Part 2. 8 Solutions for iPhone Mail: Connection to Server Failed Issue

The main problem we are looking right is connectivity. Your phone is unable to sync the email to its servers. Meaning, there are blockages in between.

It could be the internet, the email provider or a maybe a software bug. However, most bugs get fixed by updating the software and it is sent over-the-air (OTA).

Solution 1. Re-Enter Email Password & Account

Did you recently change your email password from the browser? If yes, then most probably this is the main reason why you get this mail connection to server failed error.

What you can do is update the password on the iPhone so there will be no more issues with syncing your emails.

  1. On your iPhone, head over to Settings
  2. Tap Accounts & Passwords
  3. Select the exact email account and then tap ‘Delete Account’
  4. After deleting, head back to ‘Accounts & Passwords’ and add the account again

Solution 2. Move Email to a Different Inbox

Another possible solution to this server connection issue is by moving the inbox to another folder temporarily. Here are the steps:

  • Highlight all the emails in the inbox or select those emails you wish to open
  • Tap “Move” and transfer it to a new folder
  • Open the new folder to access the emails

Solution 3. Change or Update Microsoft Exchange Security Settings

If you are using Microsoft Exchange email and you got this connection to server error, it may be due to invalid permissions.

You may contact your IT dept. or Email Administrator to get this straightened out. They will be the one to change or update your Microsoft Exchange security settings.

Solution 4. Change the ‘Mail Days to Sync’

In order to save space on your iPhone, you can actually manage and tell the server to limit sending all the emails on your phone. This is what you can do with the ‘Mail Days to Sync’.

So, to get all the emails, you can switch this setting to ‘No Limit’. Here’s how:

  1. Open Settings on your phone
  2. Go to Mail, Contacts, Calendars
  3. Choose the Exchange email account
  4. Scroll and find ‘Mail Days to Sync’ and select ‘No Limit’

By choosing ‘No Limit’, you are now able to receive all the emails in the inbox and other folders on the iPhone.

Solution 5. Check Internet Connection

Most of the time, the error is caused by poor Wi-Fi signal or mobile data. First, check your signal strength before accessing your emails for fast and hassle-free connection.

Solution 6. Restart the iPhone

Perhaps, a good restart is what your phone needs right now, simply turn off the iPhone and give it at least 20 seconds and turn it back on.

Most issues are actually resolved by a quick restart.

Solution 7. Reset Network Settings

Finally, if the above all solutions fail, the next option to do is to reset your network settings. Resetting the network settings will affect Wi-Fi, VPN, Bluetooth, and cellular connections, so you might need to set up these features again.

To reset your network settings, follow these steps:

  1. Launch Settings and go to General
  2. Tap Reset and then tap Reset Network Settings
  3. You will need to enter your passcode
  4. Select Reset Network Settings and restart the iPhone

After resetting the network settings, you need to re-enter and reconnect to your Wi-Fi network and fill in the passwords again. You also need to configure other cellular settings. Resetting your network settings does not erase any of your media contents like photos and videos.

Solution 8. Factory Reset The iPhone

Let’s say resetting the network did not resolve the iPhone mail connection to server failed issue. The last option you can do is to perform a factory reset. At this point, you will lose your phone data.

If you have created an iTunes or iCloud backup, then you can proceed, otherwise, you need to create a backup first.

Here’s how to factory reset your iPhone:

  1. From Settings go to General.
  2. Select Reset and tap Erase All Content and Settings
  3. Choose Erase iPhone
  4. Enter your phone’s passcode
  5. You will also need to enter the Apple ID to confirm the request
  6. Wait until the device completes the reset.

After the phone has finally reset, you will be able to restore your backup from iTunes or iCloud.
