How To Fix the "Cannot Verify Server Identity" Error on iPhone X

If you're using your iPhone X to access your work email, you may come across a message that reads "Cannot Verify Server Identity." This error typically appears when your IT administrator has changed the authentication settings of your company's Exchange server. However, there are various other reasons why this message may pop up on your device.

For example, updating your iPhone X's software or switching network connections (such as from Wi-Fi to mobile data or vice versa) can trigger this error message. Even minor changes to your device's settings can result in this issue. Additionally, changing your Apple ID account password can also cause this error to appear on your phone.

This article will help you understand the common causes behind the "Cannot Verify Server Identity" error message and provide you with solutions to fix it on your iPhone X. By following the steps outlined in this article, you can easily troubleshoot the issue and get your work email back up and running on your device.

How to Fix the "Cannot Verify Server Identity" error on iPhone X

Change your password

One of the most common reasons why you may be seeing the "Cannot Verify Server Identity" error on your iPhone X is that the password used to authenticate your email account is incorrect. If your IT administrator has recently changed the password for your account, you may need to update the information on your iPhone X.

You can follow these steps to change your email account password: Open the Settings app > Mail >Select your email account > Enter your current email password > And change your password as required. Since every email account differs, these steps may vary slightly for each email service. If you’re unsure how to change your email password, you can contact your email provider or look into their Help section for instructions.

Restart Your iPhone X

Many issues can be fixed by simply restarting your device. If you’re having trouble authenticating your email account, try restarting your iPhone X. To do so, hold down the Sleep/Wake button for a few seconds until the red slider appears. Alternatively, press and hold the side and volume down buttons.

Turn Off Auto-Fetch for Exchange Email

If you're experiencing the "Cannot Verify Server Identity" error message on your iPhone X, it could be due to a server communication issue. One way to resolve this issue is by turning off the Auto-Fetch feature for your Exchange email. To do this, follow these simple steps:

Go to Settings > Mail > Accounts, select your email account, then select Advanced > Exchange > Auto Fetch > OFF > Save.

By disabling Auto-Fetch, you can prevent your phone from attempting to automatically fetch new emails, which can sometimes cause server communication issues. Once you've turned off this feature, you can try accessing your email account again to see if the error message has been resolved.

If this solution doesn't work, there may be other underlying issues that need to be addressed. In that case, it's recommended to reach out to your IT administrator or email service provider for further assistance. With these troubleshooting steps, you can quickly resolve the "Cannot Verify Server Identity" error and get back to using your iPhone X for work email.

Close the Mail app and launch it again

Sometimes, the apps can behave strangely and not work correctly. The Mail App is no exception. All you have to do is force close the Mail app and launch it again.

Reset all settings

The "Cannot Verify Server Identity" error may be caused by an outdated app or network configuration. In this case, resetting your iPhone X's settings will reset everything back to its default state. You may need to update your network settings or WiFi passwords.

  • Open Settings >> General >> Transfer or Reset >>Reset >> Reset All Settings
  • Enter your passcode
  • Tap Reset All Settings
  • Your device will restart.

Delete your email account and add it again

If none of the solutions above work, you may want to consider deleting your email account and starting the setup process again. Doing this will not erase your data; you will just remove it from your iPhone X. To delete your email account, follow these steps:

  • Open Settings and then go to Mail
  • Tap Accounts.

  • Select your email account
  • Tap on it and then tap Delete Account or Sign out
  • Tap Delete Account to confirm the action

Once you're done with this, go to Settings > Mail > Accounts> Add Account. Choose your email service and provide the information needed.

Use a VPN

Sometimes, using a Virtual Private Network (VPN) can help resolve server communication issues on your iPhone X. A VPN can help mask your device's IP address and provide a secure connection to your email server. There are several VPN apps available on the App Store, such as NordVPN or ExpressVPN, that you can use to establish a secure connection to your email server.

In conclusion, the "Cannot Verify Server Identity" error message on your iPhone X can be frustrating and can prevent you from accessing your work email. However, by following the steps outlined in this article, you can troubleshoot and fix this issue. Whether you need to turn off Auto-Fetch, restart your device, clear your cache, reset network settings, or use a VPN, there are several solutions available to help you resolve the error and get back to using your email account.

If you continue to experience issues with the "Cannot Verify Server Identity" error, it's recommended to reach out to your IT administrator or email service provider for further assistance. With these troubleshooting tips, you can quickly and easily resolve the issue on your iPhone X and ensure that you stay connected to your work email without any interruptions.
