My helpdesk is a member of the Exchange Recipients Management group in AD and previously had access to manage Send-As in Exchange 2007. After being migrated to Exchange 2013, they no longer see the SendAs + symbol but can manage Send of Behalf of and Full Mailbox access.

Anyone run into this. I see from this article, that Recipient Management should give them the rights.

Hi,

From your description, I would like to clarify the following thing:

Send as permission is an AD permission, so they need the role Active Directory Permissions. You can run the New-ManagementRoleAssignment -Name ADPermissions Recipient Mgmt -Role Active Directory Permissions -SecurityGroup Recipient Management cmdlet to add it and check the result.

Hope this can be helpful to you.

Best regards,
