How To Fix Mavericks Mail Unable To Connect Error

Mavericks Mail.app stopped being able to authenticate to any IMAP or POP mail servers -- my own OS X Server.app, iCloud, Gmail, etc. iOS clients could connect just fine, and I see that many, many others are having this problem as well. I solved this, but essentially by throwing in the towel and using these posts to bring Mavericks Mail and the login Keychain to their factory settings.
The following worked for me, and blowing away the Mail settings and Keychain were both necessary. If anyone has a less drastic solution, please post it. Make sure you backup any necessary certificates or messages before wiping this all out.
sudo rm -fr ~/Library/Caches/com.apple.mail ~/Library/Saved\ Application\ State/com.apple.mail.savedState* ~/Library/Application\ Support/AddressBook/MailRecents-v4.abcdmr* ~/Library/Containers/com.apple.mail ~/Library/Mail ~/Library/Preferences/com.apple.mail*
Keychain Access>Preferences>Reset My Default Keychain
I also used Disk Utility to fix permissions and did a safe boot to clear out a bunch of cache, though these steps didn't fix this specific problem.

I posted too soon -- this problem reappeared. Per this article and Apple support page, luckily a simple rekerberization of the OD Master fixes the problem. My fingers are crossed that it stays fixed.
This worked:
sudo touch /var/db/openldap/migration/.rekerberize
sudo killall PasswordService
# start Server.app, restart Mail

  • Mail Unable To Connect Error

    For the last day and half, I've been unable to access my iCloud email through Mail on Lion.  I get the following error:
    The server returned the error: The connection to host p03-imap.mail.me.com on port 143 failed.
    According to the system status, iCloud Mail did have an issue but apparently they think it's resolved.  Anyone have any idea why I'm still getting an error?  I have no problems accessing iCloud Mail on any other devices or through Safari.

    I did. The results remained - it didn't work for me. All devices, changing password, deleteing/re-adding acount, changing port/SSL in the mail app on my workstation, and on the laptop, even logging onto iCloud-online - no email, period. Eventually got support on the phone, answered a bunch of questions, sat on hold, got passed on to a supervisor, sat on hold for another while and they came back saying my email was in migration and I should be back online tomorrow - TOMORROW!
    I promptly lost it. Completely. I "migrated" weeks ago! And if that wasn't migrating what was I doing? Well, apparently although I migrated all my devices after updating software and had done everything right, I hadn't actually been moved onto the new iCloud servers and there was a bottle neck somewhere in the process that should have finished at 3:30 am without my ever being aware. Lots of apologies were extended but nothing could be resolved sooner - frankly I almost lost it again hearing this because the business day was over and I have no idea what was missed because of this. She did however give me her number to call her in the morning if it had not resolved - by the time I finished talking to her exchanging info and cooled off (about 15 minutes later) the problem resolved itself and I am back up.
    & now if you will excuse me I now have an outgoing issue to address (errr!)... I will leave with this clue however - I was told that if you are not having success with any devices but are able to at least log-on at iCloud-online, even if you still can't access email there (contacts/calendars appeared fine, just could get email to load), then its not you. You need to call support... or wait for it to clear on its own.

  • "Unable to Connect" error continually shows up despite having reinstalled firefox and troubleshooting. How do I get firefox to work properly again? (windows 7)

    I turned on my computer and before I could start firefox it said it was updating. When it said it had finished updating and there were no error messages indicating that the update had failed. When I opened firefox it pulled up the last tabs I had open before closing the program. None of the tabs functioned properly and gave me "unable to connect" errors even when I opened new tabs, no matter what the website was. Everything worked properly in internet explorer. I tried restarting my computer and firefox, troubleshooting, restoring firefox, uninstalling and then reinstalling firefox, checking my firewall and the problem persists. I've tried changing my proxy settings according the articles on the support page but nothing has worked. How should I fix this? Firefox is my favorite browser I would hate to give it up.

    see: [[Fix problems connecting to websites after updating Firefox|Fix problems connecting to websites after updating Firefox]]
    Also possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Is there a fix for Mail keeping 4 connections open for one.......?!

    Is there a fix for Mail keeping 4 connections open for one email account setup as IMAP.......?!
    Im just wondering whether this is possible because it means our company website falls over when the processes go over 25! There are a lot of emails.....
    It is a massive pain and ideally we dont want to upgrade our hosting package if we can help it!
    There must be a way round it?! Someone brainy know any tricks?!

    Ernie Stamper wrote:
    Never have encountered this -- more info, please? What are 4 connections, exactly?
    Very simple: Mail opens one connection for each IMAP mailbox on the account. Typically, this means Inbox, Sent Mail, Drafts, and Trash, but also includes Apple Mail To Do and Junk and any mailboxes/folders the user has created.
    The problem is that Mail is keeping these connections open when it's done checking for new mail, even when *Use IDLE command if server supports it* is not enabled. With 4 email accounts on one server, this causes a "500 Internal Server Error" because there are too many processes running. As soon as I quit Mail, my web server resumes serving pages.

