Iphone 5 loses connectivity to exchange server

I know this is pretty common with Exchange servers...any news/updates? I have heard it is impossible to drop back to a previous version of IOS...like 6.1...too bad!

Thanks James, however I have tried that numerous times. Even tried to restore the phone to factory settings however I am getting an error that prevents the restore. I'm starting to believe there is something wrong with the phone.

Outlook Mac Loses Connection to Exchange Server

Hi All,
I've had this problem pretty since deployment a couple of weeks ago, so I'm hoping some one can point me in the right direction. I'm running Exchange 2013 on a Server 2012 Standard box with the DC running on a different box, every thing up to date.
Mac clients running Outlook 2011 (14.4.2).
Periodically throughout the day, Outlook loses connection to Exchange server. After several minutes, it will connect back up, and seems to operate normally. During the down time, I am able to connect to OWA, and ActiveSync seems to work as well.
If I run the Remote Connectivity Analyzer while Outlook is responding, I get no errors and the "Connectivity Test Successful" message. However, if I run it while Outlook is NOT responding, I get the following:
Exchange Web Services synchronization, notification, availability, and Automatic Replies.
Not all tests of Exchange Web Services tasks completed.
Creating a temporary folder to perform synchronization tests.
Failed to create temporary folder for performing tests.
Exception details:

Elapsed Time: 100141 ms.
Nothing I've attempted to do so far as had any meaningful impact, and I am fairly new to Exchange.
Following the adice I've seen online so far, I've:
I've made sure the auto discover in DNS points to the Exchange server.
I've disable auto-discover on the client, manually adding accounts, tried using their FQDN, local IP, LAN IP.
I've made exceptions to the proxie on the client.
Just not sure where to look next? Appreciate any advice out there.
Thanks,
Michael

Hi,
Before we go further, I'd like to confirm if your Outlook clients can work well when your Outlook MAC clients come across the issue.
If the issue only happens on your Outlook MAC clients, we can check the IIS log and confirm if there is any error releted to EWS. And you can recreate your EWS virtual directory to have a test.
Thanks,

IPhone can connect to Exchange Server with incorrect password!

I have changed my Active Directory password, but have not entered the new password into the Exchange account settings on my iPhone. Nevertheless, my iPhone can still connect and get mail from Exchange. Thinking that perhaps it was because the iPhone was still working with a connection that had been established before I changed my password, I turned it off and turned it back on again -- and it connected and got new mail!

Don't blame the phone just yet.
The server is where the problem is..... The Exchange Server/IIS front end is the gatekeeper to your email. If the password is sent wrong, the server will reject you. Conversely, if your Exchange server is not authenticating at all, it will let anyone in.
What is probably happening is that your password has not synchronized from AD to Exchange. This is not unheard of, but if it persists you should let your Sys Admin know.
My guess is that you can log into your OWA (Web mail) with your old password as well.

Why can't I connect to Exchange Server 2003? I'm using OS Lion. My iphone connects, what am I doing wrong?

Why can't I connect to Exchange Server 2003? I'm using OS Lion. My iphone connects, what am I doing wrong?

the iPhone uses active sync. Desktop clients do not. Desktop clients use another exchange protocol (which i can't remember as i'm not a microsofty).
Just because you can access via active sync doesn't mean you can access it by other methods, and vice versa.

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 com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:106)
at javax.mail.Service.connect(Service.java:234)
at ci.cryopull.core.PullAction.execute(Unknown Source)
at ci.cryopull.core.PullAgent.run(Unknown Source)
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.

Using iPhone with a Microsoft Exchange Server

Hi
Is it possible to connect the iphone to a Microsoft Exchange Server to access your emails?
Thanks

Ryan Simmons,
Exchange's ActiveSync protocol which requires licensing a propietary protocol from Microsoft is what you are asking for.
IMAP is one additional port open, and can be encrypted with SSL. If they are concerned about an additional port open, VPN is an option. Then only when the VPN is active will the corporate email be available. The other argument that has been advanced on security is on Windows Mobile devices the server can ask for remote wipes of data from the phone. The iPhone only caches emails, and goes back to the server to download them again when you go to view them again. If you change the password for the account on the server, the same results occur - the email is not available on the device the next time that account is accessed from the iPhone.
This article contains an outline of the things needed on the server to support:

This article outlines the VPN protocols supported by the iPhone:

Can't connect to exchange server after 1/4/2011 am update - anyone else?

