You can't use TenantAllowBlockList when connected to Security and Compliance

Andres Bohren

Hi All,

Recently i was stumbling across a weird behaviour regarding Exchange Online Protection (EOP) with TenantAllowBlockListItems.

Connect-ExchangeOnline
Get-TenantAllowBlockListItems -ListType Url -Block
Get-TenantAllowBlockListItems -ListType Url -ListSubType AdvancedDelivery

Represented with the following Command

Get-TenantAllowBlockListItems -ListType Url -Block

Advanced Delivery - Represented with the following Command

Get-TenantAllowBlockListItems -ListType Url -ListSubType AdvancedDelivery

Then i connected to Security and Compliance

Connect-IPPSSession
Get-TenantAllowBlockListItems -ListType Url

Error: Das Format des in den Parameter objectId eingegebenen Werts ist ungültig. Prüfen Sie den Wert, und versuchen Sie es erneut.

Parameter name: objectId

   List.GetTenantAllowBlockListItems

    + PSComputerName        : che01b.ps.compliance.protection.outlook.com


Get-TenantAllowBlockListItems -ListType Url -ListSubType AdvancedDelivery
