Mail App keep crashing after install El Capitan

I had this problem and finally managed to solve it on the gmail end. I had 5 accounts, and when enabling one-at-a-time, one gmail account would instantly crash it. The last thing I remembered doing before the first crash was that I had deleted a bunch of spam but one had caught my eye that shouldn't have been, so I undid the delete. After that, crash in 2 seconds every time.

I went into gmail.com over the web and did these things. Not sure which one fixed it -- deleted all spam, emptied the trash, moved everything out of the Inbox into other folders. Then went back in to Mail.app and turned the account on and it worked ok.

I've been experiencing a similar problem and your solution (BartoloTX) has worked really well and I have managed to get all my accounts up and running. Except my main account that continues to crash my Mail. Do you or anyone else have any ideas around how I can resolve this? Thanks

Sorry I managed to find a way around. I turned off wifi. Enabled the defective account that was causing mail to crash. Deleted all Trash and Junk. Marked all messages as read. Also turned off an away rule that I had set up and now it's working okay

Ditto.

I had the same problem, but I believe I've fixed it. It's seems to have been related to the fact that I have multiple email accounts active in the app, as many people do. The initial download of all messages from all accounts seemed to be overloading the app, causing it to crash. See if this works for you:

1. Before opening the Mail app, turn off your wifi connection (prevents mail from trying to download mailboxes from all accounts at once).

2. Launch Mail app and go to Mail -> Preference -> Accounts tab.

3. Click each of your accounts on the left side of the Accounts window, then uncheck the box next to "Enable this account." Disable all of your mail accounts.

4. Close Preference and close the Mail app.

5. Relaunch the mail app and reconnect to wifi.

6. Go back to Mail -> Preferences -> Accounts tab, and enable the first account. Give the app plenty of time to download all messages until you no longer see "Checking for Mail..." at the bottom left of the app screen (may take a few minutes depending on how many messages you have on the server).

7. Once the app is no longer "Checking for Mail..." repeat this server for each of your other accounts. I saved Gmail until last since it's my biggest, which took the longest - about 5 minutes (I use multiple Gmail accounts).

After enabling all accounts, the crash issue stopped for me. Hope it works for you!

Hi - this worked for my iCloud account but then when I enabled my GMAIL account it didn't work. In Mail Connection doctor it says: GMAIL SMTP connection and login to server succeeded. GMAIL IMAP - Could not connect to this IMAP server. Check your network connection and that you entered the correct information in the Account preferences. Also verify that the server supports SSL. If it does not, deselect the "Use SSL" checkbox in the Advanced tab of Account preferences. Any suggestions how to fix this?

People, i followed BartoloTX 's advice and it works.

Thanks! x Monica

This worked for me, turning on the accounts one by one. However, overnight, having multiple accounts enabled in Mail, and leaving the app open, it terminated again.

I follow this approach and no improvement.

My problem appears a little different. Once I click on the Mail app icon, it doesn't even open any window or change the pull-down menus at top...it doesn't appear to have a chance to check any accounts.

So, something is preventing the program from starting.

Any other ideas? Thanks in advance!

Chris =)

I follow your steps but after restart I have the same problem again

Hi

I have exactly the same issue. Mail crashes within seconds of start.

I have tried to open without WiFi. Same problem.

The issue seems to be connected to gmail...

Does Apple really want us all to switch to Outlook???

Thanks for your help

I deleted my GPGMail.mailbundle file from Library/Mail/Bundles/ and the app stopped crashing on startup. So my first thought for anyone having crashing is to think about whether you have any add-ons (GPG in my case), that may be the culprit.
