Mail flow permissions

The permissions required to perform tasks related to mail flow vary depending on the procedure being performed or the cmdlet you want to run. For more information about transport features, see Mail flow and the transport pipeline.

This topic lists the permissions required to manage the mail flow features in Exchange Server 2016 and Exchange Server 2019. For information about how Office 365 permissions relate to Exchange permissions, see Permissions in Office 365.

To find out what permissions you need to perform the procedure or run the cmdlet, do the following:

  1. In the table below, find the feature that is most related to the procedure you want to perform or the cmdlet you want to run.

  2. Next, look at the permissions required for the feature. You must be assigned one of those role groups, an equivalent custom role group, or an equivalent management role. You can also click a role group to see its management roles. If a feature lists more than one role group, you need to be assigned to only one of the role groups to use the feature. For more information about role groups and management roles, see Understanding Role Based Access Control.

  3. Now, run the Get-ManagementRoleAssignment cmdlet to look at the role groups or management roles assigned to you to see if you have the permissions that are necessary to manage the feature.

    Note

    You must be assigned the Role Management management role to run the Get-ManagementRoleAssignment cmdlet. If you don't have permissions to run the Get-ManagementRoleAssignment cmdlet, ask your Exchange administrator to retrieve the role groups or management roles assigned to you.

If you want to delegate the ability to manage a feature to another user, see Delegate role assignments.

Note

Some features that you want to manage might exist on Edge Transport servers. To manage features on Edge Transport servers, you need to become a member of the Local Administrators group on the Edge Transport server you want to manage. Edge Transport servers don't use Role Based Access Control (RBAC). Features that can be managed on Edge Transport servers have Edge Transport Local Administrator in the "Permissions required" column in the table below.

Note

Some features may require that you have local administrator permissions on the server you want to manage. To manage these features, you must be a member of the Local Administrators group on that server.

Mail flow permissions

You can use the features in the following tables to configure mail flow settings in the Front End Transport, Mailbox Transport, and Transport services on Mailbox servers, and on Edge Transport servers. The permissions that are required to configure each feature are listed.

Users who are assigned the View Only Management role group can view the configuration of the features shown in the following table. For more information, see View Only Organization Management.
