy to provide it.

Thank you for your assistance.

Best regards, Kartik Jangid

Domain appicsolutions.com can only be verified in a single Microsoft Entra tenant at a time. Even if the TXT record is correct, verification in the new tenant fails while the domain is still present in another directory.

To resolve:

Confirm the TXT record is correct and visible
- Use an authoritative DNS lookup (for example, nslookup -q=TXT appicsolutions.com or an online DNS lookup tool) to ensure the verification TXT record exactly matches what the new tenant shows.
- If the TXT record is missing or incorrect, fix it and wait for DNS propagation, then retry verification.
Check whether the domain is already in use in another directory
- A custom domain can only be verified in one Microsoft Entra tenant at a time. If appicsolutions.com is still verified in another tenant (including an unmanaged/self-service tenant such as Power BI or a different Entra directory), it blocks verification in the new tenant.
- The blocking tenant might be:
  - A previous organization’s tenant that still has the domain attached, or
  - Another directory under the same subscription (for example, an Azure “Default Directory”) where the domain is added as Unverified or Verified.
Remove the domain from the old tenant
- Sign in to the Microsoft Entra admin center of the tenant that currently holds appicsolutions.com.
- Go to Entra ID → Domain names and locate appicsolutions.com.
- Delete the domain from that tenant. A domain must be removed there before it can be verified in a different tenant.
- If the domain is in an unmanaged tenant (for example, created by self-service Power BI sign-up), perform an admin takeover of that directory, then delete the domain. See the guidance for taking over an unmanaged directory.
Re-add and verify in the new tenant
- In the target tenant, go to Entra ID → Domain names → Add custom domain and add appicsolutions.com.
- Ensure the TXT record shown is present in DNS.
- Select Verify. Once the domain is no longer present in any other tenant and the TXT record is correct, verification should succeed.

If the domain was previously expired and re-registered, still ensure it is deleted from any old tenant where it was used. Microsoft will not allow the same domain to be verified in more than one Entra tenant.
