Sent items show twice on MAIL (IMAP)

Yes, it is a Microsoft feature, if you will, but what we are trying to do is find a workaround that is viable.

I too have this problem and it only started happening two weeks ago. Its annoying. If i select to stop storing sent emails on the server, it wipes ALL sent emails on my laptop and iPhone. Not sure why its only started happening now.

guys,

you simply need to deactivate option "keep sent messages on server" for your IMAP Hotmail account in MAIL preference pane.

Hotmail is keeping a copy anyway-

Hope it works for you as well as it worked for me.

Hello!

So after spending hours on the phone with Apple AND Microsoft support, neither were able to figure out the issue. However, I'm proud to say that I think I found the fix. (Worked for me anyways)

On your iOS device (for me it was my iPhone 6s Plus) go to:

-Settings

-Mail, Contacts, Calendars

-Hotmail (under ACCOUNTS) at the very top

-Account

-Advanced

-Sent Mailbox (under MAILBOX BEHAVIORS) at the very top

Now make sure you have the "Sent" at the very top checked under ON MY IPHONE

Now exit out of everything and try sending an email and you should only have one message in your Sent folder instead of the two. Hope this helps!

I've been dealing with this for awhile on my MacBook (using Apple Mail) with Hotmail (IMAP). And I seem to have found the solution (but I'm surprised no one else has, since it was quite easy...almost to easy).

Here is what I did: On my MacBook I went to Mail >> Preferences >> Accounts >> selected Hotmail >> Mailbox Behaviors >> unchecked "store sent messages on the server" >> and selected "never" for "delete sent messages when:".

Then I ran some tests: I sent an 3 emails, 1 from my Hotmail account in Apple Mail, 1 from my Hotmail account on my iPhone, and 1 from the Web-version of hotmail.....all which resulted in only 1 sent message. Then I checked my sent folders on all devices to see that all 3 emails were represented in sent folders for Apple Mail, my iPhone, and Web-hotmail....which they were.

Problem solved on my end. I'm curious if I've missed something here or if this fixes the issues others are having.

I followed your line and returned the same results as you. This works for me for now.

Thanks

"store sent messages on the server" is part of the fix for the issue here but the real bug/issue is that MacMail stores the sent item when you click send and then afterwards resyncs with the server, picks up there is another new item in the sent item mailbox (the one we just sent) and downloads it creating the dupe. That is what is happening. I want the sent item left on the server so my other devices can see the sent message and NOT have my sending device clean up after itself by removing it from the server.

_edit: further tests with checking the delete from server option cleans out the whole of my sent items on my mac. Rechecking it will show them all back up.

Actually this is not an Apple issue. Every time i have seen this issue it happens at the website as well. One needs to check to see if it is happening on the server. More then likely it is. They need to contact Microsoft.

That's not true because in web version of outlook that does not happen. Neither it does on my iPhone because a different sync technology is used.

The problem seems solved by unchecking the "store sent messages on server," but in my experience, that does not solve the problem. I get the duplicates when REPLYING to emails sent to my hotmail accounts. When I send an email, it does not duplicate. When I reply to an email, I get the duplicates. Called Apple support and the woman told me she's never heard of this problem. LOL. Then she gives me a microsoft number to call and it's an automated answer which hangs up on me after telling me to go search the web.

Thank you, this worked for me!

Had the same problem after I changed my iPhone. It is an iCloud issue.

On your iPhone > setting >iCloud, disable mail.

On Mac >mail >preferences >accounts >iCloud >uncheck "enable this account".

This worked for me, no double emails. Plus i don't need my mail to be saved on iCloud, if its already saving everything on its own. hope that helps

Is there a setting to "Send copy to self"?

I tried all the solutions presented in this thread and nothing worked. Still getting duplicate sent emails for my outlook.com account in OSX Mail app when replying to email.

Interestingly, I ran multiple tests using the same process, one tested on the Mail app in OSX, other on my Mail app on my iPhone and the last using outlook.com on a browser, and this problem is definitely only happening when replying using the Mail app in OSX. This leads me to believe it's an OSX Mail-specific issue.
