IOS13 Mail outlook.com duplicate sent items

I have 2 accounts-one exchange and one outlook365 and the problem is on both. Probably related bugs: ghost emails-deletes that come back, takes 2 efforts to delete an email, emails deleted on desktop don’t synchronized with iPhone, etc.

having this issue too with my (two) outlook accounts. No issue with gmail. Duplicate sent emails seem to be device-specific: will have duplicates on my iphone if sent from there, but duplicate doesn't appear on my iPad, iMac, etc.

Both iPhone and iPad updated to latest version of iOS 13. iMac too old now...

I have the same issue also. After spending nearly 8 hours on the phone with an Apple adviser using remote access and deleting and reinstalling my phones system as well as my hotmail accounts the problem still exists. The reason eventually given is that as hotmail is an older email program from Microsoft it was not considered when making appropriate changes in 13.1.1 and 13.1.2. The last advice given was that Apple are aware of the problem now and are working to resolve it. I’m expecting a callback from their very helpful consultant in a few days.

Happy greetings to your "very helpful consultant". Hotmail might or might not be an older email program (its not even a program but ok). But Exchange Online aka O365 is an industry standard. How 'bout dat?

First time I laughed about this issue! The problem was a with Apple Mail running Outlook 365 and exchange accounts and perhaps others (I only use those). Emails show up in the sent folder of both accounts twice. However if you open the “top” of the 2 emails in the sent folder the content all appears but then the duplicate disappears from the sent folder. I only use Apple Mail on my iPhone XR running 13.1.3 but this may be occurring on iPads etc. it does not occur using my windows PCs using Outlook desktop as the client. It also does not occur using Outlook mobile on my iPhone or Spark for email.

Also Apple Mail does not appear to synchronize correctly once i access email on my PC-the folders don’t synchronize correctly. For example messages deleted on my iPhone still show in the delete folder on my PC.

Further, emails on my iPhone Mail inbox show only once in the list, but hitting delete doesn’t always delete them and the immediately reappear as a new message. The second delete seems to resolve it.

Lastly in Text message using Apple Messenger we used to be able to click on contact to call send them a text. Now it just opens the phone app or a blank text with no addressee.

they really made a mess of their own products. Blaming Microsoft is not correct.

Interestingly spotted something with this on my device - iPhone SE with o365 exchange and iOS 13.

Initially there was a duplicate sent item - 1 just with the original text and 1 with the text and the server added signature.

When I selected them both to look further then the signature one disappeared.

I wonder if there is a server or 365 side signature manager such as Codetwo which is causing issues?

It won’t be helped by MS wanting you to use the Outlook app. Since this started I’ve been using it and once you get used to it, it’s very useable.

I had a need to ring O365 support in the summer and they wouldn’t help if I wasn’t using their Outlook.

Another user/company to add to the list having the same problem. I'd like to know for sure if one of the duplicate emails that we see in the "Sent" folder is stored locally on an iPhone/iPad and does not contribute to the overall storage quota for each user. In other words, is it taking up twice as much storage space on our Exchange Server? If 1 email is part of exchange and the other is stored locally, well, at least I don't have to worry about increasing storage! Geez. Hoping to see 13.1.4 with this specific fix.

Same here. I've switched to using Outlook app. I wasn't a fan of Spark but others like it. Using either of these two apps solves the various problems with IOS mail and O365/Exhange. And I agree - as a business tool the iphone is getting less and less practical. Email is a critical aspect of using this product. If it doesn't work properly ,then all the phone really good for is as a media consumption device. Perhaps that's the r e a l intent. Going back to a blackberry with a PKB seems an option once again :)

Updated to iOS 13.2 last evening. Nothing is fixed on the duplicates, either on the iPhone nor the iPad. After a hard re-boot, I was optimistic at first... the very first e-mail I sent through the Mail App only shows up in SENT folder once... but the 2nd one, and all afterwards, are duplicated still.

I am using only G-Suites as our back office - not Outlook nor Outlook.com! My personal e-mail, with incoming and outgoing servers being different, is not affected. Only the single server business e-mail account has Dup's. in the SENT folder.

Apple - this is an iOS issue that should have been resolved by now after 4 updates to iOS 13! Please review this issue and send us all an update that solves this issue so we can stop talking about it and wasting everyone's time. None of us experienced this issue prior to iOS 13.

My support agent called with a update from

engineering in regards to current mail app issues. He told me engineering have responded and have said they have tested everything and that iCloud email works fine therefor it’s not a issue with Apple or device.

told me to contact outlook support for further assistance

That is what I was told a while back, but still the situation is unresolved.

I am using, as I mentioned earlier, G-Suites, not Outlook or Outlook.com! I still have the duplicate e-mails in my SENT folder in the Apple Mail App. This has only occurred since I updated to iOS 13, never before that. This is definitely an iOS 13 issue - no question about it.

Apple... Please help!

This makes me do annoyed

Apple are passing the buck

outlook works fine on previous IOS it is definitely an IOS 13 problem

they did the same to me when my iMessages stopped working and blamed my carrier (EE)

surprise surprise it was an Apple problem

The Apple agent I spoke about this issue said it was a problem which Apple was aware of.

I am increasingly ****** off with the lies and lack of customer service

Infuriating. I expect more. It has been weeks, and so many of us have diminished productivity at work, and are frustrated. Are they really not planning on fixing this problem? If so, please tell us now and we can take our business elsewhere.

Just installed the final release of ios 13.2. The issue has not been fixed! I spoke to a support rep, who happened to tell me that he himself used an MS account with the apple mail app on iphone running ios 13. To be fair, he did at least try it on his device during our chat session - he composed and sent a new mail from his phone, and immediately confirmed that there were 2 items in the sent items, and when he clicked on the one at the top, it duly disappeared. However, he couldn't confirm if engineering were looking at it, and just said that hopefully it would be fixed, and that he couldn't escalate it himself.

As well as the duplicate sent items issue, there is another glitch I have noticed: If you receive a new e-mail, click on it to open it and quickly delete it before it is marked as read, nothing happens and you need to delete it again for it to be deleted.

You would think such an obvious and silly glitch as to show duplicate mails in sent items that has come in with ios 13 (was NOT there before) would mean apple and microsoft would investigate, update status in a tech article, and then fix it. It's an apple change that has triggered it, so really the onus is on them - they should at least communcate something.
