Mail unusable since upgrade to Sierra

When I first upgraded my iMAC to Sierra (10.12), Mail would crash every time I tried to select the "Sent" folder. Most other folders could be accessed fine; a few would also cause Mail to crash. Re-installed Sierra, no luck.

Today, Mail started crashing on a few other folders. Then, finally, it crashed altogether and will no longer re-open; every time I try to open the app I get a "Mail quit unexpectedly" dialog and dump. I believe this is the most pertinent information:

Crashed Thread:        6  Dispatch queue: com.apple.root.default-qos

Exception Type:        EXC_CRASH (SIGABRT)

Exception Codes:       0x0000000000000000, 0x0000000000000000

Exception Note:        EXC_CORPSE_NOTIFY

Application Specific Information:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]: unrecognized selector sent to instance 0x7fffb4d7cf10'

abort() called

terminating with uncaught exception of type NSException

Once again I re-installed Sierra, but still cannot open Mail at all. Any thoughts?

If you're also crashing in Address Book, that could very well be your problem. Try moving the ~/Library/Application Support/AddressBook folder to your desktop and/or delete it and see if that makes a difference.

Good luck!

Hi PTDiMarzio,

Thanks for using the Apple Support Communities.

You can fix Mac OS X 10.12 Sierra Mail not responding (“Mail quit unexpectedly”) by removing the container folder ‘com.apple.mail.savedState’. Mac OS X saves window locations and open documents of most programs to restore them when the program is launched again after quit. Sometimes after upgrading Mac OS X to the latest version, there can be some handling issues with the prior saved state of Mail which could lead to Sierra Mail is not responding and crashing.

How to remove Mail saved state:

1. Force quit of Mail app (‘Application not responding‘ issue!).
2. Go to the Finder.
3. Hold the Option key and then select ‘Library‘ from the ‘Go‘ menu.
4. Go to the folder ‘Containers > com.apple.mail > Data > Library > Saved Application State‘ and move the folder called ‘com.apple.mail.savedState‘ to the trash.
5. Empty trash.
6. Restart your Mac.
7. Re-launch Mail.

Hope this will help.

Cheers !

Thanks for the tip. I followed the procedure to remove the folder but the problem persists. Mail will not open; it crashes while it tries to come up. I have verified that the folder is in fact gone.

Well, maybe it comes from multiple email accounts active in the app.

The initial download of all messages from all accounts seems 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 should stop. 

Hope it works !

Thanks for the continued help. I do have multiple accounts attached to Mail. I disconnected from the network (I'm hardwired but ensured wifi was not on and there was no connection active), tried to open Mail, and it failed as it tried to open - as it has been doing. So no luck.

Downloading shouldn't have been the issue anyway because I had already been working with Mail on Sierra for several weeks, so any download/indexing should have already occurred. For a time - immediately following the upgrade - the problem I had was a Mail failure when I tried to access the sent mail folder, but I could otherwise work with Mail just fine. Then I started getting failures trying to open other folders, and finally it failed on its own and ceased to start up anymore.

Well, I'm starting to run out of ideas

Maybe this will help then -> Mail unexpectedly quits when viewing certain messages

ok - now we're making progress!! With the shift key held, Mail does in fact open up and stay open. For four out of my five email accounts, I can click the account's inbox and use the message viewer, no problem. If I click on the inbox for that fifth account, though, it's immediate failure (I can't view the list of messages even with the viewer hidden). I'll still get failure on the Sent mail folder, and some other folders, but many folders I can view.

So now it's starting to look as if the database was corrupted during the upgrade, possibly for just this one account. Can   you point me to directions for deleting and rebuilding my local copy?

As a follow-up, I followed the procedures I found here (https://www.computerworld.com/article/2476217/mac-os-x/mac-os-x-how-to-fix-apple- mail-by-rebuilding-and-reindexing-the-ma…) to both rebuild, then reindex, the mail folders. I'm in about the same situation as I've been: I can work with my inboxes, but mail will crash if I try to see the Sent mail folder or about 1/3 of my file folders. Is there a process in place for totally scrubbing Mail, getting it to it's "first install" point, then re-adding the accounts as if for the first time? There's clearly some nasty issue on my machine and it's taking too long to track down! Thanks.

just go to " go " option key -> library -> rename folder " mail " and setup your mail again and it will work...

then have to see if there was mail in local folders to import them back. 

just done it right now on someones Mac Book Pro freshly updated to sierra

Thanks for the tip Cedric but the issue would seem to be with Mail files elsewhere. I did rename the mail folder and open up the app ... but I did not have to go through any setup process; Mail still knew about my accounts, even the folders. Yes it did go through the long process of downloading all the messages and rebuilding indices (effectively creating the mail folder again from scratch) but the app will still fail when I click on the Sent mail and certain other folders. So there is something amiss elsewhere, I just don't know where to look!

I'm also having same Mail app crashing issue after updating my OS to the latest Sierra version.

Need help.

Hi

This worked for me thank you!

Thanks for bringing this up. I've been having the same problem every since I updated to the new operating system. I temporarily solved the problem by disabling my yahoo account. Now when I click on another IMAP account, or the Sent folder, it crashes. I've tried all the suggested solutions here. The Sent folder crash is the last straw, though. I'm constantly needing access to sent emails.

The frustrating thing is that this is an Apple product, an integral link in the chain of apps, and the whole Apple "all you need is us" paradigm, and no one from Apple seems to care. As of today, I'm bailing from Apple Mail. I'll suffer at first because Apple makes it hard to integrate anything but their own products. But this is a serious fail with Mail on their part. It's now worse than some beta applications out there I've tried.

Keep us informed if you find a solution.

I actually started a second thread on this problem - simply asking for a complete list of Mail files and folders so I could do a manual removal. No responses.

Mail failures since upgrading to Sierra - how do I uninstall Mail??

A bit amazing to me that most OS X apps can be removed simply by dragging to trash, but Mail has so many tentacles throughout the system that it cannot be brought back to its original state and rebuilt.

I tried the phone service, was disconnected and never called back (even though I provided a call back number for this very reason).

This weekend I switch to Thunderbird. Apple, are you listening?

If you're also crashing in Address Book, that could very well be your problem. Try moving the ~/Library/Application Support/AddressBook folder to your desktop and/or delete it and see if that makes a difference.

Good luck!
