We're in a coexistence state while migrating from Exchange 2010 to Exchange 2016. Our Access Management team are in the Recipient Management Role. When they select the option to "Connect a Mailbox" from the EAC, the pop-up window is blank.
They do have the ability to reconnect mailboxes in the 2010 environment.
If I open the window as Org admin, I have the options to see disconnected mailboxes.
Is there a new role they need to be added to in the 2016 environment?
