Mail: Organize By Conversation - wrong emails

2017 and still happening in iOS Mail. (For some reason, the Mail app on my iPhone still sticks messages in threads that are completely unrelated, which is insane and I effectively lose track of a lot of email that way.)

Thinking maybe it's time to move on to new pastures...

Has anyone continued having this problem despite switching Mail software?

My mail is grouped 100% correctly online on Google Mail.

However on all email apps it was mixing up my mail.
I started on Spark then moved to another 3rd party Mail app, then tried Apple's own, and this issue was still there.

It led me to look at what is the constant between all the software. I nailed it down to the system clock.

My system is grouping messages incorrectly because I run my system clock +12mins fast (sounds silly but its beneficial to me to feel like Im constantly late...). So the system time doesnt match the 'real' international time, and it creates a weird vortex of mixing up groupings and email trails in incoming and sent messages on all of the applications.

Reverting my system clock to the 'set time and date automatically' setting resolved the issue across all software.

Hope that helps someone out. Was driving me crazy.

Hi Richard Carr,

Thanks for the question. If I understand correctly, you want to turn off Organize by Conversation. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

Mail (Yosemite): View conversations

Turn conversations on or off: Choose View > Organize by Conversation. A checkmark next to the command indicates conversations are on.

Thanks for using Apple Support Communities.

Have a great day,

Mario

Richard, I too was troubled by this until I discovered that under Preferences -> Viewing there is a button that is seem to be checked by default "Include related messages". Uncheck this and all will be back to the way it was before.

Sorry to hear that. It solved my problem: unrelated threads are no longer mixed. Good luck.

I have been having the same problem as Richard. I followed the advice of uriiam and unchecked the "include related messages" option. This "seems" to have fixed the problem. However, then what is this option for. It was linking things that have ABSOLUTELY NO RELATION. Not the same subjects, recipients, or message body, etc.... Literally no relation between the emails and yet, they showed together.

I also have this issue. Noticed it a few days ago. The email Subject is completely different. I am missing emails from people because they are hidden within a conversation of another email! I have switched off ""include related messages" but this has not fixed it for me. Its only a couple of emails, but nevrtheless its important for work, I cant be missing emails from customers.

I dont know if its related, but previously when you hit the little arrow icon to expand individual conversations, the emails were indented a bit, so you can see they are part of the expanded conversation. Now they are not indented for me, and because its mixing up unrelated emails with different subjects, when I do expand a conversation i cannot easily see where this conversation stops, and which emails are part of it.

I have the same problem, also after unchecking "included related e-mails". And what's just as annoying is that my replies to e-mails in the conversation are no longer included, and so I have to find them under "sent e-mails". This all happened weeks after I installed Yosemite, which seems a little weird to me.

I did a little more research into this.

• It seems that this problem has troubled people even before Yosemite. For some reason Apple's not getting the definition of a thread correctly (OK, it might be tricky but still...) and it's just getting worse instead of better. In my case Yosemite's Mail is joining threads that are obviously unrelated. Somebody there needs to put some "I" into their "AI"...
• Yes, if you uncheck the "include related emails" then your replies are taken out of the conversation which is annoying.
• I wish they would add an option to specify to Mail: this email is not part of the conversation and alternatively this email is.
• As a bandaid I customized the toolbar adding the "Conversation" and "Show/Hide Related Messages" icons. Most of the time I set both to off. When I quickly want to look at the whole thread I click the "Show/Hide" icon (and yes, it still brings unrelated messages if those were added to the thread) and/or the "Conversation" icon. It's not elegant but it works in the sense that I can see the whole thread when I need to and I don't risk missing any messages as mentioned above.

I have experienced the same issues. The problem was with my work e-mail. I used imap settings in mac mail for the account and got the conversation problem. I deleted the account and then tried setting it up as an exchange account and the problem was gone.

I have this exact issue and the problems started after the Yosemite update. Before that I had no such issues. This is very very irritating problem. I have set up the email accounts as IMAP.
