How to disable autoforwarding option in office 365?

Question

Im struggling to disable autoforwarding option of emails in office 365. I wish to remove highlighted autoforwarding option entirely.

So i followed, https://blogs.technet.microsoft.com/exovoice/2017/12/07/disable-automatic-forwarding-in-office-365-and-exchange-server-to-prevent-information-leakage/

I logged into office 365 tenant in powershell and executed below commands

New-ManagementRole MyBaseOptions-DisableForwarding -Parent MyBaseOptions

Set-ManagementRoleEntry MyBaseOptions-DisableForwarding\Set-Mailbox -RemoveParameter -Parameters DeliverToMailboxAndForward,ForwardingAddress,ForwardingSmtpAddress

Then created a new RoleAssignmentPolicy called "DisabledForwardingRoleAssignmentPolicy"

New-RoleAssignmentPolicy -Name DisabledForwardingRoleAssignmentPolicy -Roles MyBaseOptions-DisableForwarding,MyContactInformation,MyRetentionPolicies,MyMailSubscriptions,MyTextMessaging,MyVoiceMail,MyDistributionGroupMembership,MyDistributionGroups, MyProfileInformation

and did what was said in the referenced link. tick only "MyBaseOptions-DisableForwarding"

and assigned to a user

Waited few hours and see whether the autoforwarding option is vanished for that user.
Its not just the same. it is there as usual. What I am missing ? cant figure out. please help me to solve this.

PS: Note:

Apparently i tried with creating a new fresh user and applied my role assignment policy "DisabledForwardingRoleAssignmentPolicy"` and it worked for the fresh profile. it will remove autoforwarding for new account.

But already created old accounts this did not work., any possibility to force/refresh the policy to old profiles ? Cant understand why it is not applying to old emails.

Thanks in advance for any clue

Answer 1

Finally I found out that tt is not something to do with old profiles vs new profiles. If a user is a globaladmin in office 365 his/her profile will not be applied above policy. May be its by design. not sure though. already project in techcommunity.microsoft.com ,
