Sent items show twice on MAIL (IMAP)

I'm not guessing. I know it works with other providers, but it doesn't with microsoft because mail for OSX does NOT support activesync!!! Whereas mail for iOS does!! Do you understand now what I meant?

You are badly misinformed, Microsoft do not offer EAS for OSX.

DO you read or you are just writing what you want? that's exactly what I've written. It's only supported on iOS.

Because Micrisoft want it that way, Apple can only use what Microsoft provide, and they don't even provide EAS for Windows, let alone OSX

Exactly what is it that you want Apple to do?

Any solution found yet? Never had this problem w iPhone4 yet iphone6 intro'd it. Mail recipients keep asking why they're getting my emails twice and I have no answer other than its a fault of the suppliers who according to this discussion site, don't appear to have an answer in over two years. Poor show!

I Found that I was getting duplicate emails in my sent box on my iPad, but have just cured the problem by going to Settings, Mail, Contacts, Calendars then Account, Advanced, Sent mail box and un tick the Sent box so that it says 'on my iPad'.

I have an iPhone 5s and I'm using hotmail "not" outlook and I still get sent emails twice in my folder. How the **** can I fix this it's really frustrating.

Which server address are you using.

Thanks a lot. It works perfectly.

Try what I did on my previous posting. It might help.

The best solution I have found to date is to only use the Outlook outgoing server. Using an alternate IMAP server risks having the email flagged as spam as some spam filters (client and server side) consider relaying, and mail sent from a server other than the correct originating email server, spam. I have recently had mail look like it's sent and not received (intercepted by server-side spam filters that recipients don't see. It also risks having the mail server blacklisted).

Untick "store sent messages on server" (in Mac Mail) and do similar on your iPhone (as in, store the Sent emails, "On My iPhone"). Note: I setup my iPhone 6 using IMAP, perhaps Activesync on the iPhone would work better in this regard.

The downside of this is you don't get your SYNCED Sent emails in the "Unified" Sent items folders (the ones with the paper-plane icon) on neither your Mac or iPhone, and you end up with your real sync'd Sent items in a Sent "sub-folder" at the bottom of the IMAP folder list.

The other downside is you can't view ALL sent items across all accounts in Mac Mail using the unified sent folder, but I find these bad for productivity anyway.

The upside of this is you end up with your duplicates in the "paper-plane" Sent folder on each your iPhone and Mac Mail as local copies that were only sent from whichever device. A nuisance perhaps to have to purge it once in a while, but simple enough.....or just ignore them.

Hope this helps.....I'll check this thread once in a while to see if anyone has a better solution using the correct outgoing folder.

I should add, many people above have said what I have, I just thought it helpful to summarise the best solution as I see it. Using an alternate mail server is a better option (which I did for a long time), but I started getting more than a few people not getting mail, so to avoid being flagged as spam, I've used the option above.

This happens to me using a live.com account with Mail.app on OS X 10.10.5

Am still having this issue even on el capitan mail app. Is it the problem with Microsoft?

I believe this works. Thatnk you Applicability. Good work and good stick-to-it-ness!
