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

Update, 13.1.1 did resolve the issue. Tested with a few more emails after my post above.

I think I may have found a solution to this. First of all I'm using an iPhone 8 with 13.2, and have had this exact issue since upgrading from IOS 12. I'm using 4 Exchange type accounts, 2 are on premise Exchange servers and 2 are Office 365s. All exhibited the same issue. I'm not sure if this will work for POP/IMAP accounts, as I don't use those.

This works for me since the initial IOS 13 update.

* I think this is the main setting that matters. The rest should be personal preferences, but I thought I'd share all the settings I use.

Try going in to your outlook or office 365 account and removing all mobile devices. Do this by opening outlook online then settings >all settings >General > mobile devices. Then remove the account from your phone through the passwords and accounts. Finally, add the account back.

This seemed to work for me so far.

This glitch is so bizarre. So 13.2.3 seems to have fixed the double delete problem. However if you are scrolling through new messages by opening a new message and hitting the down arrow in the top right corner to get to the next message it still shows every new message twice.

As you are replying direct to me, all I can say is the subject of this thread (tap twice to delete) was fixed in 13.2.3 and the duplicate sent items fixed in 13.3 thanks mainly to "all of us complaining" as you describe it.

If you have an unwanted email delete problem you could start a new thread.

Based on release notes, this is supposed to be fixed in today’s release of 13.2.3 here’s hoping.

Just downloaded iOS 13.1.1 and it seems to have fixed the Exchange message double-delete issue for me.

I couldn't find official Apple link that describes all the fixes but this link doesn't mention any fix for Apple Mail

I'm just amazed that Apple has released two updates already to iOS 13 in less than a week. How many bugs are there? When is the next update coming? Sheeesh.

Try going in to your outlook or office 365 account and removing all mobile devices. Do this by opening outlook online from a computer web browser then go to settings >all settings >General > mobile devices. Then remove the account from your iPhone through the passwords and accounts. Finally, add the account back.

The process is the same for personal accounts. Go to settings, then open all outlook settings. In the general section under mobile devices, you will see a device list. Remove all devices, then remove the account from your phone and add it back.

This problem came with one of the recent iOS updates a few months ago. I now open the mail list and drag the message to delete to the left and select trash from the more, flag or trash boxes. This works for me. If I delete from the open mail message, I must delete the second time.

13.1.2 solved my problems.

• delete mails need to klick only once
• sent mails are visible only once

but, how can these issues need 3 updates to be resolved?

It has worked for me since I turned on organize by thread in mail settings.

The only solution right now is to not use the Apple Mail App. The Microsoft Outlook app seems to not be affected

Try this. From the email click the Reply arrow, and select Delete from that menu. Then retry using just the delete icon. This seemed to clear the bug for me
