Reset Domain in Zoho Desk lets you remove or change the custom domain mapped to your Help Center (portal) so you can restore the default Zoho Desk subdomain or prepare the portal for a new domain. It handles the DNS and portal link changes that affect how customers reach your knowledge base and support pages.
What is it — 2-4 sentences answering "what does this feature do in Zoho Desk"
Reset Domain clears the custom domain mapping on your Zoho Desk Help Center and returns the portal URL to the default portalname.zohodesk.com/portal address. It removes the association between your purchased domain and the Desk portal, so DNS records and SSL provisioning tied to the old mapping stop routing traffic to your Help Center. After reset, you can either leave the default Zoho Desk link in place or reconfigure a different custom domain mapping. This operation is primarily administrative and affects public access and branding for customers who visit your portal [1][7].
When to use it
- You discontinued or lost control of a previously mapped domain and must remove its association from the Help Center to avoid access or security issues [4].
- You plan to move the Help Center to a new custom domain and need to clear the old mapping before adding the new DNS records [1].
- You want to revert temporarily to the default Zoho Desk subdomain while you test portal changes or SSL renewals on your custom domain [1].
- You are transferring ownership of the portal or reorganizing branding and must remove customer-facing links tied to the old domain [7].
- You must remove an incorrect mapping that was created during setup so you can reconfigure the correct domain and DNS entries [1].
How to access it
Open Zoho Desk as an administrator, go to Setup (gear icon) > Rebranding > Domain Mapping (or Help Center settings where custom domain is configured), select the mapped domain entry and choose Reset or Remove mapping to restore the default portal URL. If your organization manages domains centrally in Zoho Directory, check Domains under Directory to confirm domain verification or removal steps before or after resetting the mapping [1][7].
Related features
- Domain Mapping / Custom Domain setup for Help Center (to add a new custom domain after reset) [1].
- Zoho Directory > Domains (verify, add, or delete organization domains that affect Desk and other Zoho apps) [7].
- Portal Configuration in Zoho Projects or Zoho Recruit (other Zoho products with subdomain/custom domain mapping workflows) [3][6].
Notes
- Resetting the mapped domain stops the custom DNS routing and associated SSL certificate issuance for that mapping; customers will reach the portal via the Zoho Desk default URL until you map a new domain [1].
- If the domain you remove is also used across other Zoho services, confirm the domain state in Zoho Directory before deleting it to avoid disrupting access elsewhere [7][4].
