13 Fixes for "Email Not Working After Updating to iOS 26"

After upgrading to iOS 26, some iPhone users report that their emails are not coming through after the iPhone update. Email suddenly not working is quite common among iOS update issues - some users might fail to receive new emails, while others have difficulty replying to emails.

• The update might have failed or been incomplete.
• The update might have reset some settings, such as filters or forwarding rules.

How to Get My iPhone Email Back to Normal on iOS 26?

Based on the possible reasons, we’ll introduce 10+ ways to resolve the email not working issue.

Restart the Mail App

The easiest thing to do is to restart the Mail application. By closing and reopening the Mail application, you can resolve email client issues.

Check Internet Connection

It’s essential to maintain a stable internet connection when sending or receiving emails. If your iPhone is not connected to Wi-Fi or cellular data, or if the connection is weak, you won’t sync, send, or receive new emails.

To get a more stable network connection, you can switch between Wi-Fi and cellular data. Open some online videos to see whether the internet is stable.

Update the Mail App

Make sure to always update your Mail app, as this can help prevent compatibility issues between the email client and the server.

Go to the App Store and check if an update for the latest iOS 26 is available.

Reinstall the Mail App

Whether or not there is an update, you can reinstall the Mail app. By deleting and reinstalling the app, you reset it to its default state and refresh the configuration and settings.

Check Email Account Settings

This works when you encounter issues such as emails not syncing, getting new emails with latency, or failing to send emails. Sometimes, incorrect or outdated settings can stop you from sending or receiving emails. After updating to a new iOS version, server addresses, port numbers, or authentication types can be changed, disrupting email service.

By verifying that the in (IMAP/POP) and out (SMTP) server settings are correct, you can ensure that your iPhone can communicate properly with your email provider's servers. Meanwhile, you can verify settings like username, password, and security settings.

To verify the settings of your email account, you can:

1. Open the Settings on your iPhone.
2. Go to “Accounts & Passwords” and click on your email account and “Advanced”.
3. Ensure that the incoming (IMAP/POP) and outgoing (SMTP) server settings are correct.

Check Junk Folders

For whatever reason, your emails might be sent to the Spam or Junk mail folders. Email providers use algorithms to filter out unwanted or malicious emails, but the systems are not perfect and sometimes mark good emails as junk or spam. By checking into these directories, you can ensure that important emails have not been incorrectly marked and ignored.

To check Spam or Junk folders, simply open the specific folders and find out whether your emails are there. Besides, you can adjust the Spam filters in Settings:

1. Open Settings and navigate to “Accounts & Passwords”.
2. Click on your email, find Mail, and adjust the Junk filter settings.

Account Syncing

The syncing settings might become disrupted after a recent update. To ensure your email account is well-connected with your device, you should also check the syncing settings. By verifying the syncing status, you’ll see whether your iPhone can regularly check and download new messages.

To check the Sync settings:

1. Launch Settings and navigate to “Accounts & Passwords”, your email account, and Mail.
2. Ensure your account is set to sync.
3. To force sync, fetch new data, and enable the “Push” option.

Check Blocked Senders

Similarly, you can check the blocked senders list:

1. Open Settings and tap on “Accounts & Passwords” and your email account.
2. Click on Mail and check out the blocked senders list.
3. Remove the senders that shouldn’t be blocked.

Check Storage Limits

If your inbox is overloaded or there isn’t sufficient storage space on your device, you won’t receive emails. If your inbox is full, you cannot receive new emails. Likewise, if your iPhone doesn't have much free storage space, it might have trouble downloading and reading new emails.

Check the inbox storage and ensure it is not full. You can delete redundant emails to free up space.

Similarly, you can check the storage space on your iPhone. Always ensure your device has enough storage space.

1. Open Settings and go to General and iPhone Storage.
2. Delete unwanted files to get more storage space.

Check Update Errors

When the update files are not installed correctly, the Mail app might not work as usual. In this case, you’d better check whether the update is successful. With a complete iOS update, all components of the Mail app can be compatible with the current system.

You can check the update in Settings:

1. Open Settings and click on “General” and “Software Update”.
2. Check if you’re running the latest iOS version.

Besides, you can force restart your iPhone to resolve incomplete update issues.

Check Third-Party App Settings

Certain third-party email apps might affect how you send or receive emails on the new iOS platform. You need to configure settings, such as server addresses, port numbers, etc. To ensure the email works well with the current iOS version, you should update your third-party email app.

To check whether the app can work well on your current iOS system, go to the App Store and check for updates. Also, you can reload your account in the third-party email app to get proper configuration.

Reset All Settings

This will reset all settings on your iPhone, including Mail settings. It’s noted that this won’t cause any data loss or app loss. It will only reset settings.

1. Navigate to Settings, General, and Reset.
2. Click on “Reset All Settings”.

After resetting all settings, you can re-add your email account to your device.

1. Go to Settings.
2. Click on “Accounts & Passwords” to add an account.

Downgrade Your iOS System

If you fail to fix the email issues with the above method, downgrade the iOS version to a previous one. Sometimes, new iOS updates, especially the beta version, may involve bugs or compatibility problems. If it’s a faulty version, revert to a more stable one.

To safely and efficiently downgrade the iOS system, you can use BuhoRepair. It simplifies the process of downgrading, making sure the email apps work in the stable system.

Here's how:

1. Free download BuhoRepair on your Windows or Mac computer and connect your iPhone to the computer.

   

2. Choose “Upgrade/Downgrade iOS” and select “Downgrade Version”.

   

3. Select the iOS version you’d like to downgrade to and initiate the process.