  • How to fix slow mail in mountain lion in a easy way

    How to fix slow mail in mountain lion in a easy way

    Please follow these directions to delete the Mail "sandbox" folder.
    Back up all data.
    Triple-click the line below to select it:
    ~/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 selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
    Quit and relaunch Mail, and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
    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.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

  • Unable to Connect error 948 via SQL

    System Center 2012 DPM trying to connect to a SQL instance on a different server using Windows Authentication. Getting the unable to connect error "Unable to cnnect to xxx.domain.com (ID: 948) Verify that the DPM service is running on this computer",
    I figured out that if you add the user to "sysadmin" in SQL management it works for that user.  My question is, is this the best practices method of solving this problem?  Will this need to be done for every windows user
    that tries to access the DPM, or is there a more proper way?

  • How do I fix Maverick Mail printing smaller font?

    I just upgraded to a new MacBook Pro with Retina screen running Mavericks 10.9.1. Restored my stuff from Time Machine Backup of my old MacBook.
    I discovered that Maverick Mail is printing all emails in smaller size than what they are written. 12 point Helvita looks like 8 point, or less, when printed from the Maverick Mail on a laser printer, also connected to my wife's iMac. Printing the same emails from the iMac, running Lion, prints in accurate 12 point size. I have printed other documents from my Mavericks MacBook, i.e. PDF's that I created on the old MacBook. Those documents print in original size. So, problem is with Maverick Mail.
    For some reason, Mail is reducing the print size of the emails, no matter if the email is going to the printer or printed to a PDF file. The font size is reduced.
    I have seen that others have had a similar problem with Maverick Mail.
    Has anyone found a fix? Or do we have to wait for the Apple geniuses to get around to findiing their mistakes in Mail?

    Keep the Powerbutton and the Homebutton pressed at the same time until you see the Apple logo on your screen.

  • URGENT: Apps: Scan to e-mail: Unable to connect to server (HP6600 Officejet)

    Gd day,
    Bought myself a new HP 6600 Officejet.
    First 4 months worked fine.
    Since the last two weeks i am unable to use the scan to mail app.
    I can go through all the menu's
    apps => scan to mail => pick my emailadres = > scan.
    But then troubles start and i receive an error message as below.
    Printer cannot connect to server. Pls check connection and try again.
    i've tried as good as everything,
    Hard reset of the printer, firmware update,  deleted my internetconnection and reconfigured it, but nothing helps.
    Pls help me on this matter since I loose a lot of time with scanning to my computer and then mailing to my mailbox on windows (CITRIX remote loging) 

    Hello Yelle92,
    Welcome to the HP Support Forums. I see that you are getting a connection error message when trying to use the scan to email feature of your Officejet 6600 printer.
    There are several steps I would like you to try please. 
    Please turn off your printer. 
    Please turn off your router.  If your router doesn’t have an on/off switch, please unplug the power cord from the router.
    After waiting a full 60 seconds please turn on your router (or plug it back in). 
    After the router has completed its startup routine please turn on your printer.
    After the printer has completed its startup routine, please test the scan to email feature.  If it works there no need to continue with any further trouble shooting steps.
    Please set a manual IP address and manual DNS servers for the printer. I have included a link to another post with the steps, including screen shots on how to do this.   Don’t worry that the screen shots show an Officejet 8600 printer, the steps are the same.
    Please test the scan to email feature.  If it works there is no need to continue with any further trouble shooting steps.
    Please call HP’s Cloud Services at 1-855-785-2777 if you live in the USA/Canada region. If you live outside the USA/Canada region please click here to find the Technical Support number for your country/region.

  • Mail: unable to connect to my SMPT server? Also new Mail Account defaults to iMap and won't let me change to Pop?

    Dear All,
    I've been with the same UK internet and email provider for years and they've given me solid and reliable service. I've worked my way through the Apple Knowledgebase checklist and tests and proved that my isp/esp is working normally so the problem has to be with Mail.
    I fiddled about trying to create a Mail Account on my late 2011 but-new-to-me MacBook Pro a couple of days ago and, it might be completely unrelated and simply a coincidence, but since then none of my devices, Iphone 4S, Powerbook G4, iPhone 3G, the MBPro can send email using Mail.
    Whenever I try I get prompted for my password but when I enter it says it's wrong but it definitely isn't because I even changed it this morning through my isp/esp and it worked and I then changed it back again to my correct password and it works also to get into webmail that is, not via Mail.
    When I run Mail\Window\Connection Doctor and check the status it shows Mail is unable to connect to server but that it can connect to the internet. I get the following message: Trying to log in to SMPT account failed.  Try to verify that username and password are correct.
    Now, whenever I try to create a new email account on MacBook Pro Mail keeps defaulting to iMap and wont let me change it to Pop which is what I need.
    Does anyone have any ideas?

