The stock Mails app of iOS allows you to connect with multiple mail servers such as iCloud, Outlook, Google, and more. The popup also includes the Cancel button, Details, and Continue. With the lower iOS 10, when you tap on the Details button, you can trust the certificate and continue with your day.
However, if your device is running iOS 10 and higher, it’s harder to fix the Server Identity verification issue on the Mails app.
Emails on iOS Showing Server Identity Error
To fix this problem in the Mails app, you follow these steps:
- Remove the email causing the issue by going to Settings > Mails and then tap on the Accounts Now, select the email you want to delete, and tap the ‘Delete Account’ option at the bottom.
- Hard Reset your iPhone by holding down both the Power and Home button (on iPhone 7/7 Plus is Power + Volume Down buttons) for a few seconds until the Apple logo appears on the screen. Wait for the device to boot up.
- Go to Settings > Mails and then tap the ‘Accounts’ tab again, tap on ‘Add Account’ and then add your old email address you deleted earlier.
- Power off the device by pressing down the Power button and then turn it back on
- Use the email’s dedicated app. For instance, if it’s a Gmail account, then you need to download the Gmail app from the App Store
- Delete the server from your Outgoing Mail Server in Settings. Once you read the email, it will show a popup window to “Verify Server”.
- Update to the latest Apple firmware by going to Settings > General > Software Update.

Many of people said that they got the “Cannot Verify Server Identity” error in their Safari instead of the Mails app. Both of these issues are similar, and here is how to fix them.
- Tap ‘Cancel’ on the prompt then go to Settings > Safari.
- Scroll down to the bottom and tap on ‘Clear History and Website Data’ and then confirm your action in the next prompt.
- Restart your iPhone/ iPad.
And the next time you visit the same web page again, it will not show the server verification error.
