Mail refuses to connect to my Exchange Server

I have an Exchange Server which also functions as an IMAP server. I cannot get mail to connect this server using the IMAP protocol. Thunderbird on the same machine connects to this exchange server just fine using IMAP. And Mail does not have problem connecting to other IMAP servers. Any idea on where I can look to troubleshoot?

I'm in the same boat and have been banging my head against this all day. Have you found an answer yet?

Mail refusing to connect

Since yesterday my Mail refused to connect to my Exchange 2007 account.
It all worked fine until then.
I also have Outlook on Mac, and it refuses to connect.
I didn't change any settings since then and the firewall is off.
On the same machine I also have Windows in Bootcamp, and Outlook in Windows.
That one connects.
Does anyone have a clue about what's happening here?

Can anybody help? The account seems fine.
I can add it through IMAP, but there's something about Exchange 2007 that is not working.
Any tips about troubleshooting would be appreciated.

Hi - for some reason, my IPAD3 mail client has decided it can no longer connect to my Exchange server.

Hi - for some reason, my IPAD3 mail client has decided it can no longer connect to my Exchange server. It's worked like a charm for weeks. Any thoughts?
For the record, I've got a POP mail account that is working fine on the machine and the WIFI is up and running (Safari is loading fine).
Thanks

Hi Jim,
Your issue is the most FAQ in the forums, it is an ongoing problem with Tiger waiting to be fixed by Apple. Till then, forget your aliases and use either Command-K or from the Finder Go-->Connect to Server and enter the remote Mac's IP address to connect.
Also, Open Utilities-->Terminal and type lookupd -flushcache (Press Return) and reboot. Do this for both macs.

Why do I get the message "cannot get mail" when trying to connect to microsoft exchange server.

Why do I get the message "cannot get mail" when trying to connect to ms exchange server?

Hard to say. Has it ever worked? Maybe your account has mobile e-mail disabled. Maybe ActiveSync isn't set up properly on the server. maybe the correct ports are not open on the corporate firewall.
You will have to talk to your IT department.

Mac computers in the office are not able to connect to our exchange server.

We started facing this problem about a month ago in our office where the apple computers can not connect to the exchange server via outlook or applemail or anything for that matter. All the other computers can connect to the exchange server with no problems
and the apple computers can even access the exchange server via OWA but the outlook and applemail apps would not connect to exchange. We have tried even deleting and re-creating some accounts on the apps but they still would not connect. At this point I am
at a complete loss and I looked everywhere through google to find out if anyone else has faced this problem but to no avail.
A little background information. This specific problem started happening after there was an un-expected series of power outages to the servers and they were shut down un-expectedly. I personally restored the servers and turned on all the services and made
sure everything was up and running after the power outages and everything was working fine. Also the first instance of the problem with the mac computers only happened two days after the servers were back up and running again and they had no issues in those
two days.
Right now we do not have that many mac users in our offices (only 3-4 users) and I have instructed them to use the OWA in the meanwhile but it is however an inconvenience to them. By now you may have realized that I am not a very experienced server admin
and I would really really appreciate any help. I extend my thanks in advance for any insight.

Hi Martin,
Thanks for the reply.
Right now I have Apple mail and Outlook installed on my mac laptop and both the applications do not connect to the exchange server. Apple Mail simply does a long process when I give my credentials to create my account and then it gives an error saying it
could not find the server while outlook quickly tells me that either the username or password is incorrect. At the same time I can connect to the server through outlook on my windows computer without any problems whatsoever.
From your reply, I gather that the VIA headers only affect Apple mail and should not affect Outlook app on the mac but right now, neither apps are connecting to the exchange server.
Either way I am trying to find out how to remove the VIA headers because it does not seem that we are using Kemp on the exchange server. Right now I do not have the in depth knowledge that I need because I was not involved in the implementation of our server
system, that was taken care of by a service provider and I was put in charge of mostly simple admin work. Now we are out of contract with the service provider so pretty much everything has fallen onto my shoulders.
If possible, would you mind pointing me in the right direction to finding out if I am using a L7 load balancer and how I would go about removing the VIA headers?

Unable to connect to MS Exchange server on ipad4 after upgrade to iOS 7.1.2

I received a new iPad 4 through work. Upgraded to iOS 7.1.2, but now I'm not able to connect to the Exchange server. Contacted IT through work, they have no idea how to correct it. They say all of my settings are fine. The error message says "Cannot Get Mail The connection to the server failed." Any thoughts?

Hello harrisk927,
It may help to remove and readd the account on your device.
Tap Settings > Mail, Contacts, Calendars.
Tap the affected email account.
Tap Delete Account.

Can't connect to the exchange server

I'm having trouble geting Mail to work with the exchange server here at work. any ideas?

