Sharepoint policy 1.4 setting RequireAcceptingAccountMatchInvitedAccount seems to be deprecated or ignored

[tkol2022]

🐛 Summary

The Sharepoint admin setting for policy 1.4 "Guests must sign in using the same account to which sharing invitations are sent", backend field RequireAcceptingAccountMatchInvitedAccount looks like it is being deprecated or simply ignored. We can no longer locate this setting in any of the test tenant Sharepoint admin centers and when we execute the code below, it does nothing and the value of the variable always comes back false. We are not the only ones experiencing this problem.

It is not clear yet but we might need to turn off or remove this from Scuba, because it doesn't make sense to have a policy that A) doesn't exist in the admin center and B) the user cannot configure via Powershell either.

Set-PnPTenant -RequireAcceptingAccountMatchInvitedAccount $true
(Get-PnPTenant).RequireAcceptingAccountMatchInvitedAccount # this always returns $false

This is the respective setting described in the baseline.
