The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete - Cant add Outlook accounts
Hi have recently started getting the following error message when setting up new accounts with Outlook 2007:
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
Outlook then prompts me to enter the username and password, i do so and get message again. This happens on Windows XP Professional and Vista, i cannot setup any accounts for new machines.
Points to note are that OWA works fine, and previous users who are already setup work fine also. It seems to be limited to setting up new Outlook 2007 accounts.
It can find the username fine. It comes up with green ticks underr the Online Search for your server settings:
Establish Network connection
Search for firstname.lastname@example.org server settings
Long on to server ---------- then it fails with a big red cross at this point
Recently i did add a second mail server to the network but it was not configured to talk to the other main mail server which was handling all the functions of mail box, CAS, hub transport. I had installed all the same roles on the second server with a view to move it across and retire the old server, the second machine is a different machine name from the main mail server. In summay my servers are:
svr001 Server 2003 R2 Enterprise x64 domain controller
mail Server 2003 R2 Enterprise x64 non-domain controller with exchange 2007 SP1
mail001 Windows 2008 Enterprise x64 non-domain controller with exchange 2007 SP1
The main box "mail" has been fine until i recently introduced this new server "mail001" into the network.
I am really stuck now and would really appreciate any pointers or steps to debug the above.
Quick update i removed Exchange from the mail001 box. I then rebooted the DC, and then rebooted mail box. Then it started working again.
This is great in that it works, however i am a bit concerned about migrating my 2003 server box mail server to Windows Server 2008 in case i get the same problems again.
Indeed not sure if its 100% fixed i hope it doesnt come back. Any ideas as to why it would have stopped working?

I have the same problem but I'm running one mail server. This problem just started a couple days ago. No changes were made to any server except for adding a BSAdmin on the server so users can check email with their BlackBerry.
I tried a reboot for both servers and I'm still having the same problem.
Anyone know what could be the cause for this? And how to fix it.
I am having the same trouble. Nobody seems to know what to do. My wife and I have the same computer exactly (Windows XP) running Office 2007. We both connect to the same exchange server at the same company. I can no longer connect out of the blue and get the above error message and she is connecting just fine. I am unable to reestablish a connection to the exchange server. I've tried uninstalling Outlook and still am having a problem. Please let me know if anyone has found a solution.
I'm having the same problem and just spent an hour and a half with Microsoft Tech Support to hear him tell me it's not an Exchange issue but an Outlook issue... something I told them to begin with :-(
Outlook runs and I can get internet email but sharing my calendar and intra office email (i.e. all the Exchange Server actions) are not available to me.
I updated the service packs, etc on my xp systems, then it works.
the problem i am having is with terminal server. almost all the users work well, a few come up without being able to find the domain controller.
i know they are there because they can logon to the network in house, outside via rdp it dies.
I recently reinstalled a PC on my computer network with Vista and Outlool 2007 (I tried XP and Outlook 2003 as well) on got the same messages. I was able the import the registry key below from a Windows XP machine that had my configuration already installed and its now working perfectly.
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook
I noticed that a number of subkeys were missing from the fresh installation.

what made the most impact, as i was intermittently getting the domain controller could not be found, was to update the system bios and all hardware updates and drivers for the server itself (not microsoft stuff, manufacturer stuff) which made a big difference. so go to your hardware manufacturer and get the updates.
Another solution maybe to ensure that the System Attendant service is on the Exchange server is running. This apparently was the problem as confirmed by my System Engineer who was on vacation at the time I encountered my problems.

I had an issue where my exhanger server bacame unresponsive. I rebooted the box and started configuring outlook on an XP desktop.
I also received the message: The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete...
Thanks, Girgimel. I checked the services on my Exchange 2007 box and the Exchange System Attendant service did not start.
Once I started the manually, I was able to set up Outlook on the desktop.
I've had this a couple of times. Usually after I reboot my Exchange server. Check the primary Exchange server (in case you have more than one) and check Microsoft Exchange services. Look for Microsoft Exchange Attendant services. Although it is set for automatic it appears not to be runing. Simply start this service and your outlook should be able to communicate with the exchange servere again.

This apparently was the problem as confirmed by my System Engineer who was on vacation at the time I encountered my problems.The sytem attendant service was indeed not running. (Exchange 2007, outlook 2007 clients). OWA worked fine, but configuring an existing account was inpossible on a clean client install.

I had try in many ways but i found a best solution when you cannot add new account with outlook 2007.
First i uninstall outlook 2007 and reboot your computer and install outlook 2003
when install complete try to add new e-mail account with outlook 2003 it never pop-up like "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete " when you can adding e-mail account with 2003 try to re-install outlook 2007 by upgrade
One solution I found...don't know if this will work for you.
On the local box, I removed the MS Office update: KB972363 and then I was able to connect to the account to my Exchange Server.
Here's the description of this KB from microsoft: http://support.microsoft.com/default.aspx/kb/972363?p=1
at the bottom are "known issues".