I tried Mick's suggestions but they don't help. One problem seems to be that my boxname on the exchange server unfortunately has a space in it ("firstname lastname", windows style). Upon initial setup the configurator won't allow this, but even if I set up a dummy username (without spaces) and then add the space into the account information afterward, I still see "could not connect to this exchange server" when I click on "Check Again" in the Mail Connection Doctor.
The outgoing SMTP server is configured as servername.companyname.local, port 25, no SSL, and no authentication, and outgoing mail works fine... so it's not a routing or DNS lookup issue on the local side.
The other annoying thing is that the instructions at
http://docs.info.apple.com/article.html?path=Mail/2.0/en/ml1098.html
say that the "Assist me..." button should bring up something called Network Diagnostics. But that button is always greyed out, and spotlight doesn't turn up any apps by that name anywhere on the system.
Can anyone suggest a way of troubleshooting just where things are breaking down? I looked at the most obvious console logs and didn't see anything.
Thanks in advance!

Email Apps that let you connect to MS Exchange Server?

I finally convinced my boss to let me get a Mac Pro! I should be getting it next week sometime. Anyway, the 100 or so other people in the office all use windows & outlook (connecting to an Exchange server).
What apps can I use to connect to Exchange? I need to be able to view shared calendars etc...
Thanks in advance!
Home: Mac Pro / Macbook Pro / iMac
Office: Coming Soon a Mac Pro

What if i just need to access Public calendars?
If needed I can always forward my exchange mail over to a POP3 acct. At which point I would only have to worry about the calendars

Get Mail to Stop Downloading Junk from Exchange Server

Our company uses Comcast Business Class for email service. They in turn are running Exchange 2007 servers.
I recently had to reconfigure all my email accounts do to a corrupt Mail plist. Upon doing so, I found out about Mail 4.2's (Snow Leopard edition) ability to auto discover Exchange server configurations. Pretty nifty. With one caveat. Apple Mail is downloading all the Junk mail that winds up on the Exchange server. Which is quite a bit.
Originally, before the corrupt plist problem, my Mail 4.2 was upgraded from Leopard and the account information transferred using the non-auto discovery method, if you will. When it was setup that way, there were only about two or three Junk messages that breached the barrier per day. Now I'm getting dozens.
On to my question: is there a way to configure Mail to stop downloading Junk mail from an Exchange server and just leave the Junk on the Exchange server?

Thanks, William.
They are, fortunately, being filtered into my Junk folder in Mail. There is the occasional culprit who sneaks through to my Inbox, but most wind up where they should. It's just the increase in volume to that Junk folder that has me concerned.
Additionally, if a non-Junk message gets erroneously tagged, I no longer have the option I once had to set the message as "This is not Junk". That used to appear as a graphic and button at the top of the message. It seems like I no longer have that capability.

Need free OST viewer tool to help to view OST files without connecting to MS Exchange Server and MS Outlook.

Need free OST viewer tool to help to view OST files without connecting to MS Exchange Server and MS Outlook.

Hi Howard,
As I know, Microsoft does not provide any kind of inbuilt tool or free software to only view OST file, even without the connectivity with exchange server (Offline).
Try SysTools OST Viewer freeware which helps you to view all OST file save at your system in an easy way, whether you want to see the attachments or other items of OST file.
Note: This is a free inbuilt utility, but try it on your own risk as I am not much aware about it and its working. But this tool sounds good according to your requirement and hopefully it would give you 100% satisfaction.
Thanks

Hi,
The "<cfexchangeConnection>" tag supports both "HTTP"

Also try removing the

i didn't have any success to fix mail flow, any solution?

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.

Connecting to MS Exchange server

We are going to implement outlook functionality in our project. So that, we are trying to connect Microsoft Exchange server.
Sofar, I found the some information reg this thing from google.
Before connecting MS Exchange server, first I have to connect LDAP server using JNDI API.
Is any Java API provided for connecting to MS Exchange server from LDAP. If is there, How can I connect to MS Exchange server using J2EE application from LDAP?

No, not from JNDI.
You can manage Exchange Server via CDOEXM.
Details on CDOEXM can be found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/e2k3/e2k3/_esdk_reference_cdoex.asp
Not being a Java developer, I don't know how you invoke COM objects from Java.

Whats wrong with my code?
Please help!!!!

You're using the "imaps" protocol, but you've set properties for the "imap" protocol. Change all the property names from mail.imap.* to mail.imaps.*.
Also, get rid of all the socket factory properties.
If you still can't connect, see these connection debugging tips.
Most likely you're using the wrong host name or port number. In almost all cases, it's better to just let JavaMail choose the correct port number.
