Custom roles of office 365

Question

Good afternoon.

I wanted to know if it is possible to customize an office 365 role that only allows you to manage members of a shared mailbox?

If not, what is the best solution to manage the above situation?

Thanks

Answer 1

If managing members of a shared mailbox is the only action you need, you can create a custom role using the Exchange RBAC model, and even scope it to specific shared mailbox(es) only. A more generic answer is that there is only limited support for custom roles across Microsoft 365, with only certain object types/operations currently supported. Luckily, the Exchange RBAC model is very robust and can address most requirements with regards to mailboxes.

Answer 2

Assign admin roles to users using Roles

In the admin center, go to Role assignments. Choose the Azure AD or Intune tabs to view the admin roles available for your organization.
Select the admin role that you want to assign the user to.
Select Assigned admins > Add.
Type the user's display name or username, and then select the user from the list of suggestions.
Add multiple users until you're done.
Select Save, and then the user will be added to the list of assigned admins.
