Mail.app suddenly lost connection to exchange server

Hello
I have 3 (at least) different mail.app accounts (on different macs) that have lost the connection to our exchange server and is not able to reconnect to it..
We can access the mails from webmail or from Entourage.
At first we thought that it was the latest update to mail.app but we have found others on the internet with the same problem (before the update). Sadly they have not provided us with the sollution to the problem.
I plan to re-boot the exchange server on sunday and will update the post with the result.
But if anybody have had the same problem and found a solution, then I would very much like to hear about it.

I'm having the exact same issue. However, since I'm not in the IT department I cannot reboot our Exchange server. Were you able to find a solution?

  • Mail constantly crashing while connected to Exchange Server 2007

    A few of us at my workplace got 10.6 when it released because we were so excited about the native Exchange 2007 support. The problem that I have been having is that Mail constantly crashes at (seemingly) random times, even when I'm not actively using the application. I also loaded 10.6 onto my MBP but I don't think it has ever crashed while using Mail on the same Exchange account (inside or outside of the office).
    One other co-worker occasionally has Mail crash but he said maybe once per day. Mine is at least 5-6 times per day. Set up of the accounts has been flawless but the constant crashing is a pain.
    Anyone have any ideas why this might be happening or how to fix it?

    Try this - find the /Library/Preferences folder in your user/Home folder and then locate and delete this file:
    com.apple.mail.plist
    *Caution* - doing this may clear your account settings so be sure to note those first in the event you are required to reconfigure, etc.

  • Writing client app to connect to Exchange Server 2013 and set OOF for users on vacation

    I am coding an C# app that should connect to Exchange Server 2013 on-premise (Servers Location is not in our Company). I`ve got an account (User and Pass) with readonly admin-rights for now and want to read and set OutOfOffice Objects for other users. I
    decide to use EWS Managed API over Autodiscovery but I am bit confuse how
    I tried to connect with "service.UseDefaultCredentials = true" and read contacts -> this code works:
    try
                ExchangeService _service
    = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
                _service.Credentials
    = new WebCredentials("service.exchange",
    "1234", "domain");
                _service.TraceEnabled
    = true;
                _service.TraceFlags
    = TraceFlags.All; _service.UseDefaultCredentials
    = true;
                _service.AutodiscoverUrl("[email protected]",
    RedirectionUrlValidationCallback);
                foreach
    (Contact contact in _service.FindItems(WellKnownFolderName.Contacts,
    new ItemView(2)))
    var test = contact;
            catch
    (Exception exception)
                Console.WriteLine(exception);
    After that I tried the same with _service.UseDefaultCredentials = false; got error -> "The Autodiscover service couldn't be located." I am not shure if this "direct log on" is the right way, On msdn I've read about "delegate access"
    and "Impersonation" (NTLM and Basic Authentication) I'am a bit confused. Can anybody help me?

    hi,
    when you set a credential, you don't have to set the UseDefaultCredentials property (it is already updated).
    For autodiscover, you should try to set the property EnableScpLookup to True if you are in the Exchange domain or it is known by the current domain.
    Autodiscover uses a domain query (through Active Directory) and/or a dns query (this requires a DNS register for autodiscover.domain.net) to determine the access to the autodiscover service URI.

  • My iphone has lost connection to the server; I cannot get e-mails.

    My iphone has lost connection to the server; I cannot get e-mails. What can I do to fix that?

    I recently put on a PowerPoint presentation at DU, in Denver Colorado; signed on as DU guest to access Internet link.  SInce then I haven't been able to get e-mail on my Iphone - Cannot Get Mail, Server Stopped Responding.  I tried all previous suggestions, such as rebooting phone, updating software etc.  I went to MacBook Pro and tried logging on to yahoo e-mail.  Apparently there was a security risk to my e-mail account so Yahoo locked up my account.  I reset my password, it was verified through text message, and Voila it worked.  Don't forget you also have to change this on your Iphone: go into settings; Mail, Contacts, Calendars; click on your e-mail browser, then account and enter your new password, click done and it will verify on you phone as well.  Hope this helps!!!

  • Mail no longer connects to Exchange Server

    Hi,
    I recently upgraded from 10.4 to 10.5.
    After the update everything was working fine, including Mail. It was talking to my Exchange server as it should.
    But I had to dabble. While I was previously connecting using IMAP I noticed the Exchange server option in Mail so I decided to give it a go thinking it might enable some more of Exchange's features.
    However, Mail will not connect to the Exchange server. Even trying to switch back to IMAP doesn't work. It just won't connect.
    I KNOW the settings are correct and I have other machines here that are working fine (using the Exchange account option in Mail - I set them up last week, no problem).
    I have enabled logging in Mail and it appears that the Exchange server is refusing my username or password - both of which are certainly correct.
    Using identical settings (albeit with IMAP) in Thunderbird is no problem.
    Any ideas on this? It's driving me nuts and I really want to go back to using Mail rather than Thunderbird.
    Many thanks in advance.

