I have my Hotmail account in the MAIL app on MacBook Pro, iPhone and iPad. Since some months every new mail I send appears twice in the SENT mailbox. It started with macOS Sierra and it's still occurring with Big Sur. This is driving me crazy. Can anybody help me?
Thanks.
(PS: I'm from Italy, sorry for my bad English)

Hello Gianpietro66,
It looks like when you send messages on your Mac it appears twice in your Sent mailbox. Making sure your mailboxes are showing the accurate messages is important. We're glad you reached out for help.
Take a look at the resource below to rebuild your mailboxes to see if that helps.

Hello,
my email account is Hotmail.
Actually I had never noticed what happens if I use it via a web browser, so I tried few minutes ago: I can see the same problem with the double messages. Then I assume that the problem stays in the mailbox itself and not in the Mail app.
I'm afraid that I asked to the wrong community!
Sorry for that.
Kind regards.
UPDATE:
when I wrote the previous message I had only checked the existing messages in sent mail and they appeared twice.
Then I tried to send a new message from the web browser (Safari) and it only appeared once.
Then I assume that the problem is actually in the Mail app.
Kind regards
Gianpietro66,
We appreciate you following up with that information. What type of email account are you using, such as Gmail, Hotmail, iCloud, etc? If you go to a web browser, Safari for example, and log in to your webmail do you see the same issue?
Additional information about the account and what happens in web browser will be beneficial to finding out the next steps.
Take care!
Dear kareng12,
thanks for your feedback. I had a look at the resource you had suggested, followed the instructions, but it does not help.
The messages still appear twice in my sent mailbox.
Any other ideas?
Kind regards
Hello,
I could not find those settings in the Mail app in Big Sur, but I find it on my iPhone (I guess you meant that).
The option "On the server" is already flagged and nothing changes.
Best regards
Gianpietro66,
Thanks for reaching back out with those updates. We're glad to see what else we can do to help. If you go to Settings > Mail > Accounts > [Hotmail Account] > Advanced, do you see an option for Sent messages? If so go ahead and see if you have any options to change to "On the server".
If those options can be changed test sending a message from your device and see if it corrects the duplicate messages in your "Sent" folder.
Have a good day!
Gianpietro66,
We're glad you let us know that setting. From here reach out to Apple Support here:
Take care!
