      4. Install the latest iOS version for your iPhone<\/h3>\n\n\n\n

      Another update you shouldn\u2019t miss is the iOS update. This update usually embeds critical patches to eliminate iOS bugs that caused issues to system services on different iOS devices. If you haven\u2019t set your iPhone to auto-update, then you can manually check and update through settings. Just make sure it\u2019s connected to the internet and has at least 50 percent of battery life to proceed. Just follow these steps:<\/p>\n\n\n\n

      1. From the Home screen, tap\u00a0Settings<\/li>
      2. Select\u00a0General<\/li>

        3. Scroll down and select\u00a0Transfer or Reset iPhone<\/p>\n\n\n\n

        \"\"<\/figure><\/div>\n\n\n\n

        4. Tap on\u00a0Reset<\/p>\n\n\n\n

        \"\"<\/figure><\/div>\n\n\n\n

        5. Select Reset All Settings<\/p>\n\n\n\n

        \"\"<\/figure><\/div>\n\n\n\n

        Your phone will restart on its own and then load up the default values and options. To use necessary features, particularly those that are disabled by default, you will need to re-enable them manually first.<\/p>\n\n\n\n

        6. Factory reset your iPhone<\/h3>\n\n\n\n

        A factory reset is the last resort if your Mail app still doesn\u2019t work and prompts a \u201ccannot verify server identity\u201d error. This reset will wipe everything from your device including saved data on the internal memory and then restores factory default settings. Remember to back up your phone and most used apps to avoid losing important information. Once you have secured your backups, follow these steps to factory reset your iPhone through settings:<\/p>\n\n\n\n

        From the Home screen, tap\u00a0Settings<\/p>\n\n\n\n

        1. Select\u00a0General<\/li><\/ol>\n\n\n\n

          2. Scroll down and tap on\u00a0Reset<\/p>\n\n\n\n

          3. Select the option to\u00a0Erase all content and settings. This will erase everything from your iPhone system including downloaded apps, customizations, and files stored on the internal memory<\/p>\n\n\n\n

          \"\"<\/figure><\/div>\n\n\n\n

          4. Enter your device passcode if prompted to continue<\/p>\n\n\n\n

          5. Then tap the option to confirm that you want to erase your iPhone<\/p>\n\n\n\n

          After the reset, you can use the startup wizard to set up necessary features including your email account in Mail using automatic settings.<\/p>\n\n\n\n

          7. Contact Apple Support<\/h3>\n\n\n\n

          If you tried all of the above methods and none worked, there may be some server issues with Mail. Consider contacting Apple Support and informing them of the issue and all the measures taken. In the meantime, you can download and use other third-party email clients like Gmail and Outlook.<\/p>\n\n\n\n
