Outlook 2007 on Vista x64 won't connect to Exchange 2007

I recently upgraded one of our machines to Windows Vista Ultimate 64-Bit and Office 2007 Professional. Prior to this upgrade the OS was Vista Business 32-Bit and Office 2003 Pro. With the old set up Outlook connected seamlessly to our Microsoft Exchange Server 2007 (Running 2008 Server). Since the upgrade, all I get when trying to setup a profile is the following error. I can connect to the mail server directly, Remote Desktop, or via a Ping.

"Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."

I've read previous posts both here and abroad telling me to check my firewall, do outlook updates, etc, and I've been unable to clear this error. I've created multiple profiles and have had no luck. I even put in the old hard drive and launched it successfully running 32-Bit Business & Outlook 2003 as was previously installed.

Most recently I attempted statically assigning my network information because of a possible Network Gateway issue. http://support.microsoft.com/kb/913843 . This didn't change the error message either.

Thank you for help.

Am I missing something?

When creating new profiles do you mean outlook or computer? Also try uninstalling office 2007 completely deleting the folder and reinstalling with out any updates sometimes its simply the microsoft updates dont install right

also i copied this from the link

The post below was listed on this link http://office-outlook.com/outlook-forum/index.php/m/102050/ if you are using vista please check to see if this is an issue that could help your situation.

Hi all,

I've found the answer to my problem. It is the new tcp autotuning option in
Vista. I just disabled the autotuning and my problems have gone away. I ran
the following command:

netsh int tcp set global autotuninglevel=disable

There is definitely lots of discussion in various forums out there about the
benefits (or lack of) with respect to this autotuning. Have a look at the
following:

http://www.msfn.org/board/lofiversion/index.php/t87969.html

I'm definitely disappointed that this wasn't discovered ages ago by
Microsoft. This is a default install of the OS and Outlook and it doesn't
work? Wow...

Anyway, hopefully this post is useful!

Thank you for help, but I've reloaded office itself twice now.

I did try that command, and it still provides me with the same error upon launching outlook.

Turn off the firewall, and turn off UAC (User Access Control).

When reloading office did you scratch out all the old office files?
Microsoft office uninstall is stupid (For lack of a better term) it leaves all sorts of crap behind. I would do another uninstall, delete the below applicable files/folder (Anythingwith office or outlook) and then the registry keys.

C:\Documents and Settings\All Users\Application Data\Microsoft\OFFICE
C:\Documents and Settings\username\Application Data\Microsoft both outlook and office folders
C:\Documents and Settings\username\Local Settings\Application Data\Microsoft

delete all the office keys especially the outlook you can use these for

Ok,

I've turned off UAC, The firewall (entirely), no anti-virus is installed (has never been, fresh install), and I just re-loaded office, removing all above applicable files, including the registry keys. The license keys have also been wiped prior to install.

It still tells me the Exchange Server is offline, when OWA works fine, and I'm actually logged in with my own user on Vista Business x32 and office 2003 currently.

try not using the auto configuration and do a manual configuration

Here's a thought from out in Left Field - remove and re-add that local host to your domain.
I used to get some of the screwiest error messages and the bottom line was often some kind of 'authentication' error messages in the Event Viewer logs.

You have check your logs, right?

ASKER

Yes, I've checked the logs and nothing seems to be going wrong. I just readded the host of the machine to my domain, to no avail.

ASKER

I've went as far as to use an entirely different user account on the domain, setting up an entirely different email address, and I get all the same errors on this system. I currently do not have any other x64 vista ultimate machines on the network running office 2007. I do have one running 2003 just fine, though..

kyleldi - My comment was just a SWAG, but thanks for checking.

See if this work around helps

Augwest,

That workaround refers to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC in the Registry, and I don't see an RPC in my reg.

Right click on outlook do Add a new key and name it RPC

and do the rest from there

ASKER

Thanks, I tried doing the workaround as described in the MS support page and still had no success. The same error continues. I re-created the profile as well.

kyleldi -
I just did the RFA for you and a Moderator will increase the Zones and send out the Expert Alert.

a new computer usually do not comes with the certificate of the exchange server (assume it is not standard)

for RPC to work, you need to have the exact SSL certificate

please make sure you got the right information.

Am I correct in assuming that you are connected to a domain with exchange on it?
If so have you connected the computer to the domain?
Have you tried resetting the computer account?
Can you access shared folders?
Have you tried doing a manual configuration of outlook?
If you hit test settings while showing up what errors out?
Is your mailbox itself over the size limit?

ASKER

I believe everything is working correctly from that side of things. I have the certificate installed, and I can access it via OWA without any problems, so I don't believe it's the certificate. Any other ideas?

I meant if you hit test settings, while configuring the account manually what errors out.

ASKER

It fails at Log On To Server.

Prior to that it pops up asking about the ssl cert, which it always does in 2007 on other systems. If I install the cert it's not not a problem.

Have you updated 07 Office to Service Pack 1, there is a hotfix included in that update that correlates to this issue.

See Here:

http://support.microsoft.com/kb/968858

ASKER

Yes, I installed SP1 & 2 as well.

Try logging into the computer with a different network account it looks like it maybe something in the profile.

That looks like your doing an automatic setup.
Try putting the settings in manually, you should have little box you can check when first setting up the exchange server.

ASKER

Yeah I've done that as well, same error.

and have you tried using a different network account?

Of possibly tried Resting the users password and then having them log in, it maybe more an issue of AD authentication than Exchange authentication

ASKER

Yeah, I've used four different accounts in all, changing passwords on all. For some reason or another it only seems to be office 2007 on vista x64. I've got it running fine on several xp machines.

when you go through the manual setup do you use the fully qualified domain name for the exchange server?

ASKER

Yes, I do.

Quick question is the fire wall on the 64bit machine on or off?

ASKER

I've disabled it, just to eliminate from the equation, and no antivirus has been installed, yet. Windows defender has also been disabled.

And are you using Cached mode or regular?

ASKER

I typically don't set up machines to Cache because of our large volume of email trafficking, but I've tried it both ways.

I can't remember if you can or not, but have you tried just an Ip address for the server?
Also can you access shared folders on the server?
What happens if you try and telnet to it?
(Note vista is dumb in my tech opinion so you probably have to turn it on)
Go to control panel->programs features->Turn windows features on or off->select telnet client
to telnet to it just go to a command prompt and do a telnet serverip 25
example if your e-mail server ip is 192.168.1.100 then;
telnet 192.168.1.100 25
It should give you a mail header
