Hello Everyone,
Our Customer organization consists of mixed Exchange 2013/2007 Environment and they are in the process of moving rest of mailboxes to the new environment.
Unfortunately after moving some linked mailboxes to the Exchange 2013 Env. they discovered that those migrated users cannot connect by their smartphones.
ExRca for the each linked mailbox generate following Error (bellow OPTIONS section)
The underlying connection was closed: An unexpected error occurred on a receive.
System.Net.WebException at System.Net.HttpWebRequest.GetResponse() at Microsoft.Exchange.Tools.ExRca.Extensions.RcaHttpRequest.GetResponse()
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

The connections for the Ex2007 users are established through the another (separated) reverse proxy and sync for the regural and linked mailboxes works well.
They published ActiveSync for the Exchange 2013 users by preparing the new DNS name and the new public IP address (for the separation of the Exchange 2007 mailboxes connection).
So all connections for the regular Exchange 2013 mailboxes going well , unfortunately except Exchange 2013 linked mailboxes (regardless of witch linked mailbox smtp domain we choose)
ActiveSync Web Directory settings for each exchange 2013 server are as follows:
Server : SERVERNAME
ExtendedProtectionTokenChecking : None
ExtendedProtectionFlags : {}
ExtendedProtectionSPNList : {}
ExternalUrl : https://mail.domain.com/Microsoft-Server-ActiveSync
ExternalAuthenticationMethods : {}
RemoteDocumentsInternalDomainSuffixList : {}
InternalUrl : https://mail.domain.com/Microsoft-Server-ActiveSync
InternalAuthenticationMethods : {}
MobileClientCertificateAuthorityURL :
BasicAuthEnabled : True
WindowsAuthEnabled : True
ClientCertAuth : Ignore
InternalAuthenticationMethods : {}
ExternalAuthenticationMethods : {}
WebSiteSSLEnabled : True
Certificate is signed by the Inside organization PKI and contains the new DNS name (in SAN section)
Thanks in advance for any help.
Regards,
HM
