Hi @exchange beginner ,

You can create new OAB and make it as default. Please follow the steps,

Hi,

Is it possible?
Yes. You can create a new OAB via running the New-OfflineAddressBook command in EMS:

New-OfflineAddressBook -Name <NewOABName> -AddressLists <AddressLists in this OAB>  

How can I replace new OAB?
To replace the old or default OAB with the new created one, you can use this command.

Set-OfflineAddressBook -Identity <NewOABName> -IsDefault $true  

Or you can also add the "-IsDefault $true" parameter when creating the new OAB:

New-OfflineAddressBook -Name <NewOABName> -AddressLists <AddressLists in this OAB> -isDefault $true
