Top 6 Ways to Fix “Failed to Verify Server Identity” Error on iPhone

The Mail app isn’t Apple’s most feature-rich offering, but it gets the job done. However, there may be times when Mail app on iPhone prevents you from exchanging emails by throwing “Failed to verify server identity” error.

Unreliable network connection, misconfigured settings and application issues are just some of the reasons why the Mail application may interrupt you with such errors. If you are unable to identify the exact cause, follow the troubleshooting tips below to help you.

1. Use a secure network connection

The Mail app may not be able to verify the identity of the server because you are on a public (less secure) network. Several users on the forums managed to get rid of the error by switching to a private network or cellular data. So that’s the first thing you should try.

2. Correct Date and Time on iPhone

An incorrect date and time on your iPhone can also hinder the connection between the Mail app and the server. Therefore, the application may prevent you from exchanging emails. Instead of setting the date or time manually, you can set iPhone to use the date and time provided by the network. Here’s how.

Step 1: Launch the Settings app on your iPhone and go to General.

2nd step: Tap Date & time and toggle the switch next to Set automatically.

3. Delete and add an account

If you only encounter this error on a particular email account, you can remove that account and add it back. This way, you can set up your account from scratch and fix misconfigured settings. Here’s how.

Step 1: Launch the Settings app on your iPhone and scroll down to tap Mail.

2nd step: Go to Accounts and select the email account you’re having trouble with.

Step 3: Tap the Delete Account option. Select Delete Account when a prompt appears.

After that, go back to the Accounts page and select Add account to sign in with your account.

Try using the Mail app to see if it works properly.

4. Disable SSL Encryption

SSL encryption (or Secure Socket Layer) is responsible for encrypting the connection between the Mail application and the server. If there is a discrepancy between the SSL certificates on your phone and the one on the server, you may encounter a “Failed to verify the identity of the server” error on your iPhone. You can try temporarily disabling SSL encryption to see if that eliminates the said error. Here’s how.

A word of warning. Disabling SSL makes your emails vulnerable to attacks. Anyone on the same network as you could potentially intercept the messages and view your user name and password in clear text.

Step 1: Launch the Settings app on your iPhone and scroll down to tap Mail.

2nd step: Go to Accounts and select the problematic email account.

Step 3: Tap your email id at the top.

Step 4: Go to Advanced and disable the Use SSL option.

If this method works, make sure to enable the “Use SSL” option after some time.

5. Reset Network Settings

Network-related issues can also prevent the Mail app from communicating with the server and lead to such anomalies. To fix this problem, you can consider resetting network settings on your iPhone by following the steps below.

Step 1: Open Settings on your iPhone, go to General and tap Transfer or Reset iPhone.

2nd step: Tap the Reset option at the bottom and choose Reset Network Settings from the menu that appears.

Enter your lock screen password to verify your identity and begin the restore process. After resetting the network settings, reopen the Mail app to see if the error is resolved.

6. Install software updates
