Mail app keeps crashing after Yosemite update

I can't even get mail to open any more. I get the Spinning Wheel of Doom, then it crashes. Ditto with the calendar app. This is a new issue for me after upgrading to Yosemite a couple weeks ago.

ok so I have solved my problem.

The issue is with the user Library. I opened a new user and ran my exchange mail on mail. NO problem!

so the make sure, I backed up everything ( most of my work is on dropbox anyway ) and then went about going through the process of formatted my Mac HD drive, doing all the resets and then a fresh install of Yosemite as a new machine.

I ran exchange mail for ½ a day as a test. ran perfectly. everything on the machine is so fast, and my machine is 5 yrs old. I have now loaded everything back, still no problems, and then 10.10.1 came out. Updated that and still everything is working fine.

so the problem was in user library, prob something corrupted, wasn't hardware thankfully, but to look and find that part of the library that was a the problem would of taken ages.

so if you have a day, start again, with your apple ID everything gets back to how you had it.

Hello,

Thanks for this update. Could you please be more specific, WITH DETAILED STEPS, on what you did? I would appreciate it. Thanks.

Hi I am having the same issue. I know you are not helped with it but I am using MacMail for iCloud and Gmail and Outlook for Exchange related mail.

Did someone from Apple Support replied to this subject..?

I found a workaround that worked for me. Use at own risk!

1. Delete the accounts.plist file under users>your account>library>mail>v2>mail datat>accounts.plist

2. open mail, it will ask you to add new account.

3. close mail

4. open trash

5. right click on the accounts.plist file and select put back.

6. open mail, and should not crash.

After this step:

2. open mail, it will ask you to add new account.

should you fill in the proper account into? or just close mail at that point?

Yep, do not add any info, just close it. The plist file will get put back in the next couple of steps. This has all your email info. Good luck!

Just to be clear:

1. After you open mail and it asks you to add a new account, you need to hit "cancel" ... after which Mail automatically closes. (That's what you mean by "close mail," correct?)

2. When you go to your trash and "right click on the accounts.plist file and select put back," it asks you to keep two copies or replace the one now in the folder with the one that you've trashed. You're instructions are "put back" and to choose "replace," correct?

Yes, replacethe existing with the file from trash.

Alas... didn't work for me. But thanks for sharing.

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.

Feedback

I have the same problem, it crashes when I read some emails, crashes when I respond to others. In each case I fill out the crash report and send it to apple. This has been going on for months now and I don't see any updates to the app or responses from apple. I give up and have switched to Thunderbird for Mac OSX. Thunderbird is free, integrates nicely into Yosemite, is as functional as the Mail app and most importantly doesn't crash.

Exactly the same here. i phoned Apple, they made me re-create my mail boxes, it worked for a week or so and then Mail crashed again.
Thunderbird works fine...

It's a pitty.

Yup, I use Thunderbird exclusively now. It works great! Someday maybe Apple will analyze those stack traces from the Mail.app and fix it.

I have the same issue - and also Notes constantly crashes. Disabling gmail works for Mail, but not Notes. At this point, I've simply switched to Outlook - I can't keep wasting time with various work-arounds that don't seem to solve the problem. Apple needs to issue a fix for all these app crashes. Until then, I'm using other apps. Fortunately, I only updated my laptop to try out Yosemite. Not quite ready for prime time.
