mailflow for office 365 question

Hello,
I have a question regarding inbound and outbound mail flow for Office 365. We are currently using MSLogic for inbound and outbound emails and we want both inbound and outbound maiflow to continue to go through MSLogic
After we run a Hybrid wizard I know the send connector is created to send directly to Office 365. Is it possible to set the outbound emails for even cloud users who send outside, to go on on-premises first and then through MSLogic and then outside. We are concerned that some of the messages will be NDR because MSLogic IPs and servers where white listed by our customers and for this reason we want to continue for the mailflow to go this way. Will there be any issues if this would change?

Please give your advice. Thank you very much.

It is possible, part of the idea behind hybrid is to have a centralized transport. You can review the different options you have for example here:

Do you mean MXLogic?  They have documentation to do this:  http://rdsrc.us/hZt6bSD

I don't know why you would want to use it though -- Forefront, which is included with Office 365 is pretty darn good at filtering.

When you go through the Hybrid Configuration wizard to set up a hybrid environment, one of the options you have is to have all email flow through a single environment. The wizard lets you choose which one to use and all the necessary settings are automatically configured when you select the option to use on-prem mail servers for all transport.