Hey all i just did this and it worked for me.
I went into iis manager. Properties of the exchange web site> directory security > in the secure commuinications area at the bottom of that windows select edit. A new window will pop up. select require secure channel (ssl). bam! I can finally get my mail and my webmail.
Hope this helps someone.
If the new account also has a new windows profile the problem might be related to first time use of Microsoft office.
Open MS Word and if it prompts for a name and initial go ahead and input something, then close word.
Try creating the outlook profile again.
I believe this causes a hold up sometimes because MS Outlook uses MS word as it's text editor.
(I know I'm replying to a 2 year old thread but I think this info is helpful as some of the times it is the culprit and others find it an ongoing issue)

I was having exactly the same problem. Searched a lot, until I found this forum. We'd had a powercut in the morning, and for some reason a number of Automatic Exchange services hasn't started, Microsoft Excahnge System Attendant and Service Host being two of them. Once they had been started it fixed the problem.

Tengo el mismo problema reinicie el server y despues de eso en varios equipos de la empresa ya no se conecta el outlook, lo tengo instalado en 80 equipos, algunos estan fuera de dominio, pero la falla es general, les falla a algunos que estan fuera de dominio y a otros que si estan en el dominio ya reinicie el servicio Microsoft Excahnge System Attendant. pero la falla continua
La solucion que encontre fue configurar RPC sobre Http en el outlook, pero los equipos que estan fuera de dominio marca error de certificado.. asi que el problema continua
este hilo ya tiene años.. alguien tendra ya alguna respuesta ?
de antemano gracias
Just wanted to say that the numerous other registry fixes that are floating around out there (autodiscover, defconnectopts, etc) didn't work for me - this did. Had a customer upgraded from Office 2003 to 2007 - suddenly no connection to exchange, and couldn't create a new profile (because it won't talk to exchange). I exported the key from my computer to hers, made a few adjustments, and BINGO - customer has functional outlook.
It appears that the issue may be the RPC encryption setting. I have existing user accounts that connect to Exchange 2010 with no problem. However, several new accounts on the same PC are getting the "unable to connect to server..." message (I am testing these accounts before I do a forest migration from exch2003 to exch2010). Come to find out the upgrade to SP1 cause a change in the RPC setting. When I disabled the requirement for RPC encryption on the CAS server, my new accounts were able to connect to the 2010 exchange server with no problem. Even though the new accounts had the RPC encryption setting check, it still did not sync with the exchange server RPC encryption setting. It appears you have to:
- turn the RPC encryption off on the server,
- start the Outlook client to get it connected to the server,
- then configure the encryption on the client log it off
- then configure the RPC encryption on the server
- then reconnect the Outlook client and it should work from then on
See the following for further info.

I know this post is over 3 years old, but I encountered the same issue and none of the above resolved it.
After running a port scan on the computer that was not connecting, I learned that nearly all the ports to this computer have been turned off, especially ports 25 (SMTP), 53 (DNS), 88 (Kerberos), 137 (NetBIOS). After enabling these ports, I was able to connect to Exchange and create an Outlook profile.
The FIX IT here http://support.microsoft.com/?kbid=319206 works, but only for a user who's already logged in (if you just run the fix it program and do nothing else). To make it work for all users you'll need to manually edit the registry as it says in the article.
To force Outlook to use a pre-defined global catalog server, use the following steps to set the following special registry parameter to point to the Fully Qualified Domain Name (FQDN). Doing this over-rides any setting in the MAPI profile.
- Click Start, and then click Run.
- In the Open box, type regedit.exe, and then click OK.
- Locate and then click the following key in the registry:
Note You may have to create the registry path.
- On the Edit menu, click Add Value, and then add the following registry value:
Value name: DS Server
Data type: REG_SZ (string)
Value data: FQDN of the global catalog server
This allowed me to roll out a bunch of laptops and not have to worry about running the Fix It for each user.
update: Sysprep seemed to remove fix. Each time a new user logged into a newly imaged laptop (on domain) same error about Outlook 2007 cannot connect to Exchange. Have tried just about everything, but all I seem to be able to do is run this stupid Fix it each time. Luckily I don't have 1000 machines to setup because then I'd be screwed.

How do you check to see if it's turned on? I need like detls on how to find it. n what files they are in thank you. I've never had outlook operating on my comp n I'm trying to set it up but am having alot of trouble so please if some one can help me I will be greatly appreciative :) Thank you
I have had this problem and tried all the tricks on the internet and the only thing that worked perfectly was the "fix it".
It changes your Exchange Provider in the registry to the closest global catalog server. Try it, it works.

My fix was a combination of: http://support.microsoft.com/?kbid=319206 and deleting the Outlook folder located in the USER\appdata\local\Microsoft\, it deleted an OST that was in there that SEEMS to have been a part of the problem.
I have to keep an eye on this issue though. Not the first time I've had this series of errors on a machine here on my network and I'm wondering if I've got a boinked Exchange server that has an issue or two not smoothed out.
The same problem happens to me. However I have sucess in access via Outlook Web App and iPhone and the internal network, but always gives the same error when I try to set up an external exchange account in Outlook by creating a new profile. Does anyone can help me solve this issue?