Woke up this am and phone is unable to connect to exchange server for email. Last email received was @4:35am. I've reentered my password to confirm and exchange is working fine on Desktop. Any suggestions?

I'm pretty sure that the combination is right. On my macs everything works fine. Is there another reason why the exchange server could reject the iPhone? Similar to the 3.1 problems with the hardware encryption?

Connect my Exchange server via Wifi and EA6500

Hello, I have a problem. Since I have installed my new router, a Linksys EA6500, I have many problems to connect to my Exchange Server, which is located in my house, via Wifi. I tried to synchronize my Iphone and my Samsung tablet but it won't work. Most of the times I get the message that the Exchange server cannot be connected. When I turn off my Wifi en connect via my mobile provider I have no problems. When I am on a third party wifi I also can connect my server. Seems my own wifi causes lots of problems. My old router, a Dlink dir655, never had this problems. Can anyone help me?

Make sure that you have replicated the settings of your old router to the settings of the new router and then try also to isolate this problem by using a laptop computer and check if it will work. The purpose of using a laptop is order for you to isolate if the problem is with the router’s firmware. Check if opening port 443 on your router will be able to fix this issue. You can also check the links below for further information about this concern.

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

Outlook connection to exchange server problem

We have a new domain and an existing exchange server. The problem is if i log in with a local computer account i can autodiscover and connect in cached mode to exchange no problem. If i then login with a domain user account the same computer (tried on other
workstations) will fail to auto discover, fail to connect to exchange even with manual settings. I cant find anything obvious in Group policy.
The server is setup with the latest 2013 Group policy templates with office 2013 templates
Users not logged in with the new AD server can connect to exchange
Users not logged into the domain can access exchange server
My feeling is its a local setting that is missing or needs to be changed in Group Policy but i am at a loss as to what it could be
I have disabled roaming profiles too and it makes no difference.
Any help would be greatly appreciated.
Steve

Hi,
Sorry for my delay. According to your description, I summarize your issue to the following points:
1. No problem when the user logs in Outlook with a local computer account in Cached mode.
2. Can’t connect to Exchange from an cache mode enabled Outlook 2013 client when using a domain user account on the same computer automatically or manually.
3. Can connect to Exchange from an online mode enabled Outlook 2013 client when using a domain user account on the same computer automatically or manually.
It is right? If I misunderstand, please feel free to point it out. Additionally, I noticed that the server is setup with the latest 2013 Group policy templates with office 2013 templates. Please confirm
if the Outlook cache mode is disabled by OTC or GPO. If there is following registry key applied on the machine:
Software\Microsoft\Office\15.0\Outlook\Cached Mode
Meanwhile, please try to install an Outlook 2013 with a fresh ISO file(Don’t use any template such as OCT template), see if the Cached mode Outlook can connect to Exchange server.
Waiting for your updates.

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.

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.

Outlook 2013 not connect with Exchange server 2013 in internal network

Hello All,
I Have two Exchange server 2013 in our environment. Both server install mailbox and CAS role. After configure exchange server 2013, Outlook 2013 not connect in internal network. I have configure outlook manually. i tried by using the suggestion from blog
but not work. Outlook show that Server cannot connect/ server name could not be resolved. in outlook setting i also put exchange proxy setting. In exchange admin center i have changed the OWA, OAB, Auto discover name. But still not work.
I know that outlook can be connect from external by using ssl certificate and publish outlook anywhere but i did my configure from internal network.
Can you please suggest as soon as possible.
Thanks,
Parvez

Hi,
Firstly, I’d like to explain, same with external users, internal users use Outlook Anywhere to connect with Exchange server and use Autodiscover get all settings.
Thus, let’s try the following resolutions:
1. run the following command: get-clientaccessservice |fl autodiscoverserviceinternaluri
2. check if the host name in the above URL is in the DNS server and there is a DNS entry about the host name points to the proper IP address.
3. Check if the above host name is in your certificate.
Thanks,
Angela

HI, I just bought an iPhone 4S. Although my iPad and other iPhone 3GS connect to our server (SBS2003) I cannot get through. It checks all items in the connection and then I get the message :Cannot get mail, the connection to the server failed."

I Tried everything, rebooting, reset all iPhone, etc. All Apple devices work perfectly expect mine. Please advise

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.
If none of the above suggestions work, look at this link.
