Do you have a pf primary hierarchy?

And did you update exchange in the past (2010 or lower) where oab / address lists might be not migrated correctly?

Yes I have PF primary hierarchy It's Organizational unit: on the Top Domain

No it New Exchange 2016 {Version 15.1 (Build 1466.3)}

Can you run the shell commands manually to see if they work (for existing resources) ?

Sometimes it can be a result of a faulty installation if the commands in shell do not work (if thats the case a CU upgrade would often help).

For example This command

""Cmdlet failed. Cmdlet Get-AddressList, parameters -Identity “TestHostedDomain.com Address List” -DomainController “DC.Domain.LOCAL”.""

Successfully run If run I run it like this

Get-AddressList -Identity “TestHostedDomain.com Address List” -DomainController “DC.Domain.LOCAL”.

Furthermore,

I will perform Exchange CU12 Update and test again after update
