Try Basic Fixes
- Use a secure network connection: The Mail app may fail to verify the server identity if you’re on a public (less secure) network. If that’s the case, switching to a private network or cellular data should help.
- Install software updates: You may see the “Cannot Verify Server Identity” error on your iPhone or iPad due to a bug within the Mail app or iOS. So, installing pending iOS updates will help. That will also update the Mail app on your iPhone or iPad.
Fix 1: Enable Automatic Date and Time
Incorrect date and time on your iPhone or iPad can also hinder the connection between the Mail app and server. As a result, the app may prevent you from exchanging emails.
Instead of correcting the date or time manually, configure your device to use the network-provided date and time.
Step 1: Open the Settings app and navigate to General.
Step 2: Tap Date & Time and toggle on Set Automatically.
Fix 2: Delete and Re-Add Account
Another option is to remove your account from the Mail app and add it back. This will allow you to set up your account from scratch and fix misconfigured settings.
Step 1: Launch the Settings app and scroll down to tap Mail.
Step 2: Go to Accounts > select the email account you’re facing issues with.
Step 3: Tap on Delete Account. Select Delete Account when a prompt appears. Then, return to the Accounts page and select Add Account to log in with your account.
Fix 3: Disable SSL Encryption
SSL (or Secure Socket Layer) encryption encrypts the connection between the Mail app and server. If there’s a discrepancy between the SSL certificates on your phone and one on the server, you may face a “Cannot Verify Server Identity” error on your iPhone or iPad.
You can try disabling SSL encryption momentarily to see if that eliminates the error.
Step 1: Launch the Settings app > go to Mail > Accounts.
Step 2: Select the problematic email account and tap on your email ID at the top.
Step 3: Go to Advanced > toggle off Use SSL.
Fix 4: Update Carrier Settings
Network carriers also update their settings to improve cellular connectivity on your device. You can try installing these updates to see if that resolves the error.
Step 1: Open the Settings app > tap on General.
Step 2: Tap on About. A pop-up should appear if there are any pending updates. Tap Update to proceed.
Fix 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, consider resetting the network settings on your iPhone or iPad by following the steps below.
Step 1: Open the Settings app > navigate to General > tap on Transfer or Reset iPhone.
Step 2: Tap on Reset at the bottom > choose Reset Network Settings.
Enter your lock screen password to verify your identity and begin the restoration process. After resetting the network settings, reopen the Mail app to see if the error is resolved.
