Connection to Exchange Server Suddenly Failed!!!!!!!

I have had my iPhone for about 3 months with no issues syncing to my work email, contacts or calendar. Suddenly this AM it will not longer sync and I receive this message: "connection to server failed".
I've tried to delete emails from my inbox, reboot my iphone and delete/re-establish my mail account.
Anyone have any otyher suggestions?
Thanks

That is bad news, your Exchange server is not responding, it may be down, or the problem could be at your end. Do you have web access to the Exchange server, there normally is a URL to go to in order to access mail.
It may be (no guarantee here)
mail.rpc.connect.kent.ac.uk/exchange, or mail.rpc.connect.kent.ac.uk/owa, try them both.

Establishing connection to SQL server suddenly failed

Hi,
I had a working SQL connection before, but today i've tried to connect and got this message:
TITLE: Connect to Server
Cannot connect to User-PC\SQLEXPRESS.
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:

p.s. I'm novice to SQL ssms.
with regards,

1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

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.

Winnie Liang

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 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.

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.

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,

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

Connection to [i]server[/i] failed (Error NT_STATUS_IO_TIMEOUT)

I have no windows machines so it's only my laptop and desktop both running linux that I need to connect to this. I have tried googling and searching these forums to no avail
Thanks for any help that can be offered
Mike

If I run the following (on the machine I'm trying to set up the share)
smbclient -L localhost -U%
I got the following output
Connection to localhost failed (Error NT_STATUS_CONNECTION_REFUSED)
so I thought it might be something incorrect with the iptables side of things, however I haven't really touched that at all and it seems to look correct
iptables -nvL
Chain INPUT (policy ACCEPT 667 packets, 79977 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 157 packets, 20724 bytes)
pkts bytes target prot opt in out source destination
So from my (very little) knowledge this appears correct (I think)... However it appears that something is blocking access somewhere.

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.

Help My Iphone 3GS the hotmail has stopped working and my contacts and the calendar no longer hook up to it it keeps saying the connection to the server has failed and it running the latest 5ios

Hi please help I have an Iphone 3 G S it is using the 5.1.1 ios upgrade which it has had for sometime although there was a minor update last evening ? My phone worked fine until arround 1 pm today then it stopped getting mail from my hotmail account along with the hotmail I am not longer able to see any updates to my calendar and most of my contacts have dissapeared. I have tried reconfiguring the hotmail account, deleating it, and putting it back on, and changing the password but none of these has worked. I know hotmail is working from my computer and it also working from another app I downloaded to the phone just now ( mail pro) but it still says connection to the server has failed?
Thanks so much

Click on your Hotmail account in Settings, click on the blue arrow and Forget this Network and try signing in again.

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,
This JCO Exception caused by network problems, connection breakdowns, gateway problems, unavailability of the remote SAP system, etc.
What you can do is: Get the host of the SAP System from dev_jrfc.trc or the JRFC trace; ping the SAP system from command line; check routers, gateways, SAP systems
If an error has occurred on a lower communication layer, for example an RFC_ERROR_COMMUNICATION or RFC_ERROR_SYSTEM_FAILURE exception, have a look at the dev_jrfc.trc files. These files are written by JRFC and can be found in the directories j2ee/cluster/server* of the J2EE Application Server Installation.

NW2004s Connect to Message Server Host Failed - BW to Portals connection

Hi,
I am trying to connect a SAP BW NW2004s Patch 8 system to a NW2004s Portal. All of the checks in RSPOR_SETUP are successful.
However when I try to launch a query from Bex Query it fails with the following message.
"Connect to message server host failedConnect_PM TYPE=B MSHOST=SAPMSCR6 GROUP=webshop1_biw R3NAME=CR6 MSSERV=01 PCS=1"
The message server entry in the System Landscape object for the BW Server is "SAPMSCR6". Is this right?
I have searched for information about this and can't find anything. I am sure it is something basic. As anyone else resolved this issue or do they have an idea what might be causing the problem?
Any suggestions gratefully received.
Dave

I get same error message when i test the JCo Metadata connection, Model data connection works fine.
The message server value under WebDynpro content admin is created with right values as i checked with Basis person.
My service file in C:/windows/system32/drivers/etc has entries for both J2EE stack entry and ABAP stack (on remote server) entry with port numbers.
When i ping the ABAP (remote server) from my machine command prompt I get response.
I am running out of options. I really appreciate your inputs.

Hi, I think this might have todo with the fact that your Java stack wants to connect with a server from the same logon group called "PUBLIC".
Please make sure you added the same logon group "PUBLIC" to the ABAP Server. Try transaction SMLG.
Also as posted above the SLD needs this info aswell.
After using the transaction SMLG, log in and out 5 times in a row to your ABAP stack using SAP GUI. This might actually force an update to the SLD.
Greetings,
Robbert

Connect to message server host failed;WSAECONNREFUSED: Connection refused

Hi All,
I am getting the following error when I tried to test the system connectivity from the portal to NSP instance.
Connection failed. Make sure that Single Sign-On is configured correctly
I found the following entry in the logs
Error> occured >Wed Feb 03 22:43:49,875<

Both NSP and J2E instances are on the same server. OS - win2k3.
I checked the services file and have the sapmsNSP entry.
I am able to launch an SAP transaction from System Administration -> Support
RZ70 from NSP also fails JCo error. SLD_UC RFC itself works fine and the JCo RFC provider SLD_UC program is running
WEB AS & ITS connections work fine.
User authentication is from backend, NSP.
I think I have gone thru all the logs but could not resolve the issue.
I appreciate any help on this,
Victor

I tried to go thru the thread. I did not find any clue as why only server connectivity is failing. ABAP trial version is running fine and the NW trial version is working fine too. These run without crashing. I did a lot of customizing on the portal but dont see any issues except the System Connectivity. Like I mentioned I did UME configuration to point to NSP ABAP instance and I can log into the portal with user credentials that I use to login to ABAP. I can launch webgui etc without any issues.
