Hello, @IniobongNkanga-8038,
Welcome to the Microsoft Q&A platform!
Based on your description, you want to update your nameservers in Microsoft 365 but cannot see the option to change nameservers in your account. Here's a step-by-step guide to help you:
1.Log in to the Microsoft 365 Admin Center, navigate to "Settings," and then "Domains."
2.Select your domain and look for DNS management options.
3.Switch from Microsoft-managed DNS to custom DNS if necessary and update the nameservers with those provided by Wix.
For more details about how to finish this, please refer to https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/change-nameservers-at-any-domain-registrar?view=o365-worldwide#change-your-domains-nameserver-ns-records.
If you don't see the option to change nameservers, it might be due to specific settings or restrictions on your account. In that case, I recommend contacting Microsoft 365 support for further assistance by clicking "Support" or "Need help?" in the lower-right corner. Explain your situation, and they can provide specific guidance for your account and domain configuration. Ensure you have the nameserver details from Wix handy when updating.
Should you need more help on this, you can feel free to post back.
