Solution 4. Change mail settings to resolve POP3 and IMAP conflict

There are multiple ways you can access email - logging into your account through a web browser on your computer, using an app on your smartphone, using a desktop app like Outlook. Depending on how you access your email, you're either downloading a copy of the email to your device and using it locally using a protocol called POP3 (Post Office Protocol 3), or you're keeping it in sync with all of your devices using a protocol called IMAP (Internet Message Access Protocol). Normally, we would use IMAP on iPhone, which simply makes a copy without removing anything from the server. However, if you change IMAP to POP3 on iPhone somehow, there may be conflicts when you are using email app on mobile and desktop downloads as well. Eventually, that may lead to email disappearing error on iPhone.

In order to fix the issue, you can check the settings on your account. Take Outlook mail as an example:

1. On your mailbox, click on the "Gear" icon.

2. Select "More mail settings".

3. Under "Managing your account", select "POP and deleting downloaded messages".

4. Make sure that "Don't let another program delete messages from Outlook" option is selected.

After all the settings, click "Save" button. Then you can get back all mails from your iPhone inbox.
