- Step 2: The error 400 on Zoho mail is a common error encountered by many users. Usually, this error occurs when the Zoho mail server is down or your request to the server fails. However, you can resolve this error easily.
- Step 3: Before performing the advanced troubleshooting steps, check whether your PC or smartphone is connected to the internet. To check it, try to open a random web page on your browser. If the requested page opens successfully, then your internet connection is stable. If not, your network connection might be the reason. Try to connect your smartphone or PC to the internet and check if this error code is resolved. If not, then the problem is with the Zoho Mail Server.
- Step 4: It is very common for an email server/service to encounter an issue. If the Zoho Mail services are done, the error code 400 is displayed on the screen. In this case, try to access your Zoho email account after a while.
