hello
we have exchange 2010 SP3 Rollup 2 with Symantec Messaging Gateway version 9.5.3 as our SMTP gateway.
our exchange environment is:
6 Mailbox servers
6 CAS servers
4 HUB servers
and 4 Symantec Messaging gateway
we have SSO and ADFS in configured also.
the issue is with the send/receive connectors between the exchange and Office 365, how it should be configured, keeping in mind our HUB servers doesnt have internet in them everything is going through the Symantec Messaging serve.
thanks
