"..Unnatural work produces too much stress.."

Exchange2010 – OAB/Outlook clients not downloading updated OAB

Issues:

  • Outlook on Cache mode not updating..Disabling Cached mode on client manually fixes the problem.
  • OWA is not affected at all. All changes are instantly reflected in OWA.
  • Deleteing the .oab files in the user app data folder fixes the problem

This is not  a solution to this issue.

Create new OAB and perform the following tasks:

  1. Create new OAB from EMC.
  2. Make sure Web based and Public Folder distribution is enabled.
  3. Restart MS Exchange System Attendant and File Distribution Service.
  4. Update the OAB from EMC and Set it As Default.
  5. Associate the new OAB to Mailbox Database.
  6. Check the location for the .LZX files C:\Program Files\Microsoft\Exchange Server\V14\ExchangeOAB
    and C:\program files\Microsoft\Exchange Server\V14\ClientAccess\OAB\
  7. Make sure you don’t have web.config file @ .LZX file location.
  8. I hope you are doing full download of the OAB in Outlook.
  9. When you download the OAB, Make sure you uncheck the box“Download changes since last send/recieve”
  10. “Global Address Book” is the only option
After you restart the File Distribution Service on the CAS server, you should be getting the same files from the OAB generating server to the C:\program files\Microsoft\Exchange Server\V14\ClientAccess\OAB\ on the CAS server . You might want to set the logging level to high to see if any errors are generated on the OAB generating server.
 
  • Set-EventLogLevel –Identity LABMBX\MSExchangeSA\* -Level High 
  • Set-EventLogLevel –Identity “LABCASHT\MSExchangeFDS\*” -Level High
 the first one will get the OAB events and the 2nd will get the File Distribution Service events. Dont forget to set the logging back to defaults. After setting the logging, regenerate the OAB and then restart the FDS, check for errors in the corresponding event logs.
 
Wait for 24hours to get the replication
