iPhone Mail: deleted Inbox messages keep reappearing

Hi acypher,

Since this only occurs on your iPhone, not on Mac or webmail, there may be an issue with this account on your iPhone. First, it may be helpful to use Mail - Official Apple Support to look up the settings for your email account. Then, go to Settings > Mail > Accounts > [Account name] to make sure they match what shows up using the mail settings lookup from the above link.

If everything looks OK there, try removing the email account using this guidance from If you can't receive email on your iPhone, iPad, or iPod touch - Apple Support.

"Remove your email account and set it up again

1. On your computer, sign in to your email provider’s website. Make sure that all of your email is there or make sure that your email is saved somewhere other than your device.
2. On your device, go to Settings > Mail, then tap Accounts.
3. Tap the email account that you want to remove.
4. Tap Delete Account.
5. Add your account again."

All the best.

Hey acypher,

We'll be happy to help! Have you tried switching networks and then attempt to delete again? This can rule out the issue being with the connection. For example, if you're connected to cellular data, try switching off cellular data and connecting to Wi-Fi only, or vice versa. If you're not sure how to turn off cellular data to connect to Wi-Fi only, follow these steps: Use cellular data on your iPhone or iPad - Apple Support

My phone, iPad and Mac Air keep returning large numbers of deleted mail. This is a nuisance as it means I must delete each item underneath and there are often hundreds.
