El Capitan has broken Mail

Since upgrading to El Capitan yesterday, Mail has been a total nightmare to use. It started with it crashing every time I opened it until I found a tip to disable all the email accounts and then re-enable only one, let it download all emails, then repeat the process until all the accounts were enabled.

That worked for about twenty-four hours. But now, I'm having a whole host of issues. Now whenever I open Mail, it slows my entire computer down to a crawl before everything just completely freezes. I've tried the disable/re-enable trick, but that doesn't work. I only managed to re-enable one account before my Mac completely froze up again.

Same happened to me, so i got my Time machine backup and returned to yosemite.
 
Oh apple what have you done (again)!!
Its as though every time these fools update and "improve" OSX they bust up mail. Currently I can't get gmail or iCloud to run properly in mail either - only exchange runs quite ironically.

It won't download or sync or delete any emails.

For the biggest company in tech this is actually just a poor show. I will be using the web browser interface or downgrade to Yosemite by the weekend if this gets on my nerves too much. I wish instead of coming out with the latest gimmick they actual do proper beta testing and bring out a working product.

I have other problems with 10.11 I won't mention. Apologies for the rant (thread jacking).

Mail has been running fine for me. Google, iCloud and Exchange have all been working flawlessly on 10.11.

I'm not saying you're the only person(s) with issues, all I'm saying is that's my experience. 10.11 has been running very well on my late 2011 MBP. I still have a spinning HD in my laptop. I also did a clean install of the GM then update to Public so not sure if that has anything to do with it. I typically do clean installs anytime there is a major rev (i.e. From Lion to Yosemite, Yosemite to El Cap). Also, I've always used Thunderbird for my email, as Mail always gave me probs in previous releases. For whatever reason, Mail has been quite stable this time around so I'm going to stick with it. I'm trying to use as much of the Apple ecosystem as possible.

Sure, don't get me wrong there are likely more who have had no issue, however for those of us that do/have it`s incredibly frustrating, and in some cases very time consuming. In general I have not had any major issues with an OS X OS upgrade, until 10.11 as I prepare the system prior to the upgrade.

A clean install is not strictly necessary, the way OS X functions, equally it does help to reduce the OS footprint etc. For me a clean install will require several days of work to bring the system back up to the same level, right now I am more inclined to do a clean install back to 10.10.5 as the more time I spend with 10.11 the more buggy it appears.

A good friend of mine always stays a full OS X version behind, which I am starting to think is "wisdom" he still gets regular updates, the OS is well developed, he very rarely has any issue. Given Apple`s overly ambitious 12 month cycle for OS X, his "mantra" is making more sense by the day...

Mail actually works better for me with gmail than it ever has. Before Mavericks, gmail setup was always a hassle, with Mavericks and Yosemite I had these mail blackouts. El Capitan just simply works.

I recommend you deleting all your account data, reseting mail and synching again. Maybe there is some weird config that got stuck. Also, check whether gmail might have blocked your computer from connecting.
 
so my mail issue is a different one to those already posted... When scrolling to the top of any mailbox, where it would normally have the 'rubber band' animation the messages just continue to scroll down with a white space above. Also, when I try to scroll through a specific message using my magic mouse, it just continues to scroll all messages even if i have clicked onto that message (but not opened a new window). It's very odd!

Try booting into safe mode, as this cleans up many caches. Equally the way OS X is going "Voodoo dolls" may be a viable alternative....

Anyone know how to group emails by sender? It seems since upgrading to El Capitan, all my emails are now showing up as individual. In Yosemite and all older, my emails were grouped by sender across all mailbox.

Please advise.

Are trying to group by sender or group by conversation?
 
When I chatted with Apple Support, they suggested I reinstall El Capitan, which of course did nothing. But fortunately, someone on the Apple Support forums had a solution. This completely worked for me and hopefully it will work for others who are having this problem:

Please take these steps to delete the Mail "sandbox" folders.

Step 1

Back up all data.

Triple-click anywhere in the line below on this page to select it:

Code: 
~/Library/Containers/com.apple.mail

Right-click or control-click the highlighted line and select

Services ▹ Reveal

from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selectedfolder—not just its contents—to the Desktop. Leave the Finder window open for now.

Restart the computer. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. Any custom stationery that you created may be lost. Ask for instructions if you want to preserve that data. You can then delete the folder you moved and close the Finder window.

Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.

Step 2

If Step 1 doesn't solve the problem, repeat with this line:

Code: 
~/Library/Containers/com.apple.MailServiceAgent

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Step 1 is the only one I needed to do and then the problem was solved.
 
Try holding shifting when starting the app (and continue to hold for a few seconds after the app starts) if you are experiencing freezes at startup.

There were major issues with Mac Mail an 10.10, and it usually had something to do with users having multiple (3+) g/email accounts in the app.
 
Can't register Exchange account. Says "unable to verify account name or password" though both are correct (checked by logging in on the web). iCloud and gmail are fine. Anyone has solution?
