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

    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?
