Exchange 2016 - F5 APM Mapi Issue

Hello Everyone,

 

I am in the process of deploying F5 APM in front of Exchange 2016 for users entering the environment from the internet. I have been following the Exchange 2016 deployment guide found here:

 

https://f5.com/solutions/deployment-guides/microsoft-exchange-server-2016-big-ip-v11-v12-ltm-apm-afm

 

I am not using the iApp as our configuration is more complex than the iApp handles without modification so I have opted to configure things manually. I have gotten to a point where everything is working with the exception of mapi over http. I am running version 13.1 of APM so mapi over http should be supported without issues. Whenever I launch outlook, I asked to enter credentials. After I enter credentials, it just asks again so I know I am having an authentication failure, but I am not quite sure what the cause is.

 

Within my exchange profile, I have outlook anywhere front end auth set to basic and the sso configuration is blank. This is the same configuration setting that the iApp generates if I use that. This APM forwards traffic to an LTM that sits within our network. One the exchange side outlook anywhere is set to use basic authentication.

 

Anyone have any ideas on what I could be missing?
