Mac mail will not open or close

A quick guide to fixing El Capitan Mail problems

Upon restarting, most of the time Mail would function OK, but occasionally hang again, always with the same error— Application Not Responding.

I left the Mail Preferences window open to Accounts. Now, when I restart the Mac or it starts up automatically in the AM, Mail launches as per normal, but with the Preferences window open to Accounts. No problems since. I came upon the fix by disabling all email accounts, re-enabling each, one-by-one, then doing a shutdown and startup.

About five re-boots in I inadvertently left the Preferences window open to Accounts. No freeze on the next reboot. When I close Preferences, the freeze begins again. You solution works for me. I tried all the tricks that helped… until I restarted the computer. I tried the moving the folder in Containers etc. Worked once. Now back to the same old Freeze. Ron Mac mentioned the Mail Preferences: Your page is a potential life-saver — thanks! Any ideas? I have done a clean install of the system plus your tip, but no good. Please, keep in mind the possibility that another app is crashing, too.

Meaning that this second app is the orogin of the problem. I got this with dropbox. Close all apps ru nning in the background and check if your crashing still occurs. Then activate one by one for identifying the second crashing app.

Thanks to your help I revived Mail but now it works but I have lost all my emails, rules, mailboxes etc. Any ideas what I can do to recover them? Check your email in your web email client. Are they still there? They should be if you have used IMAP.

Most curious. I also tried what you suggest on that linked page, but no dice. Wow thanks for the fix! I thought gmail was the issue.. Have you posted on apple forum or support?

Problems sending messages

In regard to your suggestion to post this in the Apple forum: However, if somebody else will do this, he could do it. Thank you for this fix. I have tried lots of various fixes and this one finally worked. You have saved me numerous hours of reinstalling and fixes.

Mail won't open or quit so I cannot shut … - Apple Community

Thanks again! Hi there, unfortunately this has not worked for me. Do you have any further suggestions please? Yosemite It shall fix some email issue. Update and let us know if your issue is solved. I even upgraded to El Capitan hoping that it will solve this issue. I went up to Public Beta 4 in El Capitan and then in the latest update the whole system crashed in a start up and I was only able to use it in Safe Mode! Then I downgraded back to OS Yosemite and after seeing again this problem. This is a good solution.

If you have any open email windows, they will be closed upon next startup of Mail. This is because the savedState folder contains information about naturally the last saved state of the app, which includes what windows were open, what position on the screen they were, their order, etc. All superficial UI stuff, but could be important if you, like me, keep individual email windows open as a reminder to reply to them. There is for example this thread: But in this case it freezes because something about dealing with multiple folders on the exchange server is too much for Mail.

By reducing the number of folders on the Exchange server, you stop Mail from frequently hanging.

Problems receiving messages

And many thanks for your feedback that Gmail is a source of the problem! And the OS update breaks mail? Our tech person at the organization providing us with hosting services told me yesterday that they have a number of customers with Mac mail problems similar to those reported here. July 5, at 4: Same exact problem. Excellent explanation and a fix that really worked. I have yet to figure out how to transfer and setup those in T-Bird.

Unfortunately, this has not fixed unresponsive Apple mail in By resetting PRAM and restarting multiple times, I sometimes can manage to get it working but still no clear process for a permanent fix. Hope to see this resolved. Thanks for the great blog. This has not worked for me. Simple fix and it worked on OS X Yosemite vers. Much obliged for the assistance. Many thanks.

Worked first try! Thanks for the hint. Back to work now, smiling. Keep up the good work! Thanks again, Jochen.

Help please: Can't log off because Mail won't shut down, can't get into Mail to shut

The only think is that I had to shut down then only restart instead. Thanks for your reply, bookmarking and sharing miapple. BTW, if you got some problems to solve, just contact me! I bookmarked this page just to come back and say this worked for me. It worked the first time, but problem came back.

Thankfully I can just re-delete. Did the problem come back for you? Have you already check the other tweaks mentioned in the linked posts?

How might we stop the creation of the file? I have figured out that I can launch by holding down the shift key and double clicking my Mail launch icon, and this seems to bypass previous preferences I am assuming and launches fine. Perhaps one of you fine smart folks might know a way to make that permanent and eliminate my workaround?

First, let me thank all of you for great work and input. Secondly, I can say that I have had more trouble and experience than anyone here. I have over 60 e-mail accounts running in Mac Mail — and yes — one could argue that this is my biggest problem, but alas — not the case: After experiencing every possible issue too long a list to report incl.

Hope this helps….
