We have purchased one Pay-As-You-Go subscription that was not visible in azure old portal (management portal) but its visible in new portal!
I have given the contributer role
Please let me know how I can add in old management portal
Thank, Nihal
In order to access old management portal, you need to be added as a co-administrator there. A Contributor role is specific to Azure's Role-based access control (RBAC) and only new portal is aware of them. Old portal doesn't know anything about RBAC and only users added as administrators (administrators, co-administrator, service administrator etc.) can access old portal.
Please ask your account administrator to add you as a co-administrator. Please see this link for more details: https://azure.microsoft.com/en-in/documentation/articles/billing-add-change-azure-subscription-administrator/.
