Hi All, I have read every post I can find for this problem and tried everything suggested in the posts. I have a few Outlook 2007 clients that get stuck on downloading the OAB. I've checked the auto discovery with www.testexchangeconnectivity.com and passed. Also by CTRL+Right-Clicking the outlook icon and doing the auto discovery test there with these results: Autoconfiguration has started, this may take up to a minute Autoconfiguration found the following settings: Display Name: Rob W Internal OWA URL: https://exchangeserver.my.domain.edu.au/owa External OWA URL: https://webmail.domain.edu.au/owa Protocol: Exchange RPC Server: exchangeserver.my.domain.edu.au Login Name: robw Availability Service URL: https://webmail.domain.edu.au/EWS/Exchange.asmx OOF URL: https://webmail.domain.edu.au/EWS/Exchange.asmx OAB URL: https://webmail.domain.edu.au/OAB/<guid>/ Unified Message Service URL: https://webmail.domain.edu.au/UnifiedMessaging/Service.asmx Auth Package: Unspecified Protocol: Exchange HTTP Server: webmail.domain.edu.au Login Name: robw SSL: Yes Mutual Authentication: Yes Availability Service URL: https://webmail.domain.edu.au/ews/exchange.asmx OOF URL: https://webmail.domain.edu.au/ews/exchange.asmx OAB URL: https://webmail.domain.edu.au/OAB/<same guid as above>/ Auth Package: Basic Certificate Principal Name: msstd:webmail.domain.edu.au I'm leaning towards an IIS7 permissions issue. The permissions set on C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB are: Authenticated Users Read Enterprise Admins Read Domain Admins Read Exchange Organization Administrators Read Exchange Servers Full Control Administrators Full Control I've also tried deleting the Default Offline Address Book and creating a new one. Deleting the OAB virtual directory and re-creating it. Deleting the directory from C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB and C:\Program Files\Microsoft\Exchange Server\ExchangeOAB, restarting the Microsoft Exchange System Attendant service and Microsoft Exchange File Distribution service which created the folders again so that's working. I can access the https://webmail.domain.edu.au/OAB and https://webmail.domain.edu.au/OAB// urls through IE and se ethe list of lzx files and the oab.xml file. I don't have a web.config file in C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB but not sure if that would do anything and don't know how to get one there. Please any and all help is appreciated

You didn't share your Exchange version, service pack and rollup hotfix level. Have you configured Web Distribution? Check out these articles. They're for Exchange 2007 but pretty much apply to 2010 as well. http://msexchangeteam.com/archive/2006/10/16/429204.aspx http://msexchangeteam.com/archive/2006/11/15/431502.aspx Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi Ed, I knew I was leaving something out hehe. Exchange 2007 08.02.0176.002 which I believe to be SP2 I'm aware there is SP3 and am currently trying to organise/convince the board to update. Thank you for those links, I'd already found them and been through them.

Have you run ExBPA? It may uncovoer incorrect rights on the OAB directory.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hello Rob, Is it all users or just some? Does it generate an error? We find that a lot of our users on our infrastructure get problems when doing Offline address book and Out of Office. The error code is normally; 0X8004010F The fix we usually give the customer is by adding a DNS SRV record that looks a little something like; _autodiscover._tcp.domainname.com SRV 0 5 443 exchange.servername This then allows it to get the autodiscover.xml file from the server, and get the required data that is needed to build the OAB and connect to Out of Office. Regards CJ.

Hi Ed, I've just run the ExBPA permissions and connectivity reports. I've added the connectivity report below - the permissions one was much larger. I'm not really sure what I am looking for in these reports, but everything looks good to me :S I also installed UR5 while I was there which hasn't helped any :( Detailed View Exchange Organization configurationNamingContext =CN=Configuration,DC=my,DC=domain,DC=aust,DC=edu,DC=au Microsoft Exchange distinguishedName =CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=my,DC=domain,DC=aust,DC=edu,DC=au Educational Institute distinguishedName =CN=Educational Institute,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=my,DC=domain,DC=aust,DC=edu,DC=au cn =Educational Institute Admin Groups Exchange Administrative Group (FYDIBOHF23SPDLT) distinguishedName =CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=Educational Institute,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=my,DC=domain,DC=aust,DC=edu,DC=au cn =Exchange Administrative Group (FYDIBOHF23SPDLT) Found administrative group Exchange Administrative Group (FYDIBOHF23SPDLT) in the directory.

Hi C.J, As far as I know it is only happening to a few users. Not everyone has complained about it (yet). There isn't an error as such, actually, at this point I'd almost settle for it to error out. It hangs on 'Offline address book Connecting to Microsoft Exchange' when you bring up the 'Outlook Send/Receive Progress' dialog. It wont move any further until you hit cancel task. Can you elaborate on your fix a little, I'm not sure I understand it :S

Hello Rob, By all means. The issue you are discussing is similar to what we have, where they can't access the Offline Address Book and also the Out of Office feature. I guess this broken also for some of your uers? When looking at the machines normally we find that it is trying to get the xml file from either a wildcard A Record in the domain, or autodiscover.domain. This then results with the Autodiscover data not being found. This is usually because your machine is unable to gain a connection when connecting externally of a domain to the autodiscover.xml file that contains the information you require for these Outlook 2007 / 2010 features. I know how frustrating this is but there is a solution so long as your Autodiscover is configured correctly. If you go to your DNS admin panel for your domain you new to add an SRV (Service Record) this record will look a little like this; _autodiscover._tcp.domainname SRV 0 5 443 exchange.domainname You may need it like this: Hostname: _autodiscover Protocol: _tcp Type: SRV Priority: 0 Weight: 5 Port: 443 Value: exchange.domain (or whatever your external address is) once this then updates it should then appear with an alert within Outlook which says do you trust; exchange.domain/autodiscover/autodiscover.xml you will need to accept this. Another issue I see is wildcard records in a domain. Outlook take this and looks for autodiscover.domainname and tries to install the certificate off the web server. As guessed this won't work. The best option to get around this is to remove the * wildcard and setup an SRV instead. The other way to override this, is to get a copy of the autodiscover.xml file, and add it to your computers registry. This usually goes in; HKEY_CURRENT_USER > Software > Microsoft > Office >(number of office version) > Outlook > AutoDiscover V14 = Office 2010 V12 = Office 2007 Then if you add a string called; domain.com (this will be your domain). The value is your location of the autodiscover.xml This will then mean you don't have to have an SRV record as some DNS hosts don't allow it. Hopefully this explains it a little better for you. Regards CJ.

May want to take a look at this and see if it helps. I had this problem and it was haning on OAB. Error message when Outlook clients synchronize an OAB with Exchange 2007: "0x80190193" http://support.microsoft.com/kb/951576

Hi C.J, I tried both of these an neither worked. I was curious and opened the Autodiscover file and all it has in it is: <?xml version="1.0" encoding="utf-8"?> <Autodiscover> <!-- This is a placeholder file --> </Autodiscover> Should there be something more in it?? Hi btenney, Thanks for your suggestion. I read the article and disabled the require ssl check box but every time I did an iis reset it put it back on :(

Hello, Try resetting the autodiscorver VD by refering to the following link: http://technet.microsoft.com/en-us/library/ff629372.aspx#Shell Thanks, Simon

Hi Simon, Thank you for your suggestion. I tried to follow the instructions from that link for the EMC and shell but neither worked. I looked into the permissions I require to have those option available, and my user has them, but still the options to rest weren't there :(
