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

Mail no longer functions with Exchange server update

Yesterday, the IS dept. where I work applied some updates to the MS Exchange mail server and now Mail will no longer retrieve my email from the server. I can send email, but not receive. The mail shows up in my queue, but never reaches Mail's inbox. Has anyone encountered a similar problem and if so, do you know why this might be happening? What did you do to fix it?
Currently, their solution is to switch us to Entourage but, in my experience, that app is too buggy to act as a real solution to any problem. And unfortunately, our support people are very Windows-oriented and usually won't bother with Mac issues unless prodded or given a good hint as to where to look. Any pointers I could pass along would be helpful.

Here's my 2¢:
We (the Mac folks) ran into the same thing when CORP upgraded to Exchange 2003. IT decided they did not want to support alternative e-mail clients (Linux/Mac, or other), so they shut down port 143. In doing so, they forced us to use Entourage, or the web client.
I know that Mail has an 'exchange' server when setting up account, but it uses port 143.
Well, that my story...and I still really dislike Entourage.

Fascinate no longer connecting to Exchange server

After a year of flawless email through an Exchange server (required for work, switching is not an option), my Fascinate abruptly stopped communicating with the Exchange server. I have tried deleting and re-creating the account several times without success. After entering the required info about the server, name/password, SSL, etc., the phone tries to connect to the server and then displays "Setup could not finish. Cannot connect to server." Meanwhile, my laptop continues to use the same settings to connect to the Exchange server without difficulty. I'm wondering whether this was caused by the multiple recent updates from Verizon.

Turns out I was the victim of our company IT department. They decided to upgrade the Exchange servers, changed the server address in the process, and updated the address on all the computers through the network but didn't bother to tell smartphone users so we could update our devices. Apologies for wasting bandwidth.

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.

HT2480 Ipad mini - exchange email stopped working randomly Error: "Cannot get mail. The connection to the server failed."

I got an iPad mini over Christmas and have had no issues setting up/managing my email until yesterday. I've had my Exchange email working for almost a month, and yesterday I stopped getting emails and getting the error: "Cannot Get Mail. The connection to the server failed."
I tried resetting the device (multiple times) and deleting and recreating the Exchange account (multiple times). This is getting annoying because it worked fine up until yesterday. I'm not aware of any updates to the device, or any changes that have occurred since yesterday.

Due to a screen issue, I had my iPhone 5 replaced two days ago. I repeated deleted the mail account and kept adding it but this did not make any difference. When I attempted to setup the new phone with my Google (Gmail via exchange active sync) accounts I was receiving this same "Cannot Get Mail" error. From what I was able to gather, this problem should be affecting Gmail accounts set up via Exchange. When originally purchasing the phone I was assisted and directed to set up my Gmail account through Exchange because it had the ability to use "ActiveSync" and push not only mail and calendars, but all of my contacts as well. I found this article regarding the subject.
http://www.pcmag.com/article2/0,2817,2413283,00.asp
What it came down to was having to delete my Gmail via Exchange account and separate it into two different accounts, a regular gmail account for my mail and a CardDAV account for my contacts.
Here is what I did. Google is changing their system and for new registrars Exchange ActiveSync will not work so you will be unable to register your account via Exchange and have your mail, calenders, and contacts all pushed together. I find this change really annoying. If you are having problems accessing your contacts after deleting the mail account, like I was, here is the work around.
To circumvent this issue go to Setting > Mail, Contacts, Calendars > Add Account > Other > Add CardDAV Account: Under server ender google.com, then your email user name and password, then click next to verify the information.
I hope this helps.

Can java mail be used for distributed exchange server?

H,
I am trying to connect to MS Exchange Server to read my mails using Java Mail API.
I have a questions about using it with Exchange server.
We have 6-7 exchange servers in our company and different users have mailboxes on different servers. My internet mail application will be used by everybody in the company.
But while connecting to exchange server using java mail I can only cnnnect to one server and port. What happens when user mailbox is not on that server. How can I use javamail in this scenario where user mailboxes are on separate servers??
Thanks

You said that you can connect to Exchange server my you help me with this because i cant connect to Exchange server, mayby you can post me a code example? 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 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.

Hi,
The connection in Outlook 2011 for Mac is difference from the Exchange connection in Outlook for Windows. The Outlook for Mac is using EWS for Exchange connection.
According to your original posting, there seems to be some issue with your autodiscover service. And some Exchange services (such as OAB, OOF, OWA etc.) are using webmail-01.xx.com namespace in the URL. Please double confirm the configuration in your Exchange
server.
Additionally, please check the autodiscover service on Outlook for Windows machine. If all configurations in server side are correct but the issue persists, I suggest we can ask a question in Outlook 2011 for Mac forum for more help:

IPad cannot connect to exchange server

I keep getting an error message when I try to retrieve email from my exchange account.
Cannot get mail. The connection to the server failed.
My safari internet works perfectly. I have checked my mail settings and they seem to be correct. What are some steps that I should take to troubleshoot this issue? Is this most likely an issue on the mail server?
I was reading a post where the user stated their fix was: "The fix was that my IT department had to explicitly add my iPad serial number as an authorized device against my exchange account."
Is this something that has to be done? How would I go about adding my iPad serial number as an authorized device against my exchange account? Exchange ActiveSync?
Any and all information would be helpful.
Thanks,
Andy

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.

HT6147 After the upgrade to 7.0.6, all my mail boxes get errors saying Cannot Get Mail. The connection to the server failed.

Please help.

I'm encountering the very same issue. I updated to 7.0.6 and now I continuously get the 'Cannot get mail. The connection to the server failed'.
I'm on an iPhone 5 and my email account is Outlook.com set up through the Exchange option.
I have attempted PhilipRoy's suggestion, but unfortunately it hasn't solved my issue. Please note that this happens both on WiFi and 3G.
It's driving me nuts.

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.

Can no longer connect to remote server via VPN

I recently installed OS 10.5.8, and have found that I can no longer connect to my server at work. The VPN itself (via PPTP) works fine, it's just that when I try to connect to the remote server (via Connect to Server) I get a dialogue saying 'A volume failed to mount.' A further dialogue says 'Sorry, the operation could not be completed because an unexpected error occurred. (Error code -6602)'
Has anyone found a way around this, please? I'm disabled and I need to be able to work from home – without the connection I'm stuffed! Obviously I've tried rebooting the machine etc, but nothing seems to help.
Thank you for any assistance you can give.
Kitty.

For some random reason this connection has begun working again – please ignore the question!

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.