    I have just replaced an ailing emac running 10.3.9 so to get all my emails transfered, i imported them . I had by this time set up my old accounts affresh .now the old ones fight with the new and try to change the out going smtp server settings I can recieve on all accounts but only send out on one and that is after one and a half days plus a trip back to the dealership-still not right .And somehow it insists on sending my other email accounts through only the one main server which sort of works but changes each time you log in. The computer no longer recognises email addresses sent from my old folders - a serious pain when you have to look up each and every address in old folders.
    When you go into the advanced settings the option none is not there but on one occassion all the options changed. Looking at this forum I think giving my emac the kiss of life might have been a better business proposition. As to your problem some info the guy at the store deleted in the key chain info. helped but not sure how he got there

  • SAP PI Connection Microsoft Exchange Server (Scenario Mail -- SAP PI -- File)

    Hi experts,
    we want to connect Microsoft Exchange Server to SAP PI. POP3 and IMAP4 is not allowed on mail server side.
    But the standard mail adapter in SAP PI  (configured as sender communication channel) only works with POP3 and IMAP4.
    Can anyone help me to solve this problem
    Thank you for your help.
    Mario

    Hi Priyadshini,
    The way that you have developed your java program can be different that the way that SAP did it. With pop3 in PI, as far as i know, it is no possible to change the read/delete properties that the mail server has by default, as Amit and Ilya mentioned you should try with the imap solution or to talk to the mail server administrators.
    Are you sure that the messages is being deleted?, have you checked other mail folders in the user account?, may be the message is being moved.
    Regards.

    Hi,
    According to your description, users cannot connect to Exchange server 2013 both internal and external.
    Please run Test E-mail AutoConfiguration in Outlook to check your autodiscover service. Also
    reset your Exchange virtual directory to connect correctly. If the issue still continues after all configurations are setting properly, collect some Event logs would be helpful.
    If there is any question, please post the results here for further analysis.
    Thanks,

  • Problem in connecting to exchange server

    I have generated a certificate as specified in the link http://www.dylanbeattie.net/docs/openssl_iis_ssl_howto.html. It generates an X.509 certificate. I installed this certificate on pop3 server on Microsoft exchange server. I also installed the certificate on client m/c. On client m/c, a Java application is running, which tries to read mails from exchange server using SSL. But this exception occurs when I run my java application:
    javax.mail.MessagingException: Connect failed;
    nested exception is:
    javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    at java.lang.Thread.run(Thread.java:595)
    It seems I am unable to connect to exchange server using this certificate. While I also tried a free trial certificate from thawte, that worked fine. Could u help resolving my problem?
    Thanks

    Peddard, you will have to be more specific on your settings. It's important to note that the iPhone's host name entry must resolve both internally and externally if it's going to work correctly. So, on your internal DNS server, you must make a mail entry with the same name as what you are publishing externally. In my case, mail.domainname.com is registered on our external DNS server with a public IP address. On the internal DNS server, mail.domainname.com registers to a 192.168.x.x address.
    However, you can find in another post that in my situation, the iPhone would not work correctly on our LAN. It worked everywhere else but the issue seems to be that when on the Edge network and the LAN, there is conflicting DNS resolution. This was intermittent and unreliable at best.
    Our workaround was to create a second network, simply wirelessly with a couple of Airport Extreme Base stations on a separate external IP address. Now, DNS resolved to the external address and it works like a charm. Not a fix, but a workaround.

    Hi Alireza
    The above tech-net http://social.technet.microsoft.com/wiki/contents/articles/24056.what-the-crash.aspx
    will be applicable only if we get these events in the app log 1019,1018,1036,4999
    You can check the transport service is running in which service account - Local or network 
    It should be running in network account by default.
    You can run get-transportagent and check if there are any transport agents installed 
    If you find them then disable all the transport agents that you have installed on the Exchange servers by running disable-transportagents
    Disable the antivirus if you have any installed.

    on my iphone I am getting a "Cannot Get Mail" prompt says " the connection to the server failed. My mail last updated 1-31-14(the last time it would retrieve  mail) Ive done the turn on and off thing,thanks

    i had this problem a couple times. Try:
    1) to restart your iPhone (turn off and then on)
    2) connect to a different network or use cellular (it may be a network problem)
    3) delete your mail account from Mail app, and then add it back in
    4) create an icloud backup of all your data, restore through iTunes and then restore from icloud
    hope this helps. cheers!

  • Battery loss after connecting microsoft exchange server

    I am using iphone 3gs. Suddenly I have started loosing my battery after the latest update on itunes. I loose the battery once I connect microsoft exchange server. If I delete the account then the battery stays normal.
    Please Help if anyone have any information on this issue.

    I dont think its a problem with your exchange account as it worked normally before I would try restoring your phone to see if it fixes if not and you are still under warranty take it into a apple store and have a genius look at it

    Adobe cloud has lost connection with the server, can't get adobe cloud to work so I can re-install photoshop to fix a corrupted DLL file.

    *Adding new items/removing orphans*
    Try iTunes Folder Watch or iTunes Library Updater. Folder Watch is much faster on the adding files front, can be set to run in the background and includes a useful exclusion feature, however it’s slow at removing orphans. iTLU is better for this although doing it manually after looking at a list of proposed removals generated by Folder Watch is probably faster still. iTLU can also be set to update iTunes when you've used 3rd party tools to change tag info.
    You may need to amend the list of file types these programs look for. My list includes:
    .mp3 .mp4 .m4a .m4b .m4p .m4v .mov .wav .aif .mid .ipa .ipg .ite .itlp .m4r .pdf
    Note the last 6 types may not be recognised as already being in the library so should either be omitted from the search or you can add (at least for Folder Watch) individual exclusions for files you know are already in your library.
