iPhone: some emails in “All Sent items” showing as unread

I have been having this same issue for weeks and all signs are point to it being an Apple issue. I am using a Yahoo IMAP account and, like most, am having any email I send from my Mac, iPhone or iPad using this account end up in the Sent folder as unread. Any mail that originates from Yahoo's online mail app, however, appears in the Sent folder normally as read. I have been working with Apple support for over a week and they believe that there is a setting somewhere in my user profile that is likely causing this. We created a test User Profile on my Mac, sent some test emails and the problem did not occur. This leads them to believe that the issue lies somewhere in a setting or problem within the User Profile - possible as a result of the recent Catalina update. The problem now is that they cannot pinpoint whatever is actually causing this.

The idea of the user profile being the source of the issue is interesting, but that does not explain why the issue happens from Galaxy phones, and from Thunderbird. It might be that there is an option in the user profile which can change this behavior, but I do not believe it is the cause. The root cause I think is in Yahoo, and they must have changed some behavior on their side.

IMO - It should be fixed by Yahoo as they seem to be the only ones affected. If apple introduces a setting to address it, that's only a solution for Apple, but not for everyone else who is affected.

Interesting point. I guess in these times when the norm is for companies to always try to blame someone else (whether correctly or incorrectly) I never thought of that considering the fact that Apple basically said that it must be their issue. I am trying to upload logs from my Mac for their engineers to look at but have not been able to get them to successfully transfer (another issue). If I get something back from them I will post it here.

I have this problem too.

It is especially annoying because I receive notifications for new mail and now I get a notification every time I send a message.

It seemed to start around the time I installed Catalina (Nov 2019) so I assumed it was an Apple problem. But then I logged into a Yahoo Mail account directly from their website (an account that was not set up on Apple Mail) and sent a test message. It immediately appeared in Yahoo’s sent mail folder as unread. So I believe this is a recent Yahoo problem and has nothing to do with Apple.

i am in a windows 10 environment and I have seen a couple of comments that it happened when it begam-for mac users- upon installation of Catalina which leads me to believe it is an apple problem.

Again If i send myself an email from yahoo in the web brows - no problem

but when i send myself an email from ios app then i get two copies in my sent folder

And now I am seeing double sent folder meails when i send to external people as well - bit only when i send from stock apple email.

Apple problem IMHO

even if you disagree, someone has got to step up and take care of this

You mean like the people who posted in this very thread that they have this problem on their Android phone? That was very helpful. And the people who posted that they had the problem using Thunderbird on their computer? Also very helpful. And the people who posted that it only happens with Yahoo and/or AOL, and not with any other email services? Very helpful.

Interested wrinkle... I just downloaded Thunderbird on my Windows laptop and sent a test message. The message did NOT appear in Thunderbird’s sent folder as unread. Everything worked normally on that end. Not sure what that means but I thought I would add it to the discussion.

It’s not just yahoo. I have AOL and it’s driving me crazy. I’ve deleted my account, added it back and nothing is fixing it. It has to be an Apple issue. I have 3 AOL accounts and it’s only occurring on one of them

Hi All. Not just Yahoo. Having the same issue with AOL. It's been weeks. Happens 100% of the time on my Mac (High Sierra), and only occasionally (I think) on my iPhone (iOS 12.4.1). Making me nuts. Glad to hear it's not just me. And clearly not AOL. Nor due to (either) recent system update. Just appeared one day, about 2 months ago.

Since you didn't bother to read the thread, I'll point out that AOL and Yahoo are the same, running (or not) on the same servers. Verizon owns both AOL and Yahoo, and Verizon mail (which also uses the same servers) has the same problems.

Yes, I saw that fact after I posted. For some reason not all of the thread had loaded for me, until after my post showed up. Tried to offer as much as I could to the conversation. Forgive me if my behavior wasn't up to your standards.

The unread sent email is more than enough. Now my incoming text messages are going to the unknown sender tab and then once I open them they migrate contact and SMS to tab. Apple needs to get this crap fixed. We spend waaaaay too much money on their products to have to deal with these nuisances

I am running an ancient MBP (mid-2009) with El Capitan, and I am having the same issue with the yahoo email (and not gmail, exchange, etc.). So, I don't see that is a Catalina related issue. Will be happy to see some resolution from wherever it comes.

Well, us guys are just users like you. And the fact that it happens on a Chromebook proves that it’s not an Apple problem or anything that Apple has any control over. Thank you for that insight.

How is Apple going to fix a Windows issue?

And if you want Apple to hear you this is not the place to do it, as Apple does not participate in this user-to-user forum.
