Message not downloaded from server

Hi mrsd803,

The support article If you can't receive email on your iPhone, iPad, or iPod touch outlines steps to take for problems receiving emails:

"Before you begin

There are a few things to keep in mind and check:

• When you make an iOS or iPadOS backup in iCloud or iTunes, it backs up your mail settings, but not your email. If you delete or change your email account settings, previously downloaded emails might be removed from your device.
• Make sure that your device is connected to the Internet.
• Check with your email service provider to find out if there's a service outage.
• If you can't access your email, or you can't send and receive messages with your @icloud.com email address, learn what to do."

As it's only impacting some emails, look for commonalities between the messages. Are they from the same sender? Same company? What kind of content is expected, and can you view those messages on your email providers website? Isolating the relevant factors will help determine the best way to proceed.

Regards.
