Sent items show twice on MAIL (IMAP)

Is your e-mail POP or IMAP?

it appears as though this problem was never solved!

im using an IMAP hotmail account and the Mail app on my iMac.

If you turn off "Organize by conversation" then the issue doesn't seem to present itself. I am sure Mail app downloads a second copy as previously stated but in the presentation layer at least it is not showing both of them. In the end I switched to another email client.

This can actually be fixed from the Outlook web site.

1. Go to outlook.com & login
2. Click the gear icon in the top-right and select Options
3. Under the Writing email heading, select Saving Sent Messages
   
   
4. Select the following option:
   Don't save sent messages. (But if you use POP to send Outlook.com messages from another service, those messages will still get saved.)
5. Click the Save button.

Works for me. macOS Sierra using an outlook.com account with the mail application.

I cannot see the writing email heading...

Here's what it looks like on the options page:

This is all I see. I cannot see writing email heading anywhere there?

Does your email end in @outlook.com or something else? I wonder if you're connected to an Office 365 (O365) account for an organization (like your work, or a school) which uses Outlook on the Web, but isn't the same as Outlook.com accounts.

My instructions above should work for a normal @outlook.com email address. I'll have to see what I figure out for an O365 account.

It's an @hotmail account, but I think hotmail moved over to outlook didn't it?

Your list of options looks totally different than mine (see screenshot). If you've had your hotmail account for a while, it could be that it's not using the new outlook.com look & feel.

Outlook.com Options Page:

Looking online, Microsoft indicates that in order to upgrade to the Outlook.com user interface, you must do the following (source from Microsoft):

How to upgrade

The easiest way to upgrade is to sign-in to Outlook.com:

• Go to http://outlook.com
• Sign-in with your existing Hotmail account (@hotmail.com, @msn.com, @live.com, etc.)

Hope this helps!

I have already signed in multiple times to Outlook.com. The look and feel is that of an Outlook.com account - my small issue is that sent items appear twice when sending a single message from the Mail application. Presumably this would be easier to fix if didn't use an @hotmail and rather an @outlook. But changing emails is a hassle! 😝

What worked for me:

Preferences > Accounts > Hotmail IMAP > Mailbox behaviors > Sent Mailbox > On My Mac: Sent

Before the Sent Mailbox was "Hotmail: Sent".

No more fake duplicates on Mail.

Thanks for your input. However I believe that by doing what you suggest, I will not be able to view sent items when using other devices (my phone and laptop).

Unfortunately this isn't a solution, it's just a workaround that only works for people who only rely on their desktop computers for email (I want all my email synced across all my devices).

I am having this very problem too! I have a @hotmail account, and when I log into outlook.com there is no heading labelled "Writing email".

It doesn't work for me. I have a hotmail account and there is no "Writing emails" heading when I log into outlook.com
