IOS13 Mail outlook.com duplicate sent items

I deleted my account and reinstalled it and now I am no longer getting duplicates but I am also not getting several of my usual subscription posts. ANOTHER FAIL!!! This is ridiculous.

This is persists in ios 13.1.2. I use an iPhone 8 and it’s only exchange mail that duplicates sent items.

Called Apple and created a case. They are aware of the problem and their engineers are working on it. I'm hoping we see iOS 13.2.1 in the next few weeks.

I have iPhone and iPad both on 13.1 but only the iPad is showing duplicate sent emails. It’s not actually sending duplicate emails confirmed on G-Suite webmail. Deleting account from iPad did not resolve.

That suggestion didn’t work for me either. I’m also on iPad 13.1.2 having to delete inbox twice, although only one shows in deleted items. I guess it’s the same issue, a local copy and a server copy.

I can’t understand why this isn’t mentioned widely in reality not that many users reporting here. ?

ive given on my iPhone and moved to outlook different but works well. Need to keep account just for contacts if you want iMessage to see them.

Having this same issue - all of a sudden with iOS 13.1 (on an iPhone 8), the Mail app shows duplicate copies of sent emails from my Outlook 365 account of emails sent via the phone. Emails sent from the account via PC only has one copy. Does not occur in the Gmail account I have though.

I stand corrected. Happens with my O365 company account as well as my Outlook.com and it bugs me A LOT. Removing the account from the phone and adding it again, doesn't help.

Fun fact, Microsoft Authenticator gets its MFA notification twice, for same account.

This started happening to me yesterday. Duplicate sent messages in outlook sent folder in mail app. IOS 12 was ok so guess IOS 13.1.2 is the culprit.

i was going to try deleting the account and re-installing it but note others have said this did not work.

my Outlook reminders have also all gone crazy, duplicate reminders and not syncing between devices

so far my outlook calendar is OK.

i much prefer using Outlook for mail, reminders and calendar as my husband has an android phone.

i see people have commented about using Outlook instead, do they mean downloading the Outlook app?

i have lodged a complaint via Apple feedback about the duplicate sent emails

I have not bothered live chatting Apple as am fed up of being told I am “awesome” and that they “understand how frustrating the issue is for me” before they leave me on hold for ages and then blame Microsoft or my phone provider.

Apple has focus in forcing users to update with reminders. Neither corporate or end users have the option to test beforehand or even the option to revert to prior version. I find it insulting for a Company Like Apple which came in with 3 versions within a period of 1 month which are buggy... Blackberry admitted their faults... Microsoft admitted their errors... Apple, lets delete the complainers and keep it out of press. New ver 13.1.2 is full of bugs and not just duplicates but also rendering of web sites.

I am still shocked Apple not looking at Apple communities and some moderators are deleting opinions which faults apple - They deleted 3 of my messages.

Chiming in. Same issue, with one other weird thing. When performing an action inside a email message I have to hit the command twice. Delete, move, whatever must be performed twice. Confirmed this is only on my outlook.com account, Gmail works fine.

Interestingly these issues are not happening to all iOS 13.x users in the World... We are a law firm in Delaware running about 50 iPhones on Exchange 2016 with Airwatch MDM. Our colleagues across town are running Exchange 2013 and do not have the iOS13 bugs we are all discussing here... One thing I have yet to hear from anyone is carrier - I am on Verizon with these problems. Anyone else out their on AT&T or T-Mobile devices or other carriers with the issues? Anyone out there on Exchange 2013 on prem with this issues?