    Dear All,
    I'll finish off this thread in case it's of use to anyone else in the future.
    I couldn't get the email pop account to recognise my sign-in even though I've been using it continually and without problem for the last several years. It's always been BT and Yahoo so it's more likely to be the fiddle about I did on my temporary, pre migration user account that caused the hiccup.
    In th end I had to create another pop account which I was able to once I'd migrated my settings from my PB G4 to the MB Pro.  Unfortunately this didn't merge the numerous email folders that I'd created previously in Mail but I still have them on the PB and I believe they can be transferred manually which is what I will do.
    Thanks for everyone that took the time to help.

  • How to fix the windows and nano connection

    I recieved my ipod nano and for 2 glorious days it worked. Then my pc could no longer detect it, it just said "malfunctioned usb device" and didnot appear in itunes. The Nano just has the menu as opposed to the "DO NOT DISCONNECT" screen
    After a long and arduous day i managed to fix the problem.
    By clicking on this link http://docs.info.apple.com/article.html?artnum=93651 it tells you how to fix it.
    i just did this - (with the ipod connected to the pc)
    1) turn hold on, and then off,
    2)then press menu and the center select button simultaiously for 6 seconds
    3)the apple logo appears
    4)then it goes back to the menu briefly, and then goes to the "DO NOT DISCONNECT" screen
    5)open itunes, wait a minute and your nano will appear
    Wahooooo!
    hope this helps everyone!
    Ben

    Weird.
    Yeah, that seems to work.
    I learned this after I railed about how defective the nonos were in the Apple groups.
    Oops.
    This seems to happen when the PC shuts down (as we told it it should re: power options) AND the nano is still plugged in.
    I'm not cool enough to say: "My bad", but it was certainly my error.
    I think that's what happened; I could be wrong

  • After mavericks upgrade unable to connect to printer

    After mavericks upgrade on one of my two 2013 iMac, when I try to print anything on my network printer and plotter I always obtain this message: "unable to connect to printer" than printer pause and got "pronto per la stampa" (ready to print in italian).
    I have a EPSON STYLUS PHOTO 1290 A3 color inkjet printer and an HP designjet 500 plus 24 plotter connected to a Windows XP machine under a Windows XP network.
    Trying to print from the seconf 2013 iMac with OS X 10.8 (NON OS X 10.9 Maverocks upgraded) everything goes as usual ant printer works well as from other two Windows XP machine on the same Windows network.
    Then apparently the "unable to connect to printer" problem is up to OS X 10.9
    Any suggestion?

    THis helped me. Had to share this!
    Go to this link: http://macs.about.com/od/printersharing/ss/Printer-Sharing-Share-Your-Windows-7- Printer-With-Your-Mac_5.htm
    Things to Keep in mind and setup first if your Server which your printer is connected to is a Mac Desktop like mine, otherwise the above instructions will not work:
    1) Make sure to have firewall set either to "Off", but if "On" then make sure set to allow SMB, Printer Share, and other devices. Thats a Biggie! (I suggest you Test first that you're indeed able to connect first to your Mac desktop server using the smb://YourServersFileSharingAddess.local, or cifs://YourServersFileSharingAddess.local. If you're not able to connect to your servers hard drive from your Laptop, then the printer setup will not work! So resolve this first and make sure you can connect using the mentioned protocols.
    2) When you see that you're able to connect, then go to your printer setup and follow the above links suggestion. Just make sure that when you enter the ip address which it suggest, that its the same ip or location name of your mac server which your trying to connect to, ie... (YourServersFileSharingAddess.local/NameOfPrinterConnectedToServer). Keep in mind that it is case sensitive and that if you have spaced in the name of the printer, its better and easier to just rename it and cut it down to just one name...no spaces! But if you must have the spaces, then use %20 to fill those spaces, ie... "My Printer name" change to "My%20Printer%20name".
    Then watch the magic!

  • Mail unable to connect to Exchange account in Macbook

    I have an Exchange Account for my work email and calendar. I recently had to change the password and as I updated the login information in my iPhone (IOS 7) and Macbook (OSX) I have found that the Mail app in the iPhone connects to the Account just fine... The Mail app in my macbook however is unable to connect (using the exact same login information).
    The password has many special characters, could this be the issue?

    Hey Oscar,
    Thanks for the question. I understand that you are experiencing issues with your Mail account in OS X. The following resource provides some great troubleshooting information. You can also try deleting and re-adding the account from System Preferences or Mail Preferences:

    Not really. It might be one of their occasionaly server outages, but as the process you've just been through should have set Mail up correctly it's difficult to see what else you can do.
    Unforuntunately if you want to contact Support about this it's not free - if you currently happen to have AppleCare, either because you recently bought Apple hardware or have paid to extend the inititial period, you can contact them here:
    http://www.apple.com/support/icloud/contact/
    You will need the serial number of the covered hardware.
    If you are not covered by AppleCare, then - in common with other free email services - there is no free support (MobileMe Support is no longer available) and you will probably be asked to pay a fee.

Maybe you are looking for
