I'm finding in Yosemite Mail that the "Organize By Conversation" view is useless because it is grouping together unrelated emails. I can have two separate threads of email discussion - featuring unconnected contributors - but Mail elects to combine them into a single conversation thread.
How can I stop it doing this?
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.
I have the same issue. Unchecking "include related messages" had no effect. There is absolutely no logic behind how it could be grouping some of these messages. They are unrelated in every possible sense, from the subject, to the mail content, to the senders. This started happening immediately after upgrading to Yosemite.
I also was having this issue. I fixed it, at least for now, by switching back to classic layout in Preferences > View and unchecking all the options under View conversations. I quit Mail, then restarted it. Went back in and unchecked Use classic layout and set the other preference the way I like them. This fixed the problem. Hopefully it will stay fixed!
Sorry to report that this failed about 15 minutes after I tried it and the grouping is now screwed up again!
I have the same issue. Exchange email for work.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
What is the best way to send them feedback? They don't make it easy. Thanks.
Same problem here. I don't even know yet how many emails I have missed as they were hidden in random(?) threads.
Unchecking "Include related messages" did not help at all.
I am using "Expand all conversations" to at least see the (un)related mails in the left column.
Apple should take this serious as mail is not exactly a role model and people will switch to other mail apps.
Same problem as described here. We had to change my work email account from the exchange server to an IMAP account and that's when the trouble started. Changing any of the settings does not solve the issue. I will try to contact support, just to increase the number of complaints. Also have our Apple IT guru looking into it. If we find a fix, I'll report it here.
Click the blue link in my last post.
Oh, yeah. Thanks.
I clicked on OS X (since there is no Mail listed), and there is a "Mail" option under that page.
I have exactly this problem also. Unchecking the 'include related messages box' makes no difference at all.
This all started immediately after upgrading to Yosemite. I wish I hadn't. I have one thread of work email with ONE THOUSAND EIGHT HUNDRED AND THIRTY NINE merged messages that bear no relation whatsoever to each other.
And Apple apparently don't care or want to support this issue? :-(
Just to bump and say I have the same problem, have completed the feedback link as suggested.
How annoying!
Just upgraded last night. I'm having the same issue as everyone here. I've also tried all the things everyone has tried. I guess for now I'll just go back to using my mail like I'm on Lion or something. If anyone figures out some more things to try, post them here. I'm all ears.
Oh one more thing...is anyone else using Gmail fed into Mail? I know they don't always play nice. Could that be part of the issue?
Hi Murru
I use Gmail without any issues. But as everyone here has mentioned, since I upgraded to Yosemite I'm having the same issue where conversations are just mixed without any logic 😟
I don't have any idea why, but Mail seems to work regularly again, after I had switched to Mailbox (which was good but is less well connected with iCal and some other apps I am using, like Papers, Things). It does show the threads correcty and does not mix in unrelated mails, since 2 days now.
The only possible related change I made was that I had made Mailbox my default email client (in the settings of Mailbox, but probably it does not matter where that change is made) and then switched back to Mail as my default client. Maybe worth a try...
Good luck!
