Exchange 2019:- Reset RBAC to default

I have a strange problem in my lab where my main account is part of the org admin group however I cannot run half the commands, I thought I would reset everything with the commands below but have not seen any change. Still cannot do much.

However in my Exchange 2016 lab, it worked just fine.

Firstly launch the Exchange Management Shell (EMS) and run the command:

• Add-PSSnapin Microsoft*

Then run the command:

• Install-CannedRbacRoles

• Install-CannedRbacRoleAssignments

After this, you can either reboot or close and open the Exchange Management Shell (EMS) to check.

Hope it helps.
