    Hi,
    Which version of Exchange are you using? Are you expericing a migration?
    What action is taken when you received the error? Any other similar errors that you did not post?

    You can try removing the spaces of the object name like step 5 in this blog: https://www.petenetlive.com/KB/Article/0000516
    Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

    Or you will need to re-create the corrupted OAB via powershell, then recreate the GAL and run commands to update:

    Get-GlobalAddressList | Update-GlobalAddressList  
    Get-AddressList | Update-AddressList
