Hi Prince, Have you set internal and external OAB URL on hub/cas server? PLease refer http://technet.microsoft.com/en-us/library/bb124270(EXCHG.80).aspx Happy Mailing :-)

Hi, Please check whether the below link can help you: http://bradmarsh.net/index.php/2009/03/03/exchange-2007-offline-address-book-oab-keeps-asking-for-authentication/ Thanks Allen

Hi Prince, Try to set the loggin level higher on the mailbox server. get-eventloglevel | set-evenloglevel -level high You should see a more detailed error logging in the eventviewer. to turn it back to normal: get-eventloglevel | set-evenloglevel -level lowest Greetzz, Timmy

this is the commadn that i have to use tet-EventLogLevel "MSExchangeSA\OAL Generator" -Level high

You can use that command to set the level of logging. get-eventloglevel "MSExchangeSA\OAL Generator" | set-eventloglevel -level High than you can check out the eventviewer for more detailed troubleshooting. Pls post some of them for further investigation... Greetzz, Timmy

when I type this command set-eventloglevel -level high It ask me about the identity Here i have to type OAB address book name or ?

Identity is the name of the diagnostic object you want to set. "MSExchangeSA\OAL Generator" Or use the EMC GUI if at Exchange 2007 Sp2

when i try to run this command i got this error. [PS] C:\Windows\System32>set-eventloglevel -level high cmdlet set-eventloglevel at command pipeline position 1 Supply values for the following parameters: Identity: "MSExchangeSA\OAL Generator" Set-EventLogLevel : Cannot bind parameter 'Identity'. Cannot convert value ""MSExchangeSA\OAL Generator"" to type "Micr osoft.Exchange.Configuration.Tasks.ECIdParameter". Error: "'OAL Generator"' is not a valid value for the identity. Parameter name: Identity.EventSource" At line:1 char:18 + set-eventloglevel <<<< -level high

I go through these documents but i am not be able to get the solution

Hi, If you are Running Exchange 2007 CCR/SCR then below steps will help you : 1. Start Registry Editor on each CCR/SCR node, and then verify that the following registry subkey is present: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ MSExchangeSA\Parameters\<ServerName> \EnableOabGenOnThisNode If the registry entry does not exist, create the following registry entry: Value name: EnableOabGenOnThisNode Value type: REG_SZ Value data: primary CCR/SCR node name 2. Verify that the EnableOabGenOnThisNode value is set to the host name of a valid CCR/SCR node. By default, the registry entry is set to the host name of the primary CCR/SCR node. 3. If the CCR/SCR node that is specified in the registry entry is offline, bring the CCR/SCR node back online, and then configure the CCR/SCR node as the primary node again. 4. If the CCR/SCR node cannot be brought back online, change the EnableOabGenOnthisNode value to that of the secondary CCR/SCR node. For example, change the registry value to Node2. 5. By default, OAB generation for public folder distribution runs at 5:00 A.M. each day. To immediately update the OAB for public folder clients, follow these steps: a. On the Mailbox server, start the Exchange Management Console. b. Expand Organization Configuration, and then click Mailbox. c. Click the Offline Address Book tab, right-click the offline address book and then click Update. (By default, the address book is named Default Offline Address Book.) d. Click Yes to confirm that you want to update the OAB. By default, OAB generation for Web-based distribution runs every eight hours. To immediately update the OAB for Web-based distribution, follow these steps: e. Start the Services Microsoft Management Console (MMC) snap-in on the server that runs the Exchange 2007 Client Access server role. To do this, click Start, click Run, type services.msc, and then click OK. f. In the Services list, right-click Microsoft Exchange File Distribution, and then click Restart. 6. Verify that the OAB was generated successfully. To do this, start a Microsoft Office Outlook 2007 client that is configured to run in Cached Exchange Mode. Then, download the OAB Dinesh

Please also check the path to OabDropFolderLocation that may be incorrect - HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeSA\Parameters\your_server\OabDropFolderLocation Does it point to a valid (correct) drive? If not, change it to the correct one. <!-- /* Font Definitions */ @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:204; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-520092929 1073786111 9 0 415 0;} @font-face {font-family:"Trebuchet MS"; panose-1:2 11 6 3 2 2 2 2 2 4; mso-font-charset:204; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:647 0 0 0 159 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt;} @page WordSection1 {size:8.5in 11.0in; margin:56.7pt 42.5pt 56.7pt 85.05pt; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.WordSection1 {page:WordSection1;} --> It must point to a valid location like <disk:>\exchsrvr where <disk:> reflects real physical location of this folder. If this is the case, regenerate OAB after that. MCITP: Enterprise Messaging Administrator
