   I have an open question regarding changes to the mail flow connector for Exchange Online:http://community.office365.com/en-us/f/156/p/343149/929997.aspx#929997

************************************************************************************************

Hello all,

    I'm working on a Hybrid 2010 configuration.  When modify the connectors in Exchange Online EAC, I noticed that the connectors changes, and opportunistic TLS is gone.  What happened?  Can someone please provide some information regarding the TLS changes?  Did opportunistic TLS get removed? 

I was following these articles:

Configure mail flow using connectors in Office 365

https://technet.microsoft.com/en-us/library/ms.exch.eac.connectorselection(v=exchg.150).aspx

Set up connectors to route mail between Office 365 and your own email servers

https://technet.microsoft.com/en-us/library/dn751020(v=exchg.150).aspx

Any information on theses changes will be appreciated.

Hi Kloud,

I didnt find any official documentation about that. The connectors page in Exchange admin center has just been updated, so we may not have relevant documentation at this point. If I find any, Ill let you know.

Meanwhile, I suggest you submit your feedback to let our relevant team know that you need an official documentation about the Opportunistic TLS of new connectors.

Thanks for your understanding.

Best Regards,
Allen

Do you know the answer to this question?  Or, are you planning to post something on these changes?

Thanks           

Hi,

Whats your scenario for creating a connector?

I noticed that you are using Exchange 2010-based hybrid deployment. Generally, when configuring a hybrid configuration using the Hybrid Configuration wizard, one of the things it creates is a new receive connector named Inbound from Office 365 on each hybrid transport server.

This connector is set to only accept incoming SMTP sessions from a specific set of IP ranges, which are associated with the FOPE service used in Office 365. Please check your receive connector and send connector for Hybrid environment in EAC and share the configuration information here for further analysis.

Additionally, here is a reference about Hybrid 2010 Configuration for mail flow:
