Outlook clients not updating oab optimize the boot image updating process
Knowing why the delay occurs means you won’t spend time troubleshooting it.
After doing a migration from Microsoft Exchange 2013 to Exchange 2016 I noticed that my Offline Address Book (OAB) wasn’t being made available to Outlook clients.
When i look in this folder (C:\Program Files\Microsoft\Exchange Server\V14\Client Access\OAB) on the IIS server, I see a folder with date modified today, but the files in this folder have all modified date a few months ago ? Ive also found a folder (C:\Program Files\Microsoft\Exchange Server\V14\Exchange OAB) which contains more recent files but not from today when i updated the offline address book via the exchange management console What am i missing ?
Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.It needs to be run on Exchange shell on Exchange server :) Look ideally the OAB update happens everyday at midnight so either you wait for sometime or once update happens need to check if its few days then if OAB is getting generated on the Mailbox server "Exchange OAB" folder and Transferred to CAS server and "OAB" folder is updated with same GUID folder and LZX files till today.- Rancy Yes thats the update on Mailbox if for some reason FDS service on CAS cannot pull thats where the clients (Outlook) will pull the OAB data from.I finally discovered that the “Web Distribution Enabled” configuration flag was marked to False, when it needs to be marked as True.This flag when set to true, allows it to be distributed (Note/Fun Fact: There’s a separate and different flag for older Exchange versions where the OAB is inside of the Public Folder Store).
