Hi, I am having a strange problem on the address book between Outlook 2007 and Microsoft Exchange Server 2007. I can open address book and download the offline address book with no problem. The problem is when I left the outlook 2007 idle for a few minutes, then I click on Address Book, then it will pop up the error message "The connection to Microsoft Exchange server is unavailable. Outlook must be online or connected to complete this action." But after I close the message box, the connection to the server resume and I can open the address book with no problem. I do know that this isn't a big issue, but this is really annoying. I have tested setup outlook on a few pc, all the pc also facing the same problem except the Exchange Server itself will not have this issue. I have tried to google for solution, but couldn't find any solution for it yet.Is there any expert that could enlighten me on solving this problem? Thanks in advance.

Well, I have never heard of that, but what Windows version are the clients running? Any client-based firewalls enabled? Server firewall enabled? Or a firewall in between the server and clients?

Cached mode or online mode clients?Active Directory, 4th Edition - www.briandesmond.com/ad4/

Are you running the Exchange server in a cluster or is it standalone. can you access the address book share via a unc path which should be something like:\\exchangeServerName\ExchangeOABThanksRobin

Hi,I have seen this error when exchange BOX have resource issue. Please check health of exchange server randomely. But stili not looking much from sevrer side issue but i will recommend you to enable diagnostic loggoing to generate more event and see.Anil

you could also try switching on extra logging in outlook 2007 follow this article to find out how to do it:http://office.microsoft.com/en-us/outlook/HA012304211033.aspxRobin

there is no issue in your client system or in exchange server..It is network isuue.Check the response from the server by ping command.

Hi all, Sorry for the late reply. Andy_D: "Well, I have never heard of that, but what Windows version are the clients running? Any client-based firewalls enabled? Server firewall enabled? Or a firewall in between the server and clients?" Hi Andy, thanks for the post. The clients are running on Windows XP with SP2 and some are on SP3. As for the firewall, i had already disable all the firewall, the connection between the server and clients are fully enabled. Brian Desmond "Cached mode or online mode clients?" I had tried both, both had the same issue. Robin Ferris Are you running the Exchange server in a cluster or is it standalone. can you access the address book share via a unc path which should be something like:\\exchangeServerName\ExchangeOAB Hi Robin, I had tried your suggestion, it is able to open the UNC path. The server is setup standalone (Hub Transport, Mailbox, Client Access, Unified Messaging) together with the active directory, and subscribed to another server with the edge transport roles.

Thanks for the help. m_pradeep there is no issue in your client system or in exchange server..It is network isuue.Check the response from the server by ping command. Hi pradeep, I had tried the ping to the server. It results only 4ms without packet lost for long time. And I have others computer that ping over internet for about 300ms without any packet lost too. Both side of the PC also having this problem if the Outlook 2007 keep idle for about 5 minutes. Thanks for your help. Hoping for more suggestion to solve this problem.

Hi Robin and Anil, Here is the outlook 2007 logging data from a client pc with Windows XP Professional with SP2. And the pc is joined to the same domain as the Exchange Server domain.

that doesn't immedicately give me an answer, so will have to look a little more into that log.have you tried doing a packet capture using network monitor blog here http://blogs.technet.com/netmon/and capturing from just before the error until just after. the smaller the better.you should be able to see the request going out for the address book in the capture and see where it's going etc Robin

ow another thing I forgot was to say touse the outlook connection status checker and also autoconfiguration tester, you can get to these by right mouse clicking on the outlook icon in your task tray and holding ctrl at the same time.Then choose whic one to run, the status checker would show you how many requests/failures you are getting and the autoconfig would see if everythign is pointing to the riught place as well.Robin

Hi Mike, Yes, 10.40.0.80 is Gc server with exchange server and 10.10.10.155 is the outlook client I will check first the error code 0x1C00001A problem and see the detailed information about that.

Hi Mike, i already do the way as u recommend to me , but the outlook problem still appears . Is is till have other ways to solve my problem. Thanks for help me everyone.
