When I try yo add a IP to 'Connection filter policy (Default)' I get a Client error.

"The operation couldn't be performed bacause 'Default' matches multiple entries."

What can be wrong??

    Hi @T Millred ,

    Are you trying to edit the default connection filter policy following the instructions in this document?
    Please connect to Exchange Online Powershell and run the command below to check if there are duplicate objects listed: 

    Get-HostedConnectionFilterPolicy | ft name, identity

    Besides, it's suggested to try adding the IP using Exchange Online PowerShell or standalone EOP PowerShell instead and see if the error persists. Assuming you need to add an IP 192.168.2.10 to the allow list, you can run the command below: 

    Set-HostedConnectionFilterPolicy -Identity Default -IPAllowList @{Add="192.168.2.10"}
