Forcing updates on OAB - EX2016

David Zemdegs 1,596

Hi,
I did the following on our Exchange 2016 to force a change to some recipients to flow to Outlook.
get-globaladdresslist | update-globaladdresslist
get-offlineaddressbook | update-offlineaddressbook
Then used Outlook to download the offline address book.

Outlook still has not been updated. Did I miss something?
Thanks
David Z

Answer 1

Hi @David Zemdegs ,

Is the new change available in Global address list? You can login to OWA and check if the new change has been updated.

Was it working before?
Is this happening to all users or only few users or one?
Did you get any errors while running those commands?

Run the below commands to check the OAB,

Get-MailboxDatabase | Format-Table -Auto Name,OfflineAddressBook
Get-Mailbox -Arbitration | where {$_.PersistedCapabilities -like "OAB"} | Format-List Name,ServerName,PersistedCapabilities
Get-OfflineAddressBook | Format-List Name,AddressLists,GeneratingMailbox,IsDefault

Thanks.
From my original post - the change did not appear in outlook after those three steps.
Am I missing a step?

Steps are fine but to narrow down, please provide the details,

Is the new change available in Global address list? You can login to OWA and check if the new change has been updated.
Was it working before?
Is this happening to all users or only few users or one?
Did you get any errors while running those commands?

Because if the issue is with one user, it could be problem with client side (outlook) or if its few or more users then it has to be checked from the server end like OAB configuration, generation, URL's etc.

Thanks. I just needed to know whether all the steps are OK to force an update to a recipient, particularly display name, to appear in outlook.

Hi @David Zemdegs ,

Have you assigned the Address Book Policy that include this OAB to the mailbox?
As you just want to update the OAB, what you did is totally enough. You can check it by:

Get-Mailbox "Mailbox"| FL OfflineAddressBook

If you didn't assign the ABP to this mailbox, the Outlook & OWA may not update. For more things about ABP: Address book policies in Exchange Server
