Emails often not sending and not found in Drafts or Outbox (simply disappear).

Hello mshaughn,

Since it's occurring with multiple accounts, the easiest option is to remove the accounts, and then restart your device.

Once restarted, you will re-add the accounts, and see if that corrects the issues.

Make sure your email accounts and emails are on some other device, just in case you have issues. Also, you want to ensure you have a backup before any major system changes: How to back up your iPhone, iPad, and iPod touch

The reason to ensure the emails are on another device is in the case that one of your accounts is a POP email account, meaning the emails aren't saved on the server, so they would not redownload to this device once you set them up again. If that's the case, you can forward the most important emails from your other device.

If that's not something you are worried about, or you know all your accounts are IMAP accounts, then go ahead. You can look up each account settings here just to be sure: Mail Settings Apple

When ready:

1. Remove all the accounts with issues: Add and remove email accounts on iPhone - Apple Support
2. Restart your iPhone - Apple Support
3. Re-add your accounts one-by one.
4. Test.

Thanks.

Hello mshaughn,

The key to finding a solution to an issue like this is to isolate where the issue is occurring.

With that in mind, since you have multiple email accounts, you will want to definitely determine if this is happening with one or multiple accounts.

If it is only with the one account, then we would suggest you work with your University's Alumni IT team to troubleshoot what is happening.

Also, if you have any other devices with that account on it, test from there and see if the issue occurs. This would also point towards an issue with the account, rather than the iPhone.

If it is happening with multiple accounts, then we should suggest turning your focus to the iPhone itself.

Have a good day.
