Why is the GAL not updating on Exchange Server 2016?

I have been adding users and mailboxes but the global address list is not updating. The users show up on All Users but not the GAL. When I try to download the default global address list I get an error (0x8004010F): The operation failed. An object cannot be found. I have inherited this Exchange server from a prior tech and am not sure what is wrong.

Hi @TommyZittrauer-1932,

The users show up on All Users but not the GAL.

Did you check it via Outlok which is running in Exhcange cached mode?

If this is the case, please follow the steps below and see it the error persists:

1.Open EMS, run the following commands:

 Get-GlobalAddressList | Update-GlobalAddressList
 Get-OfflineAddressBook | Update-OfflineAddressBook

2.Try again in Outlook and check if the updated OAB can be downloaded properly:

3.If the above doesn't work, it's suggested to try createing a new OAB, assign it to one of the affected user mailboxes, wait for a few hours or creating a new Outlook profile for the user to check the result:

 New-OfflineAddressBook -Name "Test" -AddressLists "\Default Global Address List"
 Set-Mailbox -Identity user1 -OfflineAddressBook "TEST"

If the new OAB works for the user, chances are that the issue is due to the corrupted default OAB used earlier, then you can assign the new OAB to the mailbox databases and then reset IIS for the change to take effect:

 Get-Mailboxdatabase | Set-MailboxDatabase -OfflineAddressBook "Test”
 Get-MailboxDatabase | Ft Name, *book*
 Set-OfflineAddressBook -Identity "Test" -VirtualDirectories $null -GlobalWebDistributionEnabled $true

Name Versions AddressLists


Default Offline Address List (Ex2013) {Version4} {\Default Global Address List}
Peek {Version4} {\Default Global Address List}

I also tried to add a new offline address book and this was my message: WARNING: The command completed successfully but no settings of 'domain.local/Users/user1' have been modified.

Hi @TommyZittrauer-1932,

Outlook is using Cached Exchange Mode currently.

Are you able to see the new added user in OWA or in GAL when Outlook is switched to Online mode? If yes, then we can conclude that the issue is with the Offline Address Book.

I also tried to add a new offline address book and this was my message...

If it has been narrowed down to be with the OAB, would you mind running the command below to verify if the new OAB has been applied to the user?

 get-mailbox user1 | fl offlineaddressbook
