You can run the “Test Email AutoConfiguration…” to see if the OAB is now being passed to your clients.
There will also be a delay where you’ll need to wait for your Outlook clients to refresh their autodiscover configuration. Set-OfflineAddressBook -Identity “Default Offline Address Book (Ex2016)” -GlobalWebDistributionEnabled $trueĪnd finally let’s confirm to make sure the changes take effect and look for the values of “GlobalWebDistributionEnabled” and “WebDistributionEnabled” using the command:Īfter making the above changes I recommend issuing an “iisreset” or restarting your Exchange Server.
Now let’s set the “GlobalWebDistributionEnabled” flag to True using this next command: Let’s find the name of your Offline Address Book by running the command below: When setting this second flag to True, it also sets the first one above to True as well. There’s also a different flag “GlobalWebDistributionEnabled”, which is recommended to be enabled as well on Exchange 2016. 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). I finally discovered that the “WebDistributionEnabled” configuration flag was marked to False, when it needs to be marked as True. I couldn’t find any references of this occurring to other users. It simply wasn’t being passed to Outlook clients. All my virtual directories and URLs were fine, and the OAB was being generated fine without any issues. I spent 3 hours trying to find out why this was happening (I assumed it was configuration and/or IIS authentication related). Also when using the “Test EMail AutoConfiguration.” (by holding CTRL and right click on Outlook System Tray icon) to examine the AutoDiscover information, there was no OAB URL (OABUrl in XML) being sent to the clients.
When trying to perform a manual download (Send and Receive -> Download Address Book), it wasn’t in the list. When you’re finished you can turn down the diagnostic logging again.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. In any case turning up the diagnostic logging should result in event log entries that tell you why the issue is occurring. That was the solution in my case, though it is possible you will encounter other root causes of the issue. All I needed to do was re-enter that attribute and the user appeared in the OAB when it was next updated. In this particular case the SMTP address attribute of the user object was corrupt. OABGen will skip user entry ‘Ann Parker’ in address list ‘Global Address List’ because the SMTP address ” is invalid. Event ID 9325 contains the reason for a given object being skipped by the OAL generator. On the next offline address book generation attempt more details were logged to the event log. C : \ > Set - EventLogLevel "SERVER1MSExchangeSAOAL Generator" - Level High
To see which entries are affected, set event logging for the offline address list generator to at least medium.įollowing the advice in those events I turned up the diagnostic logging level for offline address list generation on that server.
OABGen could not generate full details for some entries in the offline address list for address list ‘Global Address List’. To see which entries are affected, event logging for the OAL Generator must be set to at least medium.
OALGen skipped some entries in the offline address list ‘Global Address List’. Looking into it I found some warnings on the mailbox server that was responsible for generating the offline address book.
After the usual OAB update period had passed they were no longer appearing under the old or new name, though they appeared in the GAL itself when searched via OWA or an online Outlook client. This person had recently changed their name and the user account and Exchange details were updated with the new name. I worked on a case recently where one particular user was not appearing in the offline address book in an Exchange 2010 organization.
