Mail not working after update OS X 10.10.4 and IOS 8.4

I ended up unchecking my gmail account in Mail Accounts and then relaunched and it came up fine. Once it was up, I merrely went back into Accounts and re checked the gmail account to make it live again and it worked. We'll see for how long.

This MUST get addressed by apple as this is a big enough issue that it had me thinking I needed to go out and get a PC as a backup for the MAC, that's not good.

Pressing SHIFT while starting discards pending context. Same trick works for example with Safari to avoid re-opening of previous pages....

My Mail has just gone from bad to worse with 10.4.4 on MacBook. The shift trick works WHEN Mail crashes on hanging on "opening mailbox" (I leave activity monitor open to see why I'm failing). If I don't hold shift and this happens Mail just gets stuck and trying to quit causes it to hang (need to force quit). Holding shift will allow Mail to get past this. But beyond this I have constant and intermittent connection problems with multiple IMAP accounts. And its not the server nor the connection. I have my mail accounts synced via iCloud, and the exact same connect and work perfectly in Mail on MBP 17" running 10.9.

I am really starting lose patience, this has been going on since I got the MacBook months ago. And 10.10.4 just made things worse. And there doesn't seem to be any fixes coming along. On a MacBook, which is only good for Mail and light surfing anyway, I can't use Mail reliably!

That is interesting Edmund. I also have IMAP email accounts with AOL and BT (British Telecom). In the last month, some outgoing emails have not been delivered, and some incoming ones have either not arrived, or have arrived up to 24 hours late. I choose to display both the Date/time sent and the Date/time received, to provide proof of lateness. It tends to be certain senders' mail that arrives late or not at all: some daily newspaper bulletins for example, but also text mail from certain individuals. One email from BT itself took nine hours to arrive into my BT IMAP account. But the majority of emails on these and other (POP) accounts are coming and going promptly as normal. Both AOL and BT both deny that the faults could be with their mail servers. I had not associated these problems with the empty mailboxes fault, but perhaps there is a connection. I am using 10.10.4 but the empty mailboxes started with 10.10.3.

So, I think I found the source...I have about 23 emails, 19 are email and 4 are 1and1.

I removed all but the gmail accounts. To do this and not let mail LOCK UP, I turned off then internet. Then I closed mail and restarted it. Then I turned the Internet back on and NO PROBLEM. I didn't have to hold shift.

It seems that Mail was trying to use the 1and 1 accounts WITH SSL and Port 143. We all know that it should be 993.

I then ADDED the 1 and 1 IMAP emails MANUALLY specifying correct ports and NOT CHECKING the box that says "detect and maintain settings"

All then worked find for me.

HI,

I'm french and I have an iMac and a Macbook Air. I have same problems. I can't read and write any mail on my two Apple. I can only do it on my iPhone but it's not very practice.

I'm very sad because I use it for my job and for my private messages. For 4 days, i'd searched explications on french web sites but I had found nothing about this.

But eureka !... I'd found you site.

I tried all solutions but nothing. I still have the same problem.

I hope that APPLE read us and find quickly solutions ! I can't write 30 mails per day with my iPhone !!!!

I'm very disappointed by Apple

had the same problem with the mail app on my ipad and many of the recommendations listed here are for other mac products and don't apply to my machine. i tried everything and what finally worked was the following:

quick, double-click start button. when the apps appear on screen, flick all of them off (first time i tried this i only flicked off the mail app and it didn't work) -- could take a while. then restart.

hope it works for you.

I installed the update on MAILBOX (beta) which had been working, and now it does not work at all on the MacBook Air. It just starts to load, then goes into "Mailbox quit unexpectedly" and keeps doing that until I quit that loop.

Its very frustrating.

if you know a fix, let me know

If not, can I have the OLD beta back

Mail, Prefs, Accounts, Advanced, and "automatically detect and maintain account settings" did not help me. In fact, that box has always been checked and still my emails are being placed in the Archives folder, then the "Important" folders for two of my emails. This is frustrating because it means having to open up those folders all the time to check to see what emails are there....I had found some fix in the past, at the Google Mail level, unchecking certain folders, but I lost that fix...

Does anybody else have any fixes? This has been happening to me for at least a year now..

It could be a conflict with mails saved prior state when you updated OS X in which case you need to delete the prior saved state:

1. Force quit the Mail app
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

I am using MAILBOX beta not MAIL program. I need a fix to that one
