When I'm trying to delete an email out of the Mail app it looks like it is deleting, but then doesn't delete

Fixed for me with 13.2, so far...

After you update to iOS 13.2.3 did you reboot your iPhone? If you didn't do so.

This link explains Force Restart if you don't know how --> Force restart iPhone - Apple Support

Fixed for me on iOS 13.2.3 (finally).

This is fixed for me. It may be iOS 13.2.3.

I think i started a live chat had to follow all the steps they told me to first.

delete mail app re instal mail app

erase iPhone and set up as new etc

just state that you wish to open a case because the mail app doesn’t function correctly. Emails don’t load fast enough on opening of the app, have to open emails twice for new email notifications to clear, have to delete mail twice and emails also appear to be sent twice. Also give them a link to this support page for ref and tell them you want a case number.

Apple has been working on this issue for over 3 weeks. There is currently no resolution. I encourage everyone to contact Apple Enterprise support to report and ask them to make a public statement or posting. ‭(866) 752-7753‬

Use this link to open a case regarding issues https://getsupport.apple.com/?caller=psp&PRKEYS=PL133

click on apps and features then mail questions or trouble shooting.

don’t just report as feedback, need to actually open a case.

thank you

Opened a case as per MARK2620’s suggestion. Asked me to restart me phone which I did. We did a screen connect, and one or two emails later, Mail app was behaving properly. However, I told him this case is far from being closed as I want to see correct behavior for several days across multiple devices with all 3 of my Exchange accounts. Mail had worked perfectly for me since iOS 8 to 12, but not 13. Will report back with what I see happening over the next several days.

I haven't heard about that specifically, if it consistently happens. I'd suggest calling Apple Enterprise support and report, they can do log and screen captures to see if it's related to all these other Mail bugs, which I suspect it is. (866) 752-7753

Start at the top and read through the thread - several users have been working directly with Apple support at several levels and have stated they acknowledge the issue and Apple is working on it. They have given them screen shots, deep level diagnostics, etc. Some levels of support blame it on Microsoft, other levels of support acknowledge that that is is a bug Apple is trying to address. That’s the latest. Bottom line - IT IS AN ISSUE THAT NEEDS TO BE RESOLVED. And there is NOTHING we can do at this current rev level of 13.2.

2 months into iOS 13 and this email problem still persists. This issue makes the Apple mail client unusable. I've given up on it and downloaded the Outlook app instead.

So far so good. Bye bye, Apple mail.

For those that are still experiencing this issue, I highly recommend downloading and trying the Microsoft Outlook app.

It supports various mail accounts - Outlook, Gmail, Exchange, iCloud, etc.

It took me a day to adjust to the new mail client, but I'm loving the switch.

Same here. Turning on ‘organize by thread’ seems to have helped.

Updated my phone today and so far so good. 13.1.3

I first saw this on my Iphone 11 Pro. Then I upgraded a separate Iphone X from IOS 12.4.1 to IOS 13.1.2. With both phones on IOS 13.1.2 and Microsoft Exchange mail set on both. Only the Iphone 11 Pro requires it to be deleted twice. The Iphone X setup with the same mail account only requires 1 delete. I ran tests by sending 4 separate mails which were exactly the same, which went to both phones. First test deleted off Iphone 11 Pro, required 2 deletes. Next deleted off Iphone X, only 1 delete required. Repeated and same results.
