Could Not Establish Trust Relationship for the SSL/TLS Secure Channel with Authority. (4312964)

When using a native move request to migrate to Exchange 2013 the following process takes place.

A native move needs to be executed to migrate mailboxes from EX2010 to EX2013. MAgE executes a native move as follows: Execute PowerShell: New-MoveRequest -Identity ea9666a5-5f9b-4c05-bb7c-8b0b8e6b2412 -TargetDatabase cdd1a700-043b-4adf-94a2-511d5ee63cca -RemoteGlobalCatalog server.domain.com -RemoteCredential [TEICH\svctwbqmm] -TargetDeliveryDomain server1.domain.com -BatchName QMMEX(2BB01037-E212-4872-8363-D15DB47FF6A3), TargetDB(cdd1a700-043b-4adf-94a2-511d5ee63cca) -BadItemLimit 0 -SuspendWhenReadyToComplete -Remote -RemoteHostName server3.child.domain.com

Upon executing the Native Move, the following PowerShell error appears: Error System.Management.Automation.RemoteException: The call to 'https://server3.child.domain.com/EWS/mrsproxy.svc' failed. Error details: Could not establish trust relationship for the SSL/TLS secure channel with authority 'server.child.domain.com'. --> The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. --> The remote certificate is invalid according to the validation procedure.. A certificate error is suspected, because it may be missing on the CAS array in the target (EX2013).
