6 Ways to Fix Emails Disappearing from iPhone [2022 Updated]

Apart from calls and messages, email is another popular way of communication. It is mainly used for formal purposes such as contacting your professor or supervisor, making an application, applying for a job, sharing a document, etc. As a result, it is vital to keep track of your email. If your emails disappear from iPhone, it can be very stressful and lead you to other real-life problems.

Recently many users reported that emails are disappearing from their iPhones. If you are one of them, keep reading the article. It can happen because of a lot of reasons. This blog post will try to find out why your emails are disappearing from iPhone and what you can do to fix this issue.

Part 1. Why Are My Emails Disappearing from Inbox?

Emails may disappear from iPhone for several reasons. Here are some of the possible reasons that can make your emails disappear:

  • Improper Mail Settings: Like any other smartphone device, iPhones also enable users to customize their mail settings. If the settings are not correctly done, you may end up losing the emails from the inbox.
  • POP3/IMAP Conflict: Typically, the email programs on the desktop utilize the POP3 protocol while the smartphones utilize the IMAP protocol. Sometimes these two protocols can conflict and cause emails to disappear from the device.
  • System Error: Another common reason behind the issue is system error on iPhone. Although iOS has one of the most sophisticated operating systems out there, it often crashes and causes other system issues. These issues can cause the disappearance of the email from your inbox.

Part 2. How to Fix Email Disappearing from iPhone

2.1 Change Mail Settings to Solve Conflict between POP3 and IMAP on iPhone

Before we begin discussing the solution, you need to know about the POP3 and IMAP protocols. The POP3 stands for Post Office Protocol 3, which lets you download the copy of emails and view/use them locally. Besides, the IMAP protocol enables you to sync the emails on all your devices. Your iPhone utilizes the IMAP protocol, and if you somehow change it to the POP3, the email may start disappearing.

Below, we will show you how to customize Outlook 2016 that might help you solve the problem.

Step 1: Launch Outlook 2016 on your PC, go to File, and then Info. Find “Account Settings” from there and click on “Account Settings…”.

2.2 Force Restart iPhone

As we mentioned earlier, the error can also occur because of system crashing error on iPhone. The quick and easy way to fix such issues is by restarting or rebooting the phone. Don't know how to do this? Don't worry; the process is pretty simple. Here is what you need to do:

  • If you are facing the problem in iPhone 6 or older devices: Tap and hold the sleep/wake (power button) and home button for around 10 seconds. After holding the buttons for 10 seconds, the screen should go black, and the phone should restart. You can stop holding the button once the Apple logo occurs on the screen.

  • If you are using iPhone 7/7 Plus: Tap and hold the Sleep/Wake button along with the volume down buttons for 10 seconds. Like earlier, the display will go black, and the phone will restart. Simply let go of the buttons once the Apple logo occurs.

  • If you are using the latest iPhone devices: If you are using iPhone X to the other latest versions, you will need to go through a bit different method. First, tap the volume up button and release it quickly. Then, do the same for the other volume button. Now press and hold the side button until the apple logo occurs.
