Adress List not showing in Outlook Client or OWA

New Contributor



we have exchange hybrid environment and I want to create a custom address list for our pool cars/projectors/cameras.

Since this can be done only over Powershell I execute a simple command: New-AddressList -Name 'Pool Cars', recipientfilter needs fine tuning but I have manged to get one car into the list with the customattribute1 which has a value: car. So far so good. But the list is not showing in the outlook client or outlook OWA.

We are currently having a problem when downloading an OAB, and it states 0x80190194, event viewer shows "OAB Download Failed. (Result code in event data)." Event ID 27".  I expect this to be solved by our colleagues but I should still be able to see the new list in OWA?

Am I missing some step to enable the list in the outlook address book? It is being listed under root container or \.

Yes, address lists should be visible in both premises, provided you created the address lists in both locations (on-prem & online).

Hi @Tonito_Dux,

I was able to reproduce your issue. I created an AddressList named 'Pool Cars'. This one wasn't available in OWA/Outlook.

After that, I created a new one wit the following cmdlt:

New-AddressList 'Pool Cars' -Container "\Pool Cars"

Same result. Address List missing. Then I edited it like the following, ( only as example/testing :(

Set-AddressList 'Pool Cars' -RecipientFilter "(RecipientType -eq 'UserMailbox')"

After some minutes of replication, the address list was available:


You could also check the address list state with:

Get-AddressList 'Pool Cars' | fl Container,Path,DisplayName,IsValid,IncludedRecipients


Regarding missing object in a Hybrid environment address list, that's a know issue and easy to fix:

Regarding the OAB error, please check:

Hope this helps.



thank you for your thorough answer and sorry for not replying before. I was able to solve the problem in the meantime the same way you did.

• Connect to EXO PS.
• New-AddressList –identity “Name”
• New-AddressList –identity “Name” –Container “Main Folder Name” – this will create “Name under “Main Folder Name”, like a tree structure.
• Recipient filter has to be then definied for the new address list otherwise it wont hold any users/objects/resources.
Example of a filter for a car resource:
set-addresslist -identity 'Autos' -recipientFilter "(CustomAttribute1 -eq 'Auto') -and (RecipientType -eq 'UserMailbox')"
Custom Attribute has to be defined on the object in local EX or AD under “externsionAttribute1”.
• Force AD Sync
• Wait for 5-10min
• Check if the wanted members are in the new addresslist:
get-user -filter "((CustomAttribute1 -eq 'Auto') -and (RecipientType -eq 'UserMailbox'))"
• IMPORTANT: If nothing is listed, then update the object in AD with ANY value just to initiate the “refresh”. For example add a city to the object and the force dir sync. Later remove the value.
• Run “ Get-AddressBook | Update-AddressBook “ in EXO

There are couple of screenshots missing with the steps outlined above but it is because there are some company related info which I want to keep out of public.
