First Steps to solve mail app keeps crashing with El Capitan
Simple is indeed better. Thanks to our reader Kal for this quick tip! So before you do anything, turn off all your email accounts without even opening the Mail app at all, by going to System Preferences > Internet Accounts and disable ALL your email accounts.
WARNING: Deleting an account or turning off individual account features might remove data stored in your apps. If you sync with iCloud or turned on sync with other providers (like Google), your data is stored on their servers so your data loss should be temporary.
To remove an account and turn off all its features, highlight the account and click the Remove button. If you delete an account AND your Mac has iCloud Keychain enabled, Apple also removes this account from your other Mac computers set up for iCloud Keychain.
After disabling all accounts, try opening your Mail app. If Mail app works, the problem is with one (or more) of your synced email accounts. So then turn on each email account one at a time and open Mail to see if it’s working after adding each account. As you add accounts, this process should reveal the culprit—for Kal; it was an Exchange account he didn’t use or need anymore.
If removing internet accounts didn’t work, follow the steps below to troubleshoot this issue further
Mail App Keeps Crashing with El Capitan? Check Damaged Email Havoc
One of the common causes for the problem of mail app keeps crashing with El Capitan is trying to open an email that is damaged due to some reason. The chances are that Mail may continue to crash as long as you have this email in your folders. It is hard to pinpoint which of the items may be causing this issue. If you see an email from a sender that you don’t recognize, or your app crashes when you try to open this email, this could be the culprit.
Step – 1 Open Mail
Click on your Mail app to open it and immediately hold the Shift key until Mail opens. This causes your Mail App to open without any message or mailbox selected
Step – 2 Hide Message
Hide the message viewer portion of the window by carefully dragging the thin separator bar between it and your list of messages. Keep dragging until Mail shows only the list of messages, not the message viewer. In this view, you can see messages only by double-clicking to open the message.
With this step, you may need to reset some of your personalized formatting options, such as reviewing your Mail Preferences and resizing your window panes, and width of columns etc.
Step – 3 Select Message but DON’T OPEN
Click the affected message once to select it without opening it. Then press Delete or choose Message > Move to > Trash.
Step – 4 Close Mail
Now Close your Mail App and Try opening it normally.
If the Mail crash issue was not related to a particular corrupted email, then you need to follow the following steps to make the application work. Please note that you may have to recreate your custom stationary after following the steps below.
Step – 1 Open your Finder App
Click on Go and Go To on the Top Menu as shown in the image below.
Step – 2 Type in “~/Library/Containers” and press GO
This opens the various application container folders. Drag the Com.Apple.Mail folder out of here on your desktop.
Drag the folder onto your desktop.
Step – 3 Repeat Step 1
Follow Step – 1 from above BUT this time around, search for the following file “com.Apple.MailServiceAgent’. Drag that file to your desktop.
Step – 4 Restart your computer and check the Mail App
This usually fixes most of the sudden crash issues on your Mac. If you are still experiencing mail app keeps crashing with El Capitan or similar problems, consider re-installing the app into your Mac. Or set-up a visit (or chat) with Apple Support, at an Apple Store, via telephone, or on-line.
